telemetry

Telemetry

The purpose of this package is to provide a way to easily integrate OpenTelemetry Protocol (OTLP) metrics collection into a Tendermint 2 node.

Configure Telemetry

Telemetry can be regularly configured within the TM2 node through the [telemetry] section. It is disabled by default.

OTEL configuration

There are many ways configure the OTEL pipeline for exporting metrics. Here is an example of how a local OTEL collector can be configured to send metrics to Grafana Cloud. This is an optional step and can be highly customized.

OTEL collector

The latest collector releases can be found here. This is an example of the config that can be used to receive metrics from gno.land and publish them to Grafana Cloud.

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317 # should be the same as the TELEM_EXPORTER_ENDPOINT variable

processors:
  batch:

exporters:
  otlphttp:
    endpoint: https://otlp-gateway-prod-us-east-0.grafana.net/otlp

service:
  pipelines:
    metrics:
      receivers: [ otlp ]
      processors: [ batch ]
      exporters: [ otlphttp ]

Collector exporter environment variables, including those for authentication, can be found here.
