Memory Reporting

[greyclear]

Trying to set this up http://www.nsclient.org/nscp/wiki/CheckSystem/checkMem

This is my windows.cfg

Code: Select all

define service{
       use     generic-service
       host_name               STLSMS
       service_description   Memory Usage
       check_command      check_nrpe!checkMem
       }

But how do I define the service?

I see it works from the command line
[root@nagios var]# /usr/lib64/nagios/plugins/check_nrpe -H stlsms -p 5666 -c CheckMEM -a MaxWarn=80% MaxCrit=90% ShowAll type=physical
WARNING: physical memory: Total: 8G - Used: 7.01G (87%) - Free: 0.987G (13%) > warning|'physical memory %'=87%;80;90 'physical memory'=7.00999G;6;7;0;8

I have to assume that your nrpe.cfg file is accepting arguments. Define your service as follows:

Code: Select all

define service{
       use     generic-service
       host_name               STLSMS
       service_description   Memory Usage
       check_command      check_nrpe!checkMem!MaxWarn=80% MaxCrit=90% ShowAll type=physical
       }

Note that the arguments to an NRPE command are all sent as one argument through NRPE to the other side.

Into what file does this go? This is the confusing part do I have to define each host/service for this? For example if I have 44 servers I am checking, that is 44 extra lines I will have to add to the templates.cfg or services.cfg

[eloyd]

The only difference between what I wrote and what you already have is the addition of the "!MaxWarn=80% MaxCrit=90% ShowAll type=physical" to the end of your command line in your windows.cfg file.

Yes, you need to add this to each host that you want to monitor this way, but it sounds like you might benefit from some basic Nagios training to get a feel for what files are used where. If that's the case, please look at http://nagios.sourceforge.net/docs/3_0/quickstart.html and focus on the sections at the bottom called "Monitoring Windows machines" and "Monitoring Linux/Unix machines."

Gotcha, I'm already part of the way in I just happened to notice that the memory checking was incorrect using check_nt command so I googled around and found this was more efficient. But when I added it like you stated and that is what I gathered from searching, I need to define it somewhere. Disregard the pervasive warning

Code: Select all

     Check your configuration file(s) to ensure that they contain valid
     directives and data defintions.  If you are upgrading from a previous
     version of Nagios, you should be aware that some variables/definitions
     may have been removed or modified in this version.  Make sure to read
     the HTML documentation regarding the config files, as well as the
     'Whats New' section to find out what has changed.

Put the stuff in quotes. If that doesn't fix it, we'll need to delve deeper into your configurations, and I'm about to head out for the day.

Code: Select all

check_command      check_nrpe!checkMem!"MaxWarn=80% MaxCrit=90% ShowAll type=physical"

Can you show us the check_nrpe command you have defined in commands.cfg? Something may be getting caught up there.

[greyclear]

I don't have any check_nrpe in my commands file

[eloyd]

Well, there's your problem.

You need to define something in commands.cfg that looks like this:

Code: Select all

define command{
        command_name    check_nrpe
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a "$ARG2$"
}
