Documentation Grafana Alloy Reference Components otelcol otelcol.receiver.zipkin

otelcol.receiver.zipkin

otelcol.receiver.zipkin accepts Zipkin-formatted traces over the network and forwards it to other otelcol.* components.

NOTE: otelcol.receiver.zipkin is a wrapper over the upstream OpenTelemetry Collector zipkin receiver. Bug reports or feature requests will be redirected to the upstream repository, if necessary.

Multiple otelcol.receiver.zipkin components can be specified by giving them different labels.

Usage

alloy Copy

otelcol.receiver.zipkin "LABEL" {
  output {
    traces = [...]
  }
}

Arguments

otelcol.receiver.zipkin supports the following arguments:

If parse_string_tags is true, string tags and binary annotations are converted to int, bool, and float if possible. String tags and binary annotations that cannot be converted remain unchanged.

Blocks

The following blocks are supported inside the definition of otelcol.receiver.zipkin:

The > symbol indicates deeper levels of nesting. For example, grpc > tls refers to a tls block defined inside a grpc block.

tls block

The tls block configures TLS settings used for a server. If the tls block isn’t provided, TLS won’t be used for connections to the server.

The following arguments are supported:

If reload_interval is set to "0s", the certificate never reloaded.

The following pairs of arguments are mutually exclusive and can’t both be set simultaneously:

• ca_pem and ca_file
• cert_pem and cert_file
• key_pem and key_file

If cipher_suites is left blank, a safe default list is used. Refer to the Go Cipher Suites documentation for a list of supported cipher suites.

client_ca_file sets the ClientCA and ClientAuth to RequireAndVerifyClientCert in the TLSConfig. Refer to the Go TLS documentation for more information.

cors block

The cors block configures CORS settings for an HTTP server.

The following arguments are supported:

The allowed_headers argument specifies which headers are acceptable from a CORS request. The following headers are always implicitly allowed:

• Accept
• Accept-Language
• Content-Type
• Content-Language

If allowed_headers includes "*", all headers are permitted.

debug_metrics block

The debug_metrics block configures the metrics that this component generates to monitor its state.

The following arguments are supported:

disable_high_cardinality_metrics is the Grafana Alloy equivalent to the telemetry.disableHighCardinalityMetrics feature gate in the OpenTelemetry Collector. It removes attributes that could cause high cardinality metrics. For example, attributes with IP addresses and port numbers in metrics about HTTP and gRPC connections are removed.

level is the Alloy equivalent to the telemetry.metrics.level feature gate in the OpenTelemetry Collector. Possible values are "none", "basic", "normal" and "detailed".

output block

The output block configures a set of components to forward resulting telemetry data to.

The following arguments are supported:

You must specify the output block, but all its arguments are optional. By default, telemetry data is dropped. Configure the metrics, logs, and traces arguments accordingly to send telemetry data to other components.

Exported fields

otelcol.receiver.zipkin does not export any fields.

Component health

otelcol.receiver.zipkin is only reported as unhealthy if given an invalid configuration.

Debug information

otelcol.receiver.zipkin does not expose any component-specific debug information.

Example

This example forwards received traces through a batch processor before finally sending it to an OTLP-capable endpoint:

alloy Copy

otelcol.receiver.zipkin "default" {
  output {
    traces = [otelcol.processor.batch.default.input]
  }
}

otelcol.processor.batch "default" {
  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}

otelcol.exporter.otlp "default" {
  client {
    endpoint = sys.env("OTLP_ENDPOINT")
  }
}

Compatible components

otelcol.receiver.zipkin can accept arguments from the following components:

• Components that export OpenTelemetry otelcol.Consumer
