Server Monitoring with Munin and Monit on Debian 10
Author: Till Brehm • Tags: debian, monitoring • Comments: 8In 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.
