I want something that has a WebUI, can show in a graph like the CPU and RAM graph for this day and maybe some days before. Also I would like to view what was running at any given time (I mean from 2-3 days before to now).
Is there any (FOSS) software that does that?
Thanks.
I think prometheus + grafana might be what you are looking for. In combination with loki grafana can also be used for viewing log messages.
Absolutely this, nothing else is required. Well, maybe alertmanager if you want to receive alerts
Do both have to run on the host machine or can a remote machine execute the probes (over ssh or something).
I like munin, it’s very limited, a bit hard to configure and doesn’t have many features but uses almost no resources
Zabbix?
I use Check_MK
Same here. I still don’t understand why everyone is about Grafana. I’ve tested it and checkMK is more… Everything.
Switched from CMK to Zabbix at my previous job. Zabbix is far more comfortable and has all the same possibilities that CMK has. But you can setup everything in the web GUI and don’t need to reload anything.
+1 for CMK. It’s built on nagios. Been using it for decades. That shit is rock solid and has never let me down.
Prometheus is metrics and grafana reports it. IMHO, better reporting and graphing, better eye candy. But also harder to setup and get right.
CMK agent works on 95% of what you want with just the agent.
Can’t really go wrong with the old school nagios+thruk. The learning curve is a tad steep but it teaches you a lot of things about your systems.
