Monitor Disk Usage of Windows Mount Points...

[hsmith]

The reason that your command is failing is because...

Code: Select all

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

Inside of here $USER1$ is pointing at /usr/local/nagios/libexec since it is defined in resource.cfg as pointing at that.

You need to either move check_nrpe or change the command_line part of the command.

Make sense?

Make's perfect sense. I changed the command_line to point to the correct path; which is for me /usr/lib64/nagios/plugins/
I'm not sure why mine is different.

I now need to understand how to put in the correct path to the mount point in the check_command.
Using what was suggested... check_mp!CheckDriveSize!E:\SQL\Databases!!!!!!

I now get this result from Nagios...
Filter processing failed: Error: Failed to get size for: 3: The system cannot find the path specified.

Do I really need 6 exclamation points after my path? I'm not sure why there are so many.
Thanks

I wouldn't touch the exclamation points. Instead, what I would try to do is move/copy your check_nrpe over to /usr/local/nagios/libexec and put $USER1$ back in place instead of the file path. We could be running into some weird issue with having a path there instead of $USER1$.

Try this and let me know, thanks!

Ok, so I copied my check_nrpe to /usr/local/nagios/libexec/
So it's now in two locations

Code: Select all

[root@nagios objects]# find / -name check_nrpe
/usr/lib64/nagios/plugins/check_nrpe
/usr/local/nagios/libexec/check_nrpe

Modified the command back to use $USER1$/check_nrpe

Code: Select all

# 'check_mp' command the community helped me make to check Windows Mount Points via check_nrpe
define command {
       command_name     check_mp
       command_line     $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$
}

I then restarted the Nagios service.
Unfortunately, I still get the message...
Filter processing failed: Error: Failed to get size for: 3: The system cannot find the path specified.

BTW here is the service

Code: Select all

#windows Mount Point for SQL Databases on host1
define service {
        host_name                       host1
        service_description             SQL DB Disk
        use                             generic-service
        check_command                   check_mp!CheckDriveSize!E:\SQL\Databases!!!!!!
        check_period                    24x7
        register                        1
        }

Hmm... let's put that $ARG2$ in quotes. '$ARG2'

[jasonlehman]

Hmm... let's put that $ARG2$ in quotes. '$ARG2'

That worked, now I get the result of...

OK All 1 drive(s) are ok

Thank you

What does it me by all drives are ok? Will this alert me if the drive starts to get full, like the check_nt!USEDDISKSPACE! will alert at warning & critical values?
If so, is there a way to set the warning & critical values?
Thanks

./check_nrpe -H x.x.x.x-c CheckDriveSize -a Drive=D: MinCritFree=20% MinWarnFree=30%

Is the command I used for this. MinWarnFree is the minimum amount free before it warns you, MinCritFree is the amount before it goes critical. You can modify your service check to include these.

[jasonlehman]

Would I just add MinCritFree=20% MinWarnFree=30% to the service is setup?

I tried a few different ways, but dont get any different results.

I have...

Code: Select all

#windows Mount Point for SQL Databases on host1
define service {
        host_name                       host1
        service_description             SQL DB Disk
        use                             generic-service
        check_command                   check_mp!CheckDriveSize!E:\SQL\Databases!!!!!!-a MinCritFree=10% MinWarnFree=15%
        check_period                    24x7
        register                        1
        }

        register                        1
        }

Close. Add it after the Databases portion. Like so:

Code: Select all

#windows Mount Point for SQL Databases on host1
define service {
        host_name                       host1
        service_description             SQL DB Disk
        use                             generic-service
        check_command                   check_mp!CheckDriveSize!E:\SQL\Databases MinCritFree=10% MinWarnFree=15%!!!!!!
        check_period                    24x7
        register                        1
        }

And try.

[jasonlehman]

I'm back to the error...
Filter processing failed: Error: Failed to get size for: 3: The system cannot find the path specified.

When I put it in the exclamation points...

Code: Select all

#windows Mount Point for SQL Databases on host1
define service {
        host_name                       host1
        service_description             SQL DB Disk
        use                             generic-service
        check_command                   check_mp!CheckDriveSize!E:\SQL\Databases MinCritFree=10% MinWarnFree=15%!!!!!!
        check_period                    24x7
        register                        1
        }

        register                        1
        }

There needs to be a Drive= there, I may have screwed that one up.

        }

[jasonlehman]

No worries.
Unfortunately, that didn't work either.
Getting...
