Simple remote system monitoring tool (lemmy.world)

I'm looking for a simple remote system monitoring and alerting tool. Nothing fancy. Do you know of any? Features:

monitors CPU, memory and disk space
can accept multiple hosts to watch
has some sort of alerting system
can be deployed as a single docker container
can be configured using a text file
configs can be imported and exported inside the docker compose file

I like uptime-kuma but it only records the uptime. Other containers I've found seemed to be overly complicated. They requires multiple docker containers for log aggregation etc...

There are some unofficial Nagios Docker setups, such as https://github.com/JasonRivers/Docker-Nagios
Here's their configuration doc: https://assets.nagios.com/downloads/nagioscore/docs/nagioscore/4/en/configmain.html
It isn't all that pretty, see some examples at https://sourceforge.net/projects/nagios/ , but it allows for email alerts, multiple hosts (including managed network devices) and monitoring CPU / Memory / Disk space.

I've only ever run it as a full VM so I can't give much thought on the docker container.
