Monitor Disk Usage of Windows Mount Points...

[Box293]

To add to what @tgriep has provided, I did some tests and it appears as though you need at least NSClient 0.4.2.x versions onwards to be able to check mount points.

Once you have the updated version it will be checked it by default:

Code: Select all

Command:
check_nrpe -H win2008r2-01 -c CheckDriveSize

Output:
OK All 6 drive(s) are ok|'C:\ used'=19.01372GB;47.9203;53.91034;0;59.90038 'C:\ used %'=31%;79;89;0;100 'D:\ used'=0B;0;0;0;0 'E:\ used'=0.08886GB;31.99765;35.99736;0;39.99706 'E:\ used %'=0%;79;89;0;100 'Q:\ used'=0.0884GB;19.99765;22.49736;0;24.99706 'Q:\ used %'=0%;79;89;0;100 '\\?\Volume{791a0772-737e-11e4-98ac-806e6f6e6963}\ used'=29.19921MB;79.99687;89.99648;0;99.99609 '\\?\Volume{791a0772-737e-11e4-98ac-806e6f6e6963}\ used %'=29%;79;89;0;100 'C:\Mounted Disks\A Mounted Disk\ used'=0.08816GB;14.39765;16.19736;0;17.99706 'C:\Mounted Disks\A Mounted Disk\ used %'=0%;79;89;0;100

Or you can target it specifically:

Code: Select all

Command:
check_nrpe -H win2008r2-01 -c CheckDriveSize -a Drive='C:\Mounted Disks\A Mounted Disk'

Output:
OK All 1 drive(s) are ok|'C:\Mounted Disks\A Mounted Disk used'=0.08816GB;14.39765;16.19736;0;17.99706 'C:\Mounted Disks\A Mounted Disk used %'=0%;79;89;0;100

Sorry for the delay, been putting out fires.
Here is the output to get the version...

I (0,4,1,105 2014-04-28) seem to be doing fine...

Looks like you need to upgrade.

[jasonlehman]

Ok, I've updated to...

NSClient++ 0.4.3.143 2015-04-29

I also don't think the check_nrpe plugin is installed on my Nagios server.
Shouldn't it be listed here?

Code: Select all

[root@nagios objects]# cd /usr/local/nagios/libexec/

[jasonlehman]

I just found the check_nrpe in /usr/lib64/nagios/plugins/

Sorry for the confusion.

What happens when you try checking now? Did the upgrade fix it?

[jasonlehman]

I was just about to post the results.

I can get results running this...

Code: Select all

[root@nagios plugins]# ./check_nrpe -H xxx.xxx.xxx.xxx -c CheckDriveSize
OK All 5 drive(s) are ok|'C:\ used'=37.26652GB;43.99843;49.49823;0;54.99804 'C:\ used %'=67%;79;89;0;100 'E:\ used'=25.4375MB;197.54999;222.24375;0;246.9375 'E:\ used %'=10%;79;89;0;100 'E:\SQL\Logs\ used'=5.08654GB;59.9976;67.4973;0;74.997 'E:\SQL\Logs\ used %'=6%;79;89;0;100 'E:\SQL\TempDatabases\ used'=1.98883GB;27.9976;31.4973;0;34.997 'E:\SQL\TempDatabases\ used %'=5%;79;89;0;100 'E:\SQL\Databases\ used'=74.58734GB;239.9976;269.9973;0;299.997 'E:\SQL\Databases\ used %'=24%;79;89;0;100

I cant get results w/ -a option...

Code: Select all

[root@nagios plugins]# ./check_nrpe -H xxx.xxx.xxx.xxx -c CheckDriveSize -a Drive='E:\SQL\Databases'
Exception processing request: Request contained arguments (not currently allowed, check the allow arguments option).

So now, I need to figure out how to check each mounted volume listed above; is healthy & how much free space is there.
I'm guessing I'll have to add a command in the commands.cfg
and then add a servce definition in my windows.cfg
That's where I'll need some help, please.
Thanks.

How about adding the following somewhere in your nsclient.ini:

Code: Select all

[/settings/NRPE/server]
allow arguments = true

[jasonlehman]

I added that to the nsclient.ini & restarted the NSClient++ service.

I then got different results, but not what we wanted. Am I typing in the wrong syntax?

Code: Select all

[root@nagios plugins]# ./check_nrpe -H xxx.xxx.xxx.xxx -c CheckDriveSize -a Drive='E:\SQL\Databases\'
Exception processing request: Request command contained illegal metachars!

[jdalrymple]

In the section:

Code: Select all

[/settings/NRPE/server]

add:

Code: Select all

allow nasty characters = true
