Graph Explorer issue

Posted: Thu Jun 25, 2015 4:18 am

Hi,

I have all hosts inside the graph explorer. My issue is, for some hosts, there are some services that do not generate graps (e.g. memory usage). What could be the reason for it? Where can I check the configuration for Graph Explorer?

Thank you in advance.

Do you see the graphs when you go to: Service Detail-><your service>->Performance Graphs? What is the version of the Nagios XI that you are currently using?

Try to access the graph in the Graph Explorer, then run the following command and show us the output if code wraps:

Code: Select all

tail -50 /var/log/httpd/error_log

Unfortunately, I don't see it too when I go to: Service Detail-><your service>->Performance Graphs. Nagios XI version is 2014R1.3.

If you don't see a graph under the "Service Status Detail" ("Performance Graphs" tab), you are not going to see it under the "Graph Explorer", either.

Can you click on the "Advanced" tab under the "Service Status Detail" page and show us a screenshot of this page?

Also, run:

Code: Select all

ll -d /usr/local/nagios/share/perfdata/<host name>
ll /usr/local/nagios/share/perfdata/<host name>
and show us the output. Please, substitute "<host name>" with the actual hostname of the host to which the "problem" service is added.

I believe the issue is in the multiple semicolons (";;;;"). The performance data should look like something like this:

Code: Select all

'TOTAL'=valueKB;'USED'=valueKB;'FREE'=valueKB;'CACHES'=valueKB;
https://nagios-plugins.org/doc/guidelines.html#AEN200

What is the plugin that you are using? Can you provide us with a download link to it? We can test it in-house.

Also, show us the actual check run from the command line, along with the output of it.

If this is the case, it will show up in the logs.

Lets increase the logging verbosity and then take a deeper look into the logs. Follow the FAQ entry below to increase the log level of process_perfdata and npcd:

http://support.nagios.com/wiki/index.ph ... leshooting

Wait 15 - 20 minutes and then get a tail of the logs:

Code: Select all

tail -250 /usr/local/nagios/var/perfdata.log > /tmp/perfdata.txt
tail -250 /usr/local/nagios/var/npcd.log > /tmp/npcd.txt
Send us a copy of /tmp/perfdata.txt and /tmp/npcd.txt

Don't forget to turn down the log level as per the FAQ when you are done!

I got it from the link below:
http://sysadminsjourney.com/content/200 ... os-plugin/

root@RCS-PROD-WCAS-01:/usr/lib/nagios/plugins# ./check_mem.pl -f -C -w 5 -c 1
OK - 72.1% (11849624 kB) free.|TOTAL=16429872KB;;;; USED=4580248KB;15608378;16265573;; FREE=11849624KB;;;; CACHES=4744340KB;;;;

I modified the plugin but it still does not produce graphs.
