You can install the monit package from the official Ubuntu repositories by issuing the following command: sudo apt install monit Login to your VPS via SSH ssh _server Install Monit This guide should work on other Linux VPS systems as well but was tested and written for an Ubuntu 16.04 VPS. With Monit you can also monitor your network connections, CPU usage, RAM memory load average and much more. You can use Monit to stop or restart your web server if it is using too much resources, to monitor daemon processes, to monitor files, directories and get an email alert or perform a predefined action if they change. Monit is an open source tool for monitoring and managing, processes, files, directories and file systems on a UNIX system.

Config-specific variables have been redacted and are marked with %%%. I'm not sure I would choose it if I needed super-duper uptime or detailed stats, but for my purpose it is good enough. IMO, monit's greatest advantages are that it is relatively simple and light.
