Which Open source monitoring tool(s) are you using?

[Andrew White]

Hello,

We use SolarWinds NPM with Netflow to monitor servers and networks, but my new bosses don't like the the continued cost of it every year and have asked me to look into open source variants.

These are what I've found out:

• Cacti

• Nagios Core

• Icinga (fork of Nagios)

• Zabbix + grafana

• LibreNMS (fork of Observium)

• Prtg (free)

• Prometheus + grafana
• Check_mk + grafana

I'm going to install a couple, but are there any I should give a miss and not waste my time on, or 1-2 I should absolutely give try?

What do you use?

Thanks

If you looking only netflow, i go with elastic search.
