I am a beginner in icinga and nagios usage for server management. I setup icinga on a machine and set up all the basics. The next step I tried was to check if certain services were running at ports 8080, 8081 and 8082 or not. I wrote a quick python script for that. I placed that file under /usr/local/lib/myscript.py. The next step I did was to create a command under /etc/nagios-plugins/config/testone.cfg . My command looks like this

define command{
        command_name    check_restarts
        command_line    python /usr/local/lib/myscript.py -w 3 -c 5 -p 8080
        command_line    python /usr/local/lib/myscript.py -w 3 -c 5 -p 8081
        command_line    python /usr/local/lib/myscript.py -w 3 -c 5 -p 8082
        }

I then added a service to services.conf under /etc/icinga2/conf.d/services.conf. But this leads to an error when I restart icinga which shows up a message Backend icinga not running on the UI and errors point to services.conf when I try sudo service icings2 status.

Can anyone please guid me around these steps?

Don't get confused with Icinga and Icinga2. They are different tools. Icinga2 configuration format is different from Icinga and Nagios. So there is a big change in configuring objects in icinga2. See the official migration doc: URL

So for your case, you need to use CheckCommand instead of command. Also service definition needs to be changed.

All config files are inside /etc/icinga2 dir and Plugin dir should be defined inside /etc/icinga2/constants.conf file.

check Icinga2 config files for syntax errors before restart/reload with command: /etc/init.d/icinga2 checkconfig

A nice way to get some more information is to run this command: icinga2 daemon -C. It does pretty much the same as /etc/init.d/icinga2 checkconfig pointed out by 7171u.
