SNMP Monitoring for over 40 firewalls looking to replace a standing Cacti server

Hi all,

Just looking to get pointed in the right direction here then I can figure out the rest from there

We currently use Cacti to monitor our firewalls and it works great...it's just a bit dated.

I was looking at setting up a Grafana, InfluxDB, and Telegraf stack to replace our Cacti server but it seems that is more for singular networks.

Does anyone have suggestions on what kind of stack I should be looking at for SNMP polling (the reason I need polling vs traps is the sites I need to monitor typically don't have a spare machine that I can set up an agent on).

Or am I just misunderstanding Telegraf and Influx and it can indeed support many hosts? Or should I be looking at something line snmpcollector?

I tried a Grafana, Zabbix, MySQL stack, but was running into configuration issues.

​

Any and all help is greatly appreciated!
