NCPA 1.7.2 CPU 100%

Post by AMacintosh »

We are seeing an incorrect CPU Usage result on a Windows 2008 R2 server. It keeps reporting 100% CPU usage however the server perf mon log and Task Manager do not show this issue. When I look at the Top Processes tab in the agent on that server, it keeps flashing CPU Load: 100%. If at the same time, I have task manager open, I don't see this spike. There only appears to be one CPU on this VM.

Can you run the following commands and show us the output?

On the Windows box (from the CMD)

Code: Select all

wmic cpu get loadpercentage
On the Nagios XI server (from the CLI)

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H <client ip> -t 'token' -P 5693 -M cpu/percent -w 80 -c 90

Please see the results...

Load Percentage
5

[]# /usr/local/nagios/libexec/check_ncpa.py -H 10.0.0.0 -t 'token' -P 5693 -M cpu/percent -w 80 -c 90
CRITICAL: percent was 100% | 'percent_0'=100%;80;90;
[]# /usr/local/nagios/libexec/check_ncpa.py -H 10.0.0.0 -t 'token' -P 5693 -M cpu/percent -w 80 -c 90
OK: percent was 2% | 'percent_0'=2%;80;90;

So, the first check "failed", but the second one didn't. What is the output when you try to increase verbosity?

Code: Select all

/usr/local/nagios/libexec/check_ncpa.py -H 10.0.0.0 -t 'token' -P 5693 -M cpu/percent -w 80 -c 90 -vvv
What is the value that you see in the API?

Code: Select all

https://clientip:5693/api/cpu/percent
Can you upload the "ncpa_listener.log" from the Windows box, so that we can take a look at it?

I ran the checks immediately right after each other and it shows that the value for CPU load is flapping between 100%. I'll check the API and the command line check with -vv and get back to you.

Please see the results of 3 fast command line checks.

[root@nastisrnagap01 ~]# /usr/local/nagios/libexec/check_ncpa.py -H 10.0.0.0 -t 'token' -P 5693 -M cpu/percent -w 80 -c 90 -vvv
CRITICAL: percent was 100% | 'percent_0'=100%;80;90;

The API is showing either 0% or 100% when refreshing.

Ideas?

Edit: NCPA listener log

Were you trying to attach your log? Does not look like it got through.
