snmp_exporter VS checkmk

It is kind of described here:https://github.com/prometheus/snmp_exporter/issues/405

The SNMP exporter can do lookups. Take a look at this documentation.

wget https://github.com/prometheus/snmp_exporter/releases/download/v0.21.0/snmp_exporter-0.21.0.linux-amd64.tar.gz

You need to find the OSBs for the router, and add those to the explorer. Take a look at this doc: https://github.com/prometheus/snmp_exporter/blob/main/generator/README.md

You can fetch this metrics using the SNMP exporter https://github.com/prometheus/snmp_exporter

As a maintainer of the Prometheus SNMP exporter, and the defacto standard implementation of SNMP in Go, I can tell you exactly how convoluted SNMP is at a protocol and specification level.

Refer to https://github.com/prometheus/snmp_exporter and https://blog.paessler.com/how-to-enable-snmp-on-your-operating-system

For example, you can use unpoller to bring your unifi stuff into the same system as your SNMP data.

SNMP by itself is a rather crude protocol, with values being identified as OID (Object IDs). Those are numerical identifiers. A MIB-File contains the information on how to translate these OIDs into workable data. There is some information on how to feed these files to the exporter located here: https://github.com/prometheus/snmp_exporter/tree/main/generator

CheckMK - GitHub

CheckMK https://checkmk.com. You can spin this up in a docker container

I use CheckMK to do all of this and more, except nutanix. But checkmk also can Monitor nutanix via the "Nutanix Prism" special agent Integration

BI machine and NVR report to CheckMK Raw host so it's easy to see historic stats.

I’m using https://checkmk.com/ to monitor stuff and it seems to work great. Lots of built in features and functions and if they don’t have what you need you can also create custom scripts to check and report on anything you can dream up. Runs great in docker (I’m using portainer but will run fine in plain old docker).

Have a look at CheckMK open source version is really good, you can spin it up in a docker container and is relatively easy to get some initial monitors going. As to whether it's worthwhile, I guess it depends how much you want to know how you servers are doing and when something goes wrong.

Checkmk

checkmk: https://checkmk.com/

Checkmk I have use the "raw" (free) version and we now use the enterprise version. Both are very capable.
