Documentation Grafana Agent Grafana Agent Flow Reference Components otelcol.exporter.otlp

otelcol.exporter.otlp

otelcol.exporter.otlp accepts telemetry data from other otelcol components and writes them over the network using the OTLP gRPC protocol.

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

Multiple otelcol.exporter.otlp components can be specified by giving them different labels.

Usage

Alloy Copy

otelcol.exporter.otlp "LABEL" {
  client {
    endpoint = "HOST:PORT"
  }
}

Arguments

otelcol.exporter.otlp supports the following arguments:

Blocks

The following blocks are supported inside the definition of otelcol.exporter.otlp:

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

client block

The client block configures the gRPC client used by the component.

The following arguments are supported:

The balancer_name argument controls what client-side load balancing mechanism to use. See the gRPC documentation on Load balancing for more information. When unspecified, pick_first is used.

An HTTP proxy can be configured through the following environment variables:

• HTTPS_PROXY
• NO_PROXY

The HTTPS_PROXY environment variable specifies a URL to use for proxying requests. Connections to the proxy are established via the HTTP CONNECT method.

The NO_PROXY environment variable is an optional list of comma-separated hostnames for which the HTTPS proxy should not be used. Each hostname can be provided as an IP address (1.2.3.4), an IP address in CIDR notation (1.2.3.4/8), a domain name (example.com), or *. A domain name matches that domain and all subdomains. A domain name with a leading “.” (.example.com) matches subdomains only. NO_PROXY is only read when HTTPS_PROXY is set.

Because otelcol.exporter.otlp uses gRPC, the configured proxy server must be able to handle and proxy HTTP/2 traffic.

tls block

The tls block configures TLS settings used for the connection to the gRPC server.

keepalive block

The keepalive block configures keepalive settings for gRPC client connections.

The following arguments are supported:

sending_queue block

The sending_queue block configures an in-memory buffer of batches before data is sent to the gRPC server.

retry_on_failure block

The retry_on_failure block configures how failed requests to the gRPC server are retried.

Exported fields

The following fields are exported and can be referenced by other components:

input accepts otelcol.Consumer data for any telemetry signal (metrics, logs, or traces).

Component health

otelcol.exporter.otlp is only reported as unhealthy if given an invalid configuration.

Debug information

otelcol.exporter.otlp does not expose any component-specific debug information.

Example

This example creates an exporter to send data to a locally running Grafana Tempo without TLS:

Alloy Copy

otelcol.exporter.otlp "tempo" {
    client {
        endpoint = "tempo:4317"
        tls {
            insecure             = true
            insecure_skip_verify = true
        }
    }
}
