The catch

Graphing-first, not alerting-first (thresholds/alerts need plugins like Thold), the PHP/RRDtool stack feels dated, and it does little autodiscovery — you build graph templates by hand.

The honest take

If you still run Cacti, you run it for the bandwidth graphs and you know exactly why. For anything new, LibreNMS gives you Cacti’s graphs plus alerting and autodiscovery.
