Fluent Bit Metrics

A plugin to collect Calyptia Fluent Bit's own metrics

PreviousExec WasiNextForward

Last updated 11 months 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.

Description
Default

scrape_interval

The rate at which metrics are collected from the host operating system

2 seconds

scrape_on_start

Scrape metrics upon start, useful to avoid waiting for 'scrape_interval' for the first round 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
