Server Monitoring with Munin and Monit on Debian 10
Author: Till Brehm • Tags: debian, monitoring • Comments: 8 • Updated: Jul 02, 2021In this article, I describe how you can monitor your Debian 10 server with munin and monit. munin generates graphs about almost every aspect of your server without much configuration, while monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action like a restart if it detects that a service is not behaving as expected. The combination of the two gives you complete monitoring: graphs that let you detect current or upcoming problems, and a watchdog that ensures the availability of the monitored services.
