Release notes

The release notes provide information about deprecations and breaking changes in Grafana Agent static mode.

For a complete list of changes to Grafana Agent, with links to pull requests and related issues when available, refer to the Changelog.

Note: These release notes are specific to Grafana Agent static mode. Other release notes for the different Grafana Agent variants are contained on separate pages:

v0.35

Breaking change: Jaeger remote sampling no longer configurable using the Jaeger receiver

Jaeger remote sampling used to be configured using the Jaeger receiver configuration. This receiver was updated to a new version, where support for remote sampling in the receiver was removed.

Jaeger remote sampling is available as a separate configuration field starting in v0.35.3.

Old configuration example:

yaml 
receivers:
  jaeger:
    protocols:
      grpc:
    remote_sampling:
      strategy_file: /etc/agent/strategies.json
      strategy_file_reload_interval: 1s

New configuration example:

yaml 
jaeger_remote_sampling:
  - source:
      file: /etc/agent/strategies.json
      reload_interval: 1s

Breaking change: auth and version attributes from walk_params block of SNMP integration have been removed

The SNMP integrations (both v1 and v2) wrap a new version of SNMP exporter which introduces a new configuration file format. This new format separates the walk and metric mappings from the connection and authentication settings. This allows for easier configuration of different auth params without having to duplicate the full walk and metric mapping.

Old configuration example:

yaml 
    snmp_targets:
      - name: network_switch_1
        address: 192.168.1.2
        module: if_mib
        walk_params: public
        auth: public
    walk_params:
      public:
        retries: 2
        version: 2
        auth:
          community: public

New configuration example:

yaml 
    snmp_targets:
      - name: network_switch_1
        address: 192.168.1.2
        module: if_mib
        walk_params: public
        auth: public
    walk_params:
      public:
        retries: 2

See Module and Auth Split Migration for more details.

Removal of Dynamic Configuration

The experimental feature Dynamic Configuration has been removed. The use case of dynamic configuration will be replaced with Modules in Grafana Agent Flow.

Breaking change: Removed and renamed tracing metrics

In the traces subsystem for Static mode some metrics are removed and others are renamed. The reason for the removal is a bug which caused the metrics to be incorrect if more than one instance of a traces configuration is specified.

Removed metrics:

  • “blackbox_exporter_config_last_reload_success_timestamp_seconds” (gauge)
  • “blackbox_exporter_config_last_reload_successful” (gauge)
  • “blackbox_module_unknown_total” (counter)
  • “traces_processor_tail_sampling_count_traces_sampled” (counter)
  • “traces_processor_tail_sampling_new_trace_id_received” (counter)
  • “traces_processor_tail_sampling_sampling_decision_latency” (histogram)
  • “traces_processor_tail_sampling_sampling_decision_timer_latency” (histogram)
  • “traces_processor_tail_sampling_sampling_policy_evaluation_error” (counter)
  • “traces_processor_tail_sampling_sampling_trace_dropped_too_early” (counter)
  • “traces_processor_tail_sampling_sampling_traces_on_memory” (gauge)
  • “traces_receiver_accepted_spans” (counter)
  • “traces_receiver_refused_spans” (counter)
  • “traces_exporter_enqueue_failed_log_records” (counter)
  • “traces_exporter_enqueue_failed_metric_points” (counter)
  • “traces_exporter_enqueue_failed_spans” (counter)
  • “traces_exporter_queue_capacity” (gauge)
  • “traces_exporter_queue_size” (gauge)

Renamed metrics:

  • “traces_receiver_refused_spans” is renamed to “traces_receiver_refused_spans_total”
  • “traces_receiver_accepted_spans” is renamed to “traces_receiver_refused_spans_total”
  • “traces_exporter_sent_metric_points” is renamed to “traces_exporter_sent_metric_points_total”

v0.33

We’ve removed the deprecated symbolic links to /bin/agent* in Docker containers, as planned in v0.31. In case you’re setting a custom entrypoint, use the new binaries that are prefixed with /bin/grafana*.

Deprecation of Dynamic Configuration

Dynamic Configuration will be removed in v0.34. The use case of dynamic configuration will be replaced with Modules in Grafana Agent Flow.

v0.32

Breaking change: node_exporter configuration options changed

With the update of the node_exporter integration to use v1.5.0, configuration options for the diskstats collector have changed names:

  • diskstats_ignored_devices is now diskstats_device_exclude in the static mode configuration.
  • ignored_devices is now device_exclude in the Flow component configuration.

v0.31.1

Breaking change: all Windows executables are now zipped

All release Windows .exe files are now zipped. Prior to v0.31, only grafana-agent-installer.exe was unzipped.

This fixes an issue from v0.31.0 where all .exe files were accidentally left unzipped.

v0.31

Breaking change: binary names are now prefixed with grafana-

As first announced in v0.29, release binary names are now prefixed with grafana-:

  • agent is now grafana-agent.
  • agentctl is now grafana-agentctl.

For the grafana/agent Docker container, the entrypoint is now /bin/grafana-agent. A symbolic link from /bin/agent to the new binary has been added.

For the grafana/agentctl Docker container, the entrypoint is now /bin/grafana-agentctl. A symbolic link from /bin/agentctl to the new binary has been added.

These symbolic links will be removed in v0.33. Custom entrypoints must be updated prior to v0.33 to use the new binaries before the symbolic links get removed.

v0.30

Breaking change: ebpf_exporter integration removed

The ebpf_exporter version bundled in the Agent used bcc to compile eBPF programs at runtime. This made it hard to run successfully, as the dynamic linking approach required a compiler, the correct kernel headers, as well as an exact match of the libbpf toolchain on the host system. For these reasons, we’ve decided to remove the ebpf_exporter integration.

Running the ebpf_exporter integration is now deprecated and will result in configuration errors. To continue using the same configuration file, remove the ebpf block.

v0.29

Breaking change: JSON-encoded traces from OTLP versions below 0.16.0 are no longer supported

Grafana Agent’s OpenTelemetry Collector dependency has been updated from v0.55.0 to v0.61.0. OpenTelemetry Collector v0.58.0 no longer translates from InstrumentationLibrary to Scope.

This means that JSON-encoded traces that still use InstrumentationLibrary will be dropped. To work around this issue, either send traces using protobuf or update your OTLP protocol version to v0.16.0 or newer.

Deprecation: binary names will be prefixed with grafana- in v0.31.0

The binary names agent and agentctl have been deprecated and will be renamed to grafana-agent and grafana-agentctl respectively in the v0.31.0 release.

As part of this change, the Docker containers for the v0.31.0 release will include symbolic links from the old binary names to the new binary names.

There is no action to take at this time.

v0.26

Breaking change: Deprecated YAML fields in server block removed

The YAML fields which were first deprecated in the v0.24.0 release have now been removed, replaced by equivalent command line flags. Please refer to the original deprecation notice for instructions for how to migrate to the command line flags.

Breaking change: Reconcile sampling policies between Agent and OTel

Configuring sampling policies in the tail_sampling block of the traces block has been changed to be equal with the upstream configuration of the OTel processor. It now requires that the policy type is specified.

Old configuration:

yaml 
traces:
  configs:
    - name: default
    ...
    tail_sampling:
      policies:
      - latency:
          threshold_ms: 100

New configuration:

yaml 
traces:
  configs:
    - name: default
    ...
    tail_sampling:
      policies:
      - type: latency
        latency:
          threshold_ms: 100

v0.24

Breaking change: Integrations renamed when integrations-next feature flag is used

This change only applies to users utilizing the integrations-next feature flag. Nothing is changed for configuring integrations when the feature flag is not used.

Most integrations-next integrations have been renamed to describe what telemetry data they generate instead of the projects they are powered by.

  • consul_exporter is now consul
  • dnsmasq_exporter is now dnsmasq
  • elasticsearch_exporter is now elasticsearch
  • github_exporter is now github
  • kafka_exporter is now kafka
  • memcached_exporter is now memcached
  • mongodb_exporter is now mongodb
  • mysqld_exporter is now mysql
    • Note that it is mysql and not mysqld
  • postgres_exporter is now postgres
  • process_exporter is now process
  • redis_exporter is now redis
  • statsd_exporter is now statsd
  • windows_exporter is now windows

Keys in the integrations config block have changed to match the above:

  • integrations.consul_exporter_configs is now integrations.consul_configs
  • integrations.dnsmasq_exporter_configs is now integrations.dnsmasq_configs
  • integrations.elasticsearch_exporter_configs is now integrations.elasticsearch_configs
  • integrations.github_exporter_configs is now integrations.github_configs
  • integrations.kafka_exporter_configs is now integrations.kafka_configs
  • integrations.memcached_exporter_configs is now integrations.memcached_configs
  • integrations.mongodb_exporter_configs is now integrations.mongodb_configs
  • integrations.mysqld_exporter_configs is now integrations.mysql_configs
  • integrations.postgres_exporter_configs is now integrations.postgres_configs
  • integrations.process_exporter is now integrations.process
  • integrations.redis_exporter_configs is now integrations.redis_configs
  • integrations.statsd_exporter is now integrations.statsd
  • integrations.windows_exporter is now integrations.windows

Integrations not listed here have not changed; node_exporter still has the same name.

This change propagates to the label values generated by these integrations. For example, job="integrations/redis_exporter will now be job="redis".

Change: Separating YAML and command line flags

As of this release, we are starting to separate what can be configured within the YAML file, and what can be configured by command line flag. Previously, there was a lot of overlap: many things could be set by both command line flag and configuration file, with command line flags taking precedence.

The configuration file will be used for settings that can be updated at runtime using the /-/reload endpoint or sending SIGHUP. Meanwhile, command line flags will be used for settings that must remain consistent throughout the process lifetime, such as the HTTP listen port.

This conceptual change will require some number of breaking changes. This release focuses on the server block of the YAML, which has historically caused the most issues with the /-/reload endpoint working correctly.

There may be more breaking changes in the future as we identify more settings that must be static and moved to flags. These changes will either be moving a YAML field to a flag or moving a flag to a YAML field. After we are done with this migration, there will be no overlap between flags and the YAML file.

Deprecation on YAML fields in server block that have flags

The server block is the most impacted by the separation of flags/fields. Instead of making a breaking change immediately, we are deprecating these fields.

NOTE: These deprecated fields will be removed in the v0.26.0 release. We will communicate when other deprecated features will be removed when a timeline is established.

The following fields are now deprecated in favor of command line flags:

  • server.register_instrumentation
  • server.graceful_shutdown_timeout
  • server.log_source_ips_enabled
  • server.log_source_ips_header
  • server.log_source_ips_regex
  • server.http_listen_network
  • server.http_listen_address
  • server.http_listen_port
  • server.http_listen_conn_limit
  • server.http_server_read_timeout
  • server.http_server_write_timout
  • server.http_server_idle_timeout
  • server.grpc_listen_network
  • server.grpc_listen_address
  • server.grpc_listen_port
  • server.grpc_listen_conn_limit
  • server.grpc_server_max_recv_msg_size
  • server.grpc_server_max_send_msg_size
  • server.grpc_server_max_concurrent_streams
  • server.grpc_server_max_connection_idle
  • server.grpc_server_max_connection_age
  • server.grpc_server_max_connection_age_grace
  • server.grpc_server_keepalive_time
  • server.grpc_server_keepalive_timeout
  • server.grpc_server_min_time_between_pings
  • server.grpc_server_ping_without_stream_allowed

This is most of the fields; the remaining non-deprecated fields are server.log_level, server.log_format, server.http_tls_config, and server.grpc_tls_config, which support dynamic updating.

Breaking change: Removing support for dynamically updating deprecated server fields

/-/reload will now fail if any of the deprecated server block fields have changed. It is still valid to change a non-deprecated field (i.e., changing the log level).

Breaking change: Server-specific command line flags have changed

The following flags are new:

  • -server.http.enable-tls
  • -server.grpc.enable-tls
  • -server.http.address
  • -server.grpc.address

The following flags have been removed:

  • -log.level (replacement: use YAML field server.log_level)
  • -log.format (replacement: use YAML field server.log_format)
  • -server.http-tls-cert-path (replacement: use YAML field server.http_tls_config)
  • -server.http-tls-key-path (replacement: use YAML field server.http_tls_config)
  • -server.http-tls-client-auth (replacement: use YAML field server.http_tls_config)
  • -server.http-tls-ca-path (replacement: use YAML field server.http_tls_config)
  • -server.grpc-tls-cert-path (replacement: use YAML field server.grpc_tls_config)
  • -server.grpc-tls-key-path (replacement: use YAML field server.grpc_tls_config)
  • -server.grpc-tls-client-auth (replacement: use YAML field server.grpc_tls_config)
  • -server.grpc-tls-ca-path (replacement: use YAML field server.grpc_tls_config)
  • -server.http-listen-address (replacement: use the new -server.http.address flag, which combines host and port)
  • -server.http-listen-port (replacement: use the new -server.http.address flag, which combines host and port)
  • -server.grpc-listen-address (replacement: use the new -server.grpc.address flag, which combines host and port)
  • -server.grpc-listen-port (replacement: use the new -server.grpc.address flag, which combines host and port)
  • -server.path-prefix (no replacement; this flag was unsupported and caused undefined behavior when set)

The following flags have been renamed:

  • -server.log-source-ips-enabled has been renamed to -server.log.source-ips.enabled
  • -server.log-source-ips-header has been renamed to -server.log.source-ips.header
  • -server.log-source-ips-regex has been renamed to -server.log.source-ips.regex
  • -server.http-listen-network has been renamed to -server.http.network
  • -server.http-conn-limit has been renamed to -server.http.conn-limit
  • -server.http-read-timeout has been renamed to -server.http.read-timeout
  • -server.http-write-timeout has been renamed to -server.http.write-timeout
  • -server.http-idle-timeout has been renamed to -server.http.idle-timeout
  • -server.grpc-listen-network has been renamed to -server.grpc.network
  • -server.grpc-conn-limit has been renamed to -server.grpc.conn-limit
  • -server.grpc-max-recv-msg-size-bytes has been renamed to -server.grpc.max-recv-msg-size-bytes
  • -server.grpc-max-send-msg-size-bytes has been renamed to -server.grpc.max-send-msg-size-bytes
  • -server.grpc-max-concurrent-streams has been renamed to -server.grpc.max-concurrent-streams

Breaking change: New TLS flags required for enabling TLS

The two new flags, -server.http.enable-tls and -server.grpc.enable-tls now must be provided for TLS support to be enabled.

This is a change over the previous behavior where TLS was automatically enabled when a certificate pair was provided.

Breaking change: Default HTTP/gRPC address changes

The HTTP and gRPC listen addresses now default to 127.0.0.1:12345 and 127.0.0.1:12346 respectively.

If running inside of a container, you must change these to 0.0.0.0 to externally communicate with the agent’s HTTP server.

The listen addresses may be changed via -server.http.address and -server.grpc.address respectively.

Breaking change: Removal of -reload-addr and -reload-port flags

The -reload-addr and -reload-port flags have been removed. They were initially added to workaround an issue where reloading a changed server block would cause the primary HTTP server to restart. As the HTTP server settings are now static, this can no longer happen, and as such the flags have been removed.

Change: In-memory autoscrape for integrations-next

This change is only relevant to those using the integrations-next feature flag.

In-memory connections will now be used for autoscraping-enabled integrations. This is a change over the previous behavior where autoscraping integrations would connect to themselves over the network. As a result of this change, the integrations.client_config field is no longer necessary and has been removed.

v0.22

node_exporter integration deprecated field names

The following field names for the node_exporter integration are now deprecated:

  • netdev_device_whitelist is deprecated in favor of netdev_device_include.
  • netdev_device_blacklist is deprecated in favor of netdev_device_exclude.
  • systemd_unit_whitelist is deprecated in favor of systemd_unit_include.
  • systemd_unit_blacklist is deprecated in favor of systemd_unit_exclude.
  • filesystem_ignored_mount_points is deprecated in favor of filesystem_mount_points_exclude.
  • filesystem_ignored_fs_types is deprecated in favor of filesystem_fs_types_exclude.

This change aligns with the equivalent flag names also being deprecated in the upstream node_exporter.

Support for the old field names will be removed in a future version. A warning will be logged if using the old field names when the integration is enabled.

v0.21.2, v0.20.1

Disabling of config retrieval endpoints

These two patch releases, as part of a fix for CVE-2021-41090, disable the /-/config and /agent/api/v1/configs/{name} endpoints by default. Pass the --config.enable-read-api flag at the command line to re-enable them.

v0.21

Integrations: Change in how instance labels are handled (Breaking change)

Integrations will now use a SUO-specific instance label value. Integrations that apply to a whole machine or agent will continue to use <agent machine hostname>:<agent listen port>, but integrations that connect to an external system will now infer an appropriate value based on the config for that specific integration. Please refer to the documentation for each integration for which defaults are used.

Note: In some cases, a default value for instance cannot be inferred. This is the case for mongodb_exporter and postgres_exporter if more than one SUO is being connected to. In these cases, the instance value can be manually set by configuring the instance field on the integration. This can also be useful if two agents infer the same value for instance for the same integration.

As part of this change, the agent_hostname label is permanently affixed to self-scraped integrations and cannot be disabled. This disambiguates multiple agents using the same instance label for an integration, and allows users to identify which agents need to be updated with an override for instance.

Both use_hostname_label and replace_instance_label are now both deprecated and ignored from the YAML file, permanently treated as true. A future release will remove these fields, causing YAML errors on load instead of being silently ignored.

v0.20

Traces: Changes to receiver’s TLS config (Breaking change).

Upgrading to OpenTelemetry v0.36.0 contains a change in the receivers TLS config. TLS params have been changed from being squashed to being in its own block. This affect the jaeger receiver’s remote_sampling config.

Example old config:

yaml 
receivers:
  jaeger:
    protocols:
      grpc: null,
    remote_sampling:
      strategy_file: <file_path>
      insecure: true

Example new config:

yaml 
receivers:
  jaeger:
    protocols:
      grpc: null,
    remote_sampling:
      strategy_file: <file_path>
      tls:
        insecure: true

Traces: push_config is no longer supported (Breaking change)

push_config was deprecated in favor of remote_write in v0.14.0, while maintaining backwards compatibility. Refer to the deprecation announcement for how to upgrade.

Traces: legacy OTLP gRPC port no longer default port

OTLP gRPC receivers listen at port 4317 by default, instead of at port 55680. This goes in line with OTLP legacy port deprecation.

To upgrade, point the client instrumentation push endpoint to :4317 if using the default OTLP gRPC endpoint.

v0.19

Traces: Deprecation of “tempo” in config and metrics. (Deprecation)

The term tempo in the config has been deprecated of favor of traces. This change is to make intent clearer.

Example old config:

yaml 
tempo:
  configs:
    - name: default
      receivers:
        jaeger:
          protocols:
            thrift_http:

Example of new config:

yaml 
traces:
  configs:
    - name: default
      receivers:
        jaeger:
          protocols:
            thrift_http:

Any tempo metrics have been renamed from tempo_* to traces_*.

Tempo: split grouping by trace from tail sampling config (Breaking change)

Load balancing traces between agent instances has been moved from an embedded functionality in tail sampling to its own configuration block. This is done due to more processor benefiting from receiving consistently receiving all spans for a trace in the same agent to be processed, such as service graphs.

As a consequence, tail_sampling.load_balancing has been deprecated in favor of a load_balancing block. Also, port has been renamed to receiver_port and moved to the new load_balancing block.

Example old config:

yaml 
tail_sampling:
  policies:
    - always_sample:
  port: 4318
  load_balancing:
    exporter:
      insecure: true
    resolver:
      dns:
        hostname: agent
        port: 4318

Example new config:

yaml 
tail_sampling:
  policies:
    - always_sample:
load_balancing:
  exporter:
    insecure: true
  resolver:
    dns:
      hostname: agent
      port: 4318
  receiver_port: 4318

Metrics: Deprecation of “prometheus” in config. (Deprecation)

The term prometheus in the config has been deprecated of favor of metrics. This change is to make it clearer when referring to Prometheus or another Prometheus-like database, and configuration of Grafana Agent to send metrics to one of those systems.

Old configs will continue to work for now, but support for the old format will eventually be removed. To migrate your config, change the prometheus key to metrics.

Example old config:

yaml 
prometheus:
  configs:
    - name: default
      host_filter: false
      scrape_configs:
        - job_name: local_scrape
          static_configs:
            - targets: ['127.0.0.1:12345']
              labels:
                cluster: 'localhost'
      remote_write:
        - url: http://localhost:9009/api/prom/push

Example new config:

yaml 
metrics:
  configs:
    - name: default
      host_filter: false
      scrape_configs:
        - job_name: local_scrape
          static_configs:
            - targets: ['127.0.0.1:12345']
              labels:
                cluster: 'localhost'
      remote_write:
        - url: http://localhost:9009/api/prom/push

Tempo: prom_instance rename (Breaking change)

As part of prometheus being renamed to metrics, the spanmetrics prom_instance field has been renamed to metrics_instance. This is a breaking change, and the old name will no longer work.

Example old config:

yaml 
tempo:
  configs:
  - name: default
    spanmetrics:
      prom_instance: default

Example new config:

yaml 
tempo:
  configs:
  - name: default
    spanmetrics:
      metrics_instance: default

Logs: Deprecation of “loki” in config. (Deprecation)

The term loki in the config has been deprecated of favor of logs. This change is to make it clearer when referring to Grafana Loki, and configuration of Grafana Agent to send logs to Grafana Loki.

Old configs will continue to work for now, but support for the old format will eventually be removed. To migrate your config, change the loki key to logs.

Example old config:

yaml 
loki:
  positions_directory: /tmp/loki-positions
  configs:
  - name: default
    clients:
      - url: http://localhost:3100/loki/api/v1/push
    scrape_configs:
    - job_name: system
      static_configs:
      - targets: ['localhost']
        labels:
          job: varlogs
          __path__: /var/log/*log

Example new config:

yaml 
logs:
  positions_directory: /tmp/loki-positions
  configs:
  - name: default
    clients:
      - url: http://localhost:3100/loki/api/v1/push
    scrape_configs:
    - job_name: system
      static_configs:
      - targets: ['localhost']
        labels:
          job: varlogs
          __path__: /var/log/*log

Tempo: Deprecation of “loki” in config. (Deprecation)

As part of the loki to logs rename, parts of the automatic_logging component in Tempo have been updated to refer to logs_instance instead.

Old configurations using loki_name, loki_tag, or backend: loki will continue to work as of this version, but support for the old config format will eventually be removed.

Example old config:

yaml 
tempo:
  configs:
  - name: default
    automatic_logging:
      backend: loki
      loki_name: default
      spans: true
      processes: true
      roots: true
    overrides:
      loki_tag: tempo

Example new config:

yaml 
tempo:
  configs:
  - name: default
    automatic_logging:
      backend: logs_instance
      logs_instance_name: default
      spans: true
      processes: true
      roots: true
    overrides:
      logs_instance_tag: tempo

v0.18

Tempo: Remote write TLS config

Tempo remote_write now supports configuring TLS settings in the trace exporter’s client. insecure_skip_verify is moved into this setting’s block.

Old configurations with insecure_skip_verify outside tls_config will continue to work as of this version, but support will eventually be removed. If both insecure_skip_verify and tls_config.insecure_skip_verify are used, then the latter take precedence.

Example old config:

tempo:
  configs:
    - name: default
      remote_write:
        - endpoint: otel-collector:55680
          insecure: true
          insecure_skip_verify: true

Example new config:

tempo:

v0.15

Tempo: automatic_logging changes

Tempo automatic logging previously assumed that the operator wanted to log to a Loki instance. With the addition of an option to log to stdout a new field is required to maintain the old behavior.

Example old config:

tempo:
  configs:
  - name: default
    automatic_logging:
      loki_name: <some loki instance>

Example new config:

tempo:
  configs:
  - name: default
    automatic_logging:
      backend: loki
      loki_name: <some loki instance>

v0.14

Scraping Service security change

v0.14.0 changes the default behavior of the scraping service config management API to reject all configuration files that read credentials from a file on disk. This prevents malicious users from crafting an instance config file that read arbitrary files on disk and send their contents to remote endpoints.

To revert to the old behavior, add dangerous_allow_reading_files: true in your scraping_service config.

Example old config:

yaml 
prometheus:
  scraping_service:
    # ...

Example new config:

yaml 
prometheus:
  scraping_service:
    dangerous_allow_reading_files: true
    # ...

SigV4 config change

v0.14.0 updates the internal Prometheus dependency to 2.26.0, which includes native support for SigV4, but uses a slightly different configuration structure than the Grafana Agent did.

To migrate, remove the enabled key from your sigv4 configs. If enabled was the only key, define sigv4 as an empty object: sigv4: {}.

Example old config:

yaml 
sigv4:
  enabled: true
  region: us-east-1

Example new config:

yaml 
sigv4:
  region: us-east-1

Tempo: push_config deprecation

push_config is now deprecated in favor of a remote_write array which allows for sending spans to multiple endpoints. push_config will be removed in a future release, and it is recommended to migrate to remote_write as soon as possible.

To migrate, move the batch options outside the push_config block. Then, add a remote_write array and move the remaining of your push_config block inside it.

Example old config:

yaml 
tempo:
  configs:
    - name: default
      receivers:
        otlp:
          protocols:
            gpc:
      push_config:
        endpoint: otel-collector:55680
        insecure: true
        batch:
          timeout: 5s
          send_batch_size: 100

Example migrated config:

yaml 
tempo:
  configs:
    - name: default
      receivers:
        otlp:
          protocols:
            gpc:
      remote_write:
        - endpoint: otel-collector:55680
          insecure: true
      batch:
        timeout: 5s
        send_batch_size: 100

v0.12

v0.12 had two breaking changes: the tempo and loki sections have been changed to require a list of tempo/loki configs rather than just one.

Tempo Config Change

The Tempo config (tempo in the config file) has been changed to store configs within a configs list. This allows for defining multiple Tempo instances for collecting traces and forwarding them to different OTLP endpoints.

To migrate, add a configs: array and move your existing config inside of it. Give the element a name: default field.

Each config must have a unique non-empty name. default is recommended for users that don’t have other configs. The name of the config will be added as a tempo_config label for metrics.

Example old config:

yaml 
tempo:
  receivers:
    jaeger:
      protocols:
        thrift_http:
  attributes:
    actions:
    - action: upsert
      key: env
      value: prod
  push_config:
    endpoint: otel-collector:55680
    insecure: true
    batch:
      timeout: 5s
      send_batch_size: 100

Example migrated config:

yaml 
tempo:
  configs:
  - name: default
    receivers:
      jaeger:
        protocols:
          thrift_http:
    attributes:
      actions:
      - action: upsert
        key: env
        value: prod
    push_config:
      endpoint: otel-collector:55680
      insecure: true
      batch:
        timeout: 5s
        send_batch_size: 100

Loki Promtail Config Change

The Loki Promtail config (loki in the config file) has been changed to store configs within a configs list. This allows for defining multiple Loki Promtail instances for collecting logs and forwarding them to different Loki servers.

To migrate, add a configs: array and move your existing config inside of it. Give the element a name: default field.

Each config must have a unique non-empty name. default is recommended for users that don’t have other configs. The name of the config will be added as a loki_config label for Loki Promtail metrics.

Example old config:

yaml 
loki:
  positions:
    filename: /tmp/positions.yaml
  clients:
    - url: http://loki:3100/loki/api/v1/push
  scrape_configs:
  - job_name: system
    static_configs:
      - targets:
        - localhost
        labels:
          job: varlogs
          __path__: /var/log/*log

Example migrated config:

yaml 
loki:
  configs:
  - name: default
    positions:
      filename: /tmp/positions.yaml
    clients:
      - url: http://loki:3100/loki/api/v1/push
    scrape_configs:
    - job_name: system
      static_configs:
        - targets:
          - localhost
          labels:
            job: varlogs
            __path__: /var/log/*log
