How to install Monit and Munin in Debian 8 / Nginx and configure in ISPConfig 3.1

I have seen some tutorials on HowtoForge about the installation of these two systems and I saw that ISPConfig has native support for them.
But the question is. Both systems run via Apache. If I use Nginx, can not I install them and configure them to monitor my VPS in ISPConfig?

 

It is possible and I actually use them both in my Ubuntu 16.04 + Nginx.

 

Steps to install Monit

Code:

$ sudo apt-get install monit

Configure Monit by

Code:

$ sudo vi /etc/monit/monitrc

Polling frequency (This is the interval (in seconds) at which Monit runs its tests.)

Code:

set daemon 120

Edit (Uncomment following)

Code:

set httpd port 2812 and
use address localhost  # only accept connection from localhost
allow localhost        # allow localhost to connect to the server 
allow admin:monit      # require user 'admin' with password 'monit'
allow @monit           # allow users group 'monit' to connect (rw)
allow @users readonly  # allow users group 'users' to connect (r)

Add monitoring service for Nginx

Code:

check process nginx with pidfile /var/run/nginx.pid
start program = "/etc/init.d/nginx start"
stop program = "/etc/init.d/nginx stop"

Check for syntax errors

Code:

$ sudo monit -t

When there are no errors and shows message like “Control file syntax OK“ then
Restart Monit

Code:

$ sudo /etc/init.d/monit restart

Verify Monit running by checking the logs

Code:

$ sudo tail -f /var/log/monit.log
