Some Performance graphs not graphing

[pbroste]

Hello @hbouma

Thanks for following up, the system date, time, and timezone are sync'ed up. Let's then take a closer look at your 'rrdcached' output that looked wonky.

Code: Select all

systemctl -l status rrdcached --no-pager

Code: Select all

less /etc/systemd/system/multi-user.target.wants/rrdcached.service

Please forward the results,
Perry

Hello @hbouma

Thanks for sending the info over, want to take a look at the search results that you sent over.

find / -name rrdcached.service
/run/systemd/generator.late/rrdcached.service
/run/systemd/generator.late/runlevel5.target.wants/rrdcached.service
/run/systemd/generator.late/runlevel4.target.wants/rrdcached.service

/sys/fs/cgroup/devices/system.slice/rrdcached.service
/sys/fs/cgroup/systemd/system.slice/rrdcached.service

Let's take a look at the rrdcached.service files:

Code: Select all

find / -iname rrdcached.service -print -exec cat {} \; -exec echo \;find / -iname rrdcached.service -print -exec cat {} \; -exec echo \; >/tmp/rrdcachedresults.txt

Let's also get an updated System Profile as well (on both support forum issues):

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 @hbouma

Thanks for following up, we see a list of these listed and want to have you clear these out so they can rebuild.

rrd_update_r (/usr/local/nagios/share/perfdata/yourhostnamehere/Paging_File_Usage.rrd) failed with status -1.

Code: Select all

cd /usr/local/nagios/share/perfdata/<config name>

then find the RRDs and XML for these specific hosts and/or services and remove them.

Code: Select all

rm -rf <service_name.rrd>
rm -rf <service_name.xml>

The new RRD and XML files should get recreated in 10-20 min, and the graphs should start showing up

Code: Select all

watch -n 1 ls -l /usr/local/nagios/share/perfdata/yourhostnamehere/....

Thanks,
Perry

I see these messages in the messages.txt file from the Profile. How would I find these messages without running a new Profile?

I have gone through and deleted the rrdcached perfdata. I want to keep an eye on those messages to see if it clears up.

Hello @hbouma

You can watch messages from:

Code: Select all

tail -F /var/log/messages

or
tail -F /var/log/syslog
depending on distro.

Thanks,
Perry

[hbouma]

Thank you. I am no longer seeing these errors in the /var/log/messages on my RHEL system. The Graphs are now showing data as well.

Thank you for your assistance. Feel free to close this topic.

[pbroste]

Excellent, thanks for the update @hbouma, I will go ahead and lock this.

Thanks,
Perry
