If you’re using the excellent netdata for server monitoring and want to stick the data in a database for long-term storage and pretty graphs, this generally works. If you’re feeling fancy, you can set up retention policies in InfluxDB – this post assumes you’ve already got a working InfluxDB + Grafana stack set up somewhere. Kudos to this blog post, which is referenced by the netdata documentation.
Add this section to your
netdata.conf file, replacing
$INFLUXDB with a more relevant IP address:
[backend] host tags = $TAG enabled = yes data source = average type = opentsdb destination = tcp:$INFLUXDB:$PORT prefix = $PREFIX hostname = $HOSTNAME update every = 10 buffer on failures = 10 timeout ms = 20000 # send names instead of ids = yes # send charts matching = *
Over on your InfluxDB server, make a database for all this data to end up in, and make sure you’ve got an OpenTSDB listening service in
[[opentsdb]] enabled = true bind-address = ":$PORT" database = "opentsdb"
Once you’ve restarted both services, netdata should be happily filling your InfluxDB server with data. You can grab an example Grafana dashboard in JSON format here – just be sure to replace
$PREFIX with the prefix you set in the netdata config file, and
$HOSTNAME with the hostname. It should start showing data immediately.
