Beginner installing plugins


I just installed Nagios on a Suse server. I have many Windows server that I installed nsclient++ on. I am happy with the results and able to see all the nsclients. I do want more monitors then their “default” package.

I browse the Exchange and very delighted on all the plugins I see, but the only problem, is that I do not know how to go about installing them.

If you help me, please keep in mind that I am a novice on Linux, but can do anything told in detail.

So far I ran into files without instructions to install. (maybe it is very easy as dumping into a directory thats why there are not instructions) I fould a .sh file (which I do not know what to do with) and a check_ file that I dumped into the libexec directory which did not work.

Thanks in advance!


the best thing is to start with searching for documentations on nsclient++.
NSClient is able to access all data available in the windows perormance monitor so you would usually not need any more plugins to make most of what you possibly want to do.

If you say exactly WHAT you want to check on the windows server it’s easier you get a useful answer.


I am currently monitoring:

Hi Neeper67,

Were you able to configure the new plugins? I’m also in the same situation. Please let me know briefly the steps you followed to configure the new plugins. For example to configure CheckEventLog, what are the steps required on the Nagios server and the NSClient++ on the monitored windows machine.



I am new to this but I just managed to install check_mssql from … ql/details

Installing a plugin basically involves:

  1. download plugin
  2. copy it to /usr/local/nagios/libexec
  3. Change owner to nagios and make it executable
  4. installing dependencies. In my case on Ubuntu:
    sudo apt-get install php5 php5-mysql php5-cli libapache2-mod-php5 php5-sybase
