Problem with monitoring Windows 2012 R2 servers

[Frédéric GRANAT]

Hi,
Nagios XI version : Nagios XI 2012R1.6
Sometimes with CPU check launches CRITICAL alert whereas there's no overload with CPU.
This has been noticed especially on Windows 2012 R2 servers.

Rgds,

Frederic

Can we get a copy of one of the critical check results? Is there anything strange about what is being returned? Is it standard output that you would expect (besides the state that is being carried) or are they timing out? etc?

[sreinhardt]

What check are you using to monitor these systems? What values are you receiving when these do go critical? How often is this happening?

[Frédéric GRANAT]

Hi,
I'm using $USER1$/check_wmi_plus.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -m checkcpu -w $ARG3$ -c $ARG4$ $ARG5$

Display at the moment in Nagios XI
server1 CPU Usage 2h 7m 38s CRITICAL (Sample Period 26 sec) - [Triggered by _AvgCPU>90] - Average CPU Utilisation 100.00%

But if I run ./check_wmi_plus.pl -H server1 -u user -p pwd -m checkcpu -w 80 -c 90
OK (Sample Period 12 sec) - Average CPU Utilisation 5.62%|'Avg CPU Utilisation'=5.62%;80;90;

So Correct in command line and wrong in nagiosxi

If I perform a "Schedule an immediate check" in nagiosxi then it corrects the problem.
Seems to be a refresh problem

Rgds,

Frederic

Was it spiked at 100% throughout the entire 2 hour window prior to the immediate check? Could you show a screenshot of the graph over this period?

[Frédéric GRANAT]

Hi,
the graph is attached

Hi,
the graph is attached

It looks like you have not attached anything.

[Frédéric GRANAT]

I understand : The extension bmp is not allowed.
I attached it in jpeg format

This graph doesn't look right... How did you set up this check? Did you run the Windows WMI wizard? I can see on the graph that your check command is "check_win_cpu". Mine is "check_xi_service_wmiplus"... Go to the CCM->Services->View Text Config (the diskette icon) and show us the service config for the CPU Usage" (hide sensitive info). Also, show us the command definition of "check_win_cpu".
