cadvisor VS LibreNMS

cAdvisor

https://github.com/google/cadvisor exports Prometheus metrics, but also offers a simple web-ui for container metrics.

For CPU and memory metrics, you can use cAdvisor to collect container level data.

Perhaps https://github.com/google/cadvisor + prometheus (or influx or whatever else) + grafana?

We could have used a much more focussed tool like Prometheus or Cadvisor to gather system stats, but that is not the main objective of this article.

Result: Interestingly, the GitHub Issue that talks about cAdvisor and Docker Desktop for Mac for running cAdvisor is still open and not fixed.

If you're running things under systemd, you can enable process accounting and use cAdvisor.

Bug report is over here

I playing with LibreNMS in my lab, just for the heck of it.

git clone https://github.com/librenms/librenms.git

LibreNMS is awesome! It's a fork of Observium, but has a more "friendly" development philosophy—there's some history there.

- NMS / NPM: NetXMS, Zabbix, LibreNMS, PRTG - NCM, updates, automation: Unimus - IaC / automation: Ansible - DCIM / IPAM: NetBox - IPAM / DDI: Infoblox

However, you can try your luck with a more "all-in-one" like LibreNMS that includes a lot of stuff and quite an amount of integrations (like sflow, snmp, checkmk, etc...) which is probably what you're looking (the all in a single screen)

take a look at snmp and librenms https://www.librenms.org/ I have been using this for years and it has never let me down. You can even then import data into Grafana if you want.
