Nagios Support Forum

Hi ,
In order to monitor windows service status, recently I added some monitors in my nagios application.
First I created a check command named check_win_service, the command use the check_nrpe script next I defined a service on every windows host, in these services I replace the variable $ARG1$ with the windows services I want to monitor, thus I didn't need to create multiple nagios services for every windows service, below is the example service list I used to replace $ARG1$: If there is no symbol '$' in the service name, the check result would be successful If there is '$' in service name, such as a MS SQL service with an instance name, the check result would be failed I guess this may be caused by variable replacement, but I am not a programmer, I don't know how to read the code to find the issue point.

Please give me some ideas or suggestions, thanks in advance for your help.

Regards,
Jun

As '$' is reserved for the shell, you will have to escape it. Try the following method, or you may have to use the resources.cfg file for strings containing a '$'.
1. Try adding a second dollar sign to the check: MSSQL\\\$$SQLEXPRESS
2. Resources: http://nagios.sourceforge.net/docs/3_0/configmain.html

What is the output from the failing check exactly?

It works, after I added a second dollar sign, the check result is successful. Very appreciate for your help! I have spent several days on this problem and almost no progress no it.

No problem. Escaping is tricky. Escaping in nagios is *very* tricky due to the potential for parsing through multiple shells. Enjoy the week!
