Netdata, monitoring a few thousand servers (virtual) that way.

Prometheus + Grafana, the same I use at my job.

Just to make sure: You are aware that a search option here exists, yes? And you keep refusing to use it for whatever reason?

Observium…

If it’s just one server, Netdata is a better option…

Nagios for service/QOS, Grafana for dashboarding for some items more specific. Planning on eventually switching to zabbix but nagios is so simple that i feel having a hard time justifying moving over 400 monitored services to it

If its down, I assume performance is bad

I came across monit recently, seems nice

Its not well liked but I use nagios core for alerts and jump to grafana which has data in prometheus, influxdb, and mysql backend for trends like cpu usage hard drive Temps etc.

None. There is no need for a performance monitor for my home lab. I just have an alert if one of my main three services is down. That is all i need.

I use Uptime Kuma to monitor particular services and NetData for server performance. I then pipe the alerts through to Pushover

libreNMS is the tool I use, and it connects to systems primarily via SNMP (use v3, do not use v1 or v2c).

Netdata, I’ve meant to look into Grafana but it always seemed way too overcomplicated and heavy for my purposes. Maybe one day, though…

InfluxDB metrics server and Telegraf agent to collect metrics

I know that it needs a fix when my dad complaining that he can’t watch TV and the rolling door doesn’t open in the morning.

We use zabbix here. Zabbix is amazing and we put it in all of our templates so any new servers and hosts pop up on zabbix dashboard preconfigured just like that. For logs and security we use an Elastik “ELK stack” which gives us a heads up if anything is wrong in the logs, and zabbix gives us a head up of the systems health all together. Between the two, our health monitor panel combines the two windows so we can see full server health and any problems right there as a todo list for the IT team
