Hello Support,

We have several services that have stopped graphing the performance data. The performance data is still coming in, and other services are not having any issues.

In both the Nagios XI and the core interface it shows the performance data is coming in.

Can you advise on how to get the graphing to start again?

Hello @EchoUser

Thanks for reaching out, want to take a look at the System Profile so we can see what is going on.

To send us your system profile.

Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and send via Private Message

Thanks,
Perry

Hello @EchoUser

Thanks for sending over the System Profile, we see events logged in the 'npcd.logs' , because you're getting things like:

NPCD: WARN: MAX load reached: load 12.800000

Let's start with increasing the following values in these files:

/usr/local/nagios/etc/pnp/process_perfdata.cfg:
TIMEOUT = 15

/usr/local/nagios/etc/pnp/npcd.cfg:
sleep_time = 10

Try a timeout of greater than 30 and a sleep time of (greater than) 15 and see if that improves things.

Then do:
systemctl restart npcd

Thanks,
Perry

I have made the changes you suggested. I will review again tomorrow to see if items are graphing again.

Thanks.

The change doesn't seem to have made the graphing start working again.

Hello @EchoUser

Thanks for following up, let's start by looking at the perfdata for 'DESKTOP-BELIKOV'; interested in current timestamps, and populated xml/rdd host and services perfdata.

Code: Select all

ls -lahrt /usr/local/nagios/share/perfdata/DESKTOP-BELIKOV/

If you are not concerned with historical perfdata let's go ahead and clear the .xml and .rdd:

Code: Select all

cd /usr/local/nagios/share/perfdata/DESKTOP-BELIKOV/
rm -rf <service_name.rrd>
rm -rf <service_name.xml>

Restart ncpd service:

Code: Select all

systemctl restart npcd.service

make sure it started:

Code: Select all

systemctl status npcd.service

Increase the perfdata logging:

Code: Select all

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

Change:
log_level = 0
To:
log_level = -1

Nagios XI web console > Service Status, click on a "problem" service, go to the Advanced tab and show us a screenshot of the page. see example:

yourhostserviceadvanced.png

Then post the following files on the forum:

- /usr/local/nagios/etc/pnp/npcd.cfg
- /usr/local/nagios/etc/pnp/process_perfdata.cfg
- /usr/local/nagios/var/npcd.log
- /usr/local/nagios/var/perfdata.log

Onliner:

Code: Select all

cat /usr/local/nagios/etc/pnp/npcd.cfg > /tmp/results.txt && cat /usr/local/nagios/etc/pnp/process_perfdata.cfg >> /tmp/results.txt && cat /usr/local/nagios/var/npcd.log >> /tmp/results.txt && cat /usr/local/nagios/var/perfdata.log >> /tmp/results.txt && uptime >> /tmp/results.txt

Please send over the /tmp/results.txt

Thanks,
Perry

It looks like it hasn't updated the .rrd file since the date that the graph stopped. We were prefer to keep the history if possible, as there may be other services that are having the same issue.

Hello @EchoUser

Thanks for sending over the results, want to have you move the data in your '/usr/local/nagios/share/perfdata/DESKTOP-BELIKOV/' to a temp directory and watch it repopulate:

Code: Select all

mkdir -p /tmp/usr/local/nagios/share/perfdata/DESKTOP-BELIKOV && mv /usr/local/nagios/share/perfdata/DESKTOP-BELIKOV/* /tmp/usr/local/nagios/share/perfdata/DESKTOP-BELIKOV/

Then watch the directory:

Code: Select all

watch -n 3 ls /usr/local/nagios/share/perfdata/DESKTOP-BELIKOV/*

Wait for 30 minutes or so, then check perfdata graph.

The results that were sent over are missing logging and want to have you increase the logging.

After moving the content, the graph has started working, but the historical data is now no longer present (from before it stopped working). Is there a way to re-import that data back?
