cpu performance graph is not showing in nagios xi

[Gonela]

Hi team,

We enable the cpu monitoring , for this we are not able to get the cpu performance graph. We have seen the CPU rrd file for respective The rrd file update last jan 10 after jan 10 the file is not update. We have seen that the CPU is continuous flapping from few days. What is the reason for to does not get the performance graph.

Is nagios will stop the notification and performance graph while host/service is in between flapping.

Is the service still flapping?

Here is our performance graph troubleshooting doc.

If you can post the command outputs and debug logs that would help!

Thanks.

Hi team,

how to know from how long the service is flapping i mean from which date/time.

Yes still the service is under flapping.


which command output details you need and where should i find it and what is the path of the debug logs. so that we can provide you.

Could you show me this screenshot of your CPU service Advanced status detail in XI GUI? (Please send me something like this)

Capture.PNG

Could you also send us your Nagios XI profile?

How to get the Nagios XI Profile --> Go to the XI Home Page click "Admin" > "System Profile" --> "Download Profile" button
Save the profile.zip file and upload it here or PM me.

If you receive a PROFILE BUILD FAILED
Please follow this article,

https://support.nagios.com/kb/article.p ... ategory=44

After you PM the profile please update this thread so we can see it on our end, unless you post the profile on here. Thanks

Hi team,

Please find the attachment. We can't provide the total profile zip due to some security reason you can ask individual that we can provide. We have see that below path perticular host /usr/local/nagios/share/perfdata/host/xxxx/


The cpu.rrd is file not updated it is last update jan 10.
but the cpu.xml is updated.

Can you send me a screenshot or the file that contains how this cpu check is defined?

I want to see what the check_command is.

Also, could you run these commands and show us the output also?

Code: Select all

tail -50 /usr/local/nagios/var/perfdata.log

Code: Select all

tail -50 /usr/local/nagios/var/npcd.log

Hi team,

Please find the attachments. The below is the check command

$USER1$/check_ncpa.py -H $HOSTADDRESS$ $ARG1$

[kyang]

Could you PM me yournagios.cfg file.

Code: Select all

/usr/local/nagios/etc/nagios.cfg

You will need to increase the timeout for perfdata processing, edit the process_perfdata.cfg:

Code: Select all

/usr/local/nagios/etc/pnp/process_perfdata.cfg

Change:

Code: Select all

TIMEOUT = 5

To:

Code: Select all

TIMEOUT = 50

Restart npcd:

Code: Select all

service npcd restart

Wait about 15-20 mins and let me know how CPU performance graphs are after changing the TIMEOUT value.

Hi team,

Thanks for the reply. We are getting the issue only few hosts not all the hosts.
what does it mean PM?.
If change the time out values setting is there any effect to other monitoring services?
What is the impact if we restart the npcd. service?
What will happen if we change timeout = 50 ?

Hi, @Gonela.
We usually use PM for a personal message, short. Say, If we ask you for some log file and you don't want to upload it to a public forum for any security reason you could send it to us in a personal message.

If change the time out values setting is there any effect to other monitoring services?
What is the impact if we restart the npcd. service?

This means if you have a large system and NPCD daemon is dealing with a lot of performance data, you're increasing the maximum time it can work on a given process.
If you don't have enough hardware resources NPCD can no longer keep up rendering all the perf data on time, it times out after 5 seconds and cancels processes. That results in some or all performance data never being rendered.
Is the CPU graph completely empty? Do other services have graphs? Can you check on that for us?
