Fluent Bit Metrics

A plugin to collect Calyptia Fluent Bit's own metrics

PreviousExec WasiNextForward

Last updated 2 years ago

Calyptia Fluent Bit exposes its to allow you to monitor the internals of your pipeline. The collected metrics can be processed similarly to those from the . They can be sent to output plugins including , or ..

Important note: Metrics collected with Node Exporter Metrics flow through a separate pipeline from logs and current filters do not operate on top of metrics.

Simple Configuration File

In the following configuration file, the input plugin _node_exporter_metrics collects _metrics every 2 seconds and exposes them through our output plugin on HTTP/TCP port 2021.

# Calyptia Fluent Bit Metrics + Prometheus Exporter
# -------------------------------------------
# The following example collects Calyptia Fluent Bit metrics and exposes
# them through a Prometheus HTTP end-point.
#
# After starting the service try it with:
#
# $ curl http://127.0.0.1:2021/metrics
#
[SERVICE]
    flush           1
    log_level       info

[INPUT]
    name            fluentbit_metrics
    tag             internal_metrics
    scrape_interval 2

[OUTPUT]
    name            prometheus_exporter
    match           internal_metrics
    host            0.0.0.0
    port            2021

You can test the expose of the metrics by using curl:

curl http://127.0.0.1:2021/metrics
