No perfdata on a copied service

[Box293]

It has to be a bug in NSClient++ then. If you can't get performance data to work on the command line, then the NSClient is the issue.

I agree. What version of NSClient++ are you using?

[gormank]

I'll have to figure out how to get nsclient to tell me the version. I seem to recall the version installed had no version in the name, but that was last June.

I think I installled NSClient++-Stable-64.msi and it didin't work and NSClient++-Stable-64.msi was recomended and installed.

I'll have to figure out how to get nsclient to tell me the version.

Just run this:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H sqlhost

[gormank]

I sure made that difficult...

# /usr/local/nagios/libexec/check_nrpe -H sqlhost
I (0.4.3.143 2015-04-29) seem to be doing fine...

Can you run the following to see if we get performance data with the command you are using for only one drive?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H sqlhost-u -t 30 -c CheckDriveSize -a ShowAll=long MinWarnFree=10% MinCritFree=5% Drive=C

Please post the output.

# /usr/local/nagios/libexec/check_nrpe -H sqlhost -u -t 30 -c CheckDriveSize -a ShowAll=long MinWarnFree=10% MinCritFree=5% Drive=C

That is good. Checking one drive produced performance data. Can you run this below to check multiple drives to see if there is a limit in NSClient?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H sqlhost-u -t 30 -c CheckDriveSize -a ShowAll=long MinWarnFree=10% MinCritFree=5% Drive=C Drive=D Drive=G Drive=J Drive=L Drive=M Drive=N

You can add more drives until it fails outputting performance data.

[gormank]

Its no secret that a small number of drives produce perfdata, its stated in the thread. Its fine for the hundred or so boxes w/ 2 drives and an issue on the 6 that have ~7 or more. I'll check to see what number it starts not returning data...

Your command returned data.

Funny...

I found that the NSClient defaults to 1024 for payload length, but it can be increased.
Edit the nsclient.ini file and under this section
[/settings/NRPE/server]
Add this

Code: Select all

payload length=2048

Save the file and restart the NSClient service and let us know if this fixes it for you.

The output of this is 344 bytes and has no perfdata.
I can't really make changes to the system w/o a ton of electronic paperwork, meetings, and a 1.5 week lead time. Its insane, but true.

There's an old DOS command, subst that can be used to make pseudo drives from dirs on a drive. Maybe you could play a bit and see if it can be used to simulate a bunch of drives?

C:\>help subst
Associates a path with a drive letter.

SUBST [drive1: [drive2:]path]
SUBST drive1: /D

drive1: Specifies a virtual drive to which you want to assign a path.
[drive2:]path Specifies a physical drive and path you want to assign to
a virtual drive.
/D Deletes a substituted (virtual) drive.

Type SUBST with no parameters to display a list of current virtual drives.
