Caution
Grafana Alloy is the new name for our distribution of the OTel collector. Grafana Agent has been deprecated and is in Long-Term Support (LTS) through October 31, 2025. Grafana Agent will reach an End-of-Life (EOL) on November 1, 2025. Read more about why we recommend migrating to Grafana Alloy.

Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.

otelcol.receiver.zipkin

Open source

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

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

Arguments

otelcol.receiver.zipkin supports the following arguments:

Name	Type	Description	Default	Required
`parse_string_tags`	`bool`	Parse string tags and binary annotations into non-string types.	`false`	no

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:

Hierarchy	Block	Description	Required
http	http	Configures the HTTP server to receive telemetry data.	no
http > tls	tls	Configures TLS for the HTTP server.	no
http > cors	cors	Configures CORS for the HTTP server.	no
output	output	Configures where to send received traces.	yes

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

http block

The http block configures the HTTP server used by the component.

The following arguments are supported:

Name	Type	Description	Default	Required
`endpoint`	`string`	`host:port` to listen for traffic on.	`"0.0.0.0:9411"`	no
`max_request_body_size`	`string`	Maximum request body size the server will allow. No limit when unset.		no
`include_metadata`	`boolean`	Propagate incoming connection metadata to downstream consumers.		no

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:

Name	Type	Description	Default	Required
`ca_file`	`string`	Path to the CA file.		no
`cert_file`	`string`	Path to the TLS certificate.		no
`key_file`	`string`	Path to the TLS certificate key.		no
`min_version`	`string`	Minimum acceptable TLS version for connections.	`"TLS 1.2"`	no
`max_version`	`string`	Maximum acceptable TLS version for connections.	`"TLS 1.3"`	no
`reload_interval`	`duration`	Frequency to reload the certificates.		no
`client_ca_file`	`string`	Path to the CA file used to authenticate client certificates.		no

cors block

The cors block configures CORS settings for an HTTP server.

The following arguments are supported:

Name	Type	Description	Default	Required
`allowed_origins`	`list(string)`	Allowed values for the `Origin` header.		no
`allowed_headers`	`list(string)`	Accepted headers from CORS requests.	`["X-Requested-With"]`	no
`max_age`	`number`	Configures the `Access-Control-Max-Age` response header.		no

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.

output block

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

The following arguments are supported:

Name	Type	Description	Default	Required
`metrics`	`list(otelcol.Consumer)`	List of consumers to send metrics to.	`[]`	no
`logs`	`list(otelcol.Consumer)`	List of consumers to send logs to.	`[]`	no
`traces`	`list(otelcol.Consumer)`	List of consumers to send traces to.	`[]`	no

The output block must be specified, but all of its arguments are optional. By default, telemetry data is dropped. To send telemetry data to other components, configure the metrics, logs, and traces arguments accordingly.

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:

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 = env("OTLP_ENDPOINT")
  }
}
