Performance Graphing Issue with 5.2.7

[CarlWedu]

Just completed upgrade to 5.2.7 (thanks for the help!) and still having issues with some performance graphs. Ping graphs from network hosts work fine, but bandwidth graphs for interfaces do not.

Running through some of the pertinent FAQ steps and found this that looks problematic:

Code: Select all

Thank you!

Can you run the following 2 commands and post the output?

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
ls -l /var/lib/mrtg

In your post, those files have not been updated since 2014 and the above commands may show why.

[CarlWedu]

[root@nagiosxi ~]# LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
ERROR: could not find RRDs.pm. Use LibAdd: in mrtg.cfg to help mrtg find RRDs.pm


Other command attached as its too large to post.

Thanks!

Also potentially of note, there are far more graphs than needed. This whole Nagios setup is inherited and I am trying to get it corrected. Very much appreciate the help and patience along the way!!

[tmcdonald]

A few questions:

• Do you recall what XI version this was before the upgrade?
• How many is "far more graphs than needed"?
• What's your host/service count vs the number of graphs?

• How many is "far more graphs than needed"?
• What's your host/service count vs the number of graphs?

Almost certain it was 2014R1.5

Do not have a specific number but there are a majority of switches that would be better with a ~80% reduction in services. There are approximately 4700 services that are network-related. Safe estimate: we could do without 70% of those.

287 hosts; 5201 services; 4273 graph files (based on the count from the previously posted ls command; seems like there should be more than that though as I am not seeing some server graphs in there)

Try this:

Code: Select all

yum install rrdtool-perl

If it says it's already installed, post the output of this command:

Code: Select all

find / -name RRDs.pm

Thank you

Installed:
rrdtool-perl.x86_64 0:1.3.8-7.el6

Dependency Updated:
rrdtool.x86_64 0:1.3.8-7.el6 rrdtool-python.x86_64 0:1.3.8-7.el6


Next steps? Another note: prefer to remove historical data given its lack of utility once the graphing is functioning correctly.

Seeing data in graphs across network devices now. Thank you!

I plan to proceed with removing and re-adding network devices in order to clear out unnecessary historical data and reconfigure what is actually monitored (to reduce service counts and improve utility.) Please let me know if you have any additional suggestions in regards to those plans.

Thank you again!!

I am glad your issue has been resolved!

Before rerunning the switch wizard, you could remove the unnecessary files by following the steps, outlined in the document below:
