OpenTelemetry

An output plugin to submit Logs, Metrics, or Traces to an OpenTelemetry endpoint

The OpenTelemetry plugin allows you to take logs, metrics, and traces from Calyptia Fluent Bit and submit them to an OpenTelemetry HTTP endpoint.

Important Note: At the moment only HTTP endpoints are supported.

Getting Started

The OpenTelemetry plugin works with logs and only the metrics collected from one of the metric input plugins. In the following example, log records generated by the dummy plugin and the host metrics collected by the node exporter metrics plugin are exported by the OpenTelemetry output plugin.

# Dummy Logs & traces with Node Exporter Metrics export using OpenTelemetry output plugin
# -------------------------------------------
# The following example collects host metrics on Linux and dummy logs & traces and delivers
# them through the OpenTelemetry plugin to a local collector :
