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…
