Cluster Service Check Fails

Nagios Core 4.3.4
Windows 2012 R2 Clustered SQL Server

My check

Code: Select all

# 'check service cluster' command definition
define command{

    command_line        /usr/local/nagios/libexec/check_cluster --service -l $ARG1$ -w $ARG2$ -c $ARG3$ -d $ARG4$
}

This was working fine had a power outage last night and after the servers came up I got this error
Any ideas?

Thank you

It thinks 2 of these are in an Unknown state

Code: Select all

$SERVICESTATEID:TGCS014-N1:MSSQLSHAREPOINT$,$SERVICESTATEID:TGCS014-N2:MSSQLSHAREPOINT$

Can you show the current state for the following HOST:SERVICE

Code: Select all

TGCS014-N1:MSSQLSHAREPOINT
TGCS014-N2:MSSQLSHAREPOINT

That's what I was thinking also but looking at this I am puzzled.

Can you show the current state for the following HOST:SERVICE

How do I do that? cluster power shell command? if so which one

[scottwilkerson]

In nagios core, search for
MSSQLSHAREPOINT

Show the results

[kwhogster]

Searching for MSSQLSHAREPOINT in Nagios Core

results 1- 0 of 0 Matching Services

Well that is likely the problem.

The cluster check, is checking the status of each of these services, and it looks like they don't exist

[kwhogster]

Where should they exist?

[scottwilkerson]

Where should they exist?

In your nagios configuration files

[kwhogster]

Did you review my service check in my first posting?

That is the only place I have the definition located.


also do you know of a way I can manually check this ?

Yes I did, I also understand exactly how check_cluster works. It takes the arguments you pass as $SERVICESTATEID:TGCS014-N1:MSSQLSHAREPOINT$,$SERVICESTATEID:TGCS014-N2:MSSQLSHAREPOINT$ and extrapolates the values...

The macro $SERVICESTATEID:TGCS014-N1:MSSQLSHAREPOINT$ means to grab the SERVICESTATEID from the service MSSQLSHAREPOINT on the host TGCS014-N1 in nagios. This must be present.
