I am using Nodequery and Nixstats. But they get data at certain intervals. So if anything happens in between that interval and my server went unresponsive or crashes then it’s not recorded. Now, it is very hard to detect what exactly caused the issue
Question 1: Can you suggest any self-hosted monitoring tool that very good at monitoring and alerting? Question 2: How to setup a system that can reboot Ubuntu if it goes out of memory.
