How to monitor influxdb

[KervyN (Boris)]

Dear community,

is there a plugin available to monitor an influxdb?

When searching for check_mk and influxdb I only get articles that tell me how to integrate check_mk and influxdb, but not HOW to monitor the influxdb with check_mk.

Does someone got a plugin handy?

Write your own plugin. That should be quite easy for the whitespace separated metrics format from the HTTP endpoint /metrics. Start with an agent plugin on the database server that basically pipes the output of this endpoint into a section in the monitoring output:

#!/bin/bash
echo '<<<my_influx>>>'
wget -O - http://127.0.0.1:1234/metrics

Writing a plugin for the Checkmk side is documented here: Writing your own check plug-ins
I wrote a programming example that should be easily adaptable for the metrics you need to pull from the output:
checkmk-snippets/mkp/helloworld at main · mschlenker/checkmk-snippets · GitHub
It uses exactly the same space separated format as input, so just install the Hello world! MKP and start adjusting and extending it for the required Influx parameters.
