Building out an InfluxDB host for metrics collection is pretty straightforward, even piping things into it from various sources isn’t difficult, thanks to the multitude of plugins available out of the box, including some very handy SNMP gathering that I’ll likely go into later when the mood strikes and I have more time. I did exactly this at the day gig not long ago to replace the bulky, somewhat cumbersome check_mk based monitoring I initially set up when I started here (they had nothing in place, except for a few broken zabbix clients, no collection point).
