Nagios performance data not working

MOD NOTE: Split from https://support.nagios.com/forum/viewto ... 16&t=44950

I ran the install_ramdisk.sh. That seemed to have fixed the performance grapher crashing issue but now I donot see any RRD file being created. Can you please help.

Thanks
Krishna

Please take a look at https://support.nagios.com/kb/article.php?id=9, but be sure to adjust your file paths to the ramdisk file paths.

Additionally, can you PM me your Profile? You can download it by going to Admin > System Config > System Profile and click the ***Download Profile*** button towards the top. If for whatever reason you *cannot* download the profile, please put the output of View System Info (5.3.4+, Show Profile if older) in the thread (that will at least get us some info). This will give us access to many of the logs we would otherwise ask for individually. If security is a concern, you can unzip the profile take out what you like, and then zip it up again. We may end up needing something you remove, but we can ask for that specifically.

You can also generate a profile manually using the script at /usr/local/nagiosxi/html/includes/components/profile/getprofile.sh

That should generate a profile in /usr/local/nagiosxi/var/components/ which you can get off the server with an application such as FileZilla.

After you PM the profile, please update this thread. Updating this thread is the only way for it to show back up on our dashboard.

If you get an error that PROFILE BUILD FAILED, please see https://support.nagios.com/kb/article.p ... ategory=44

Hi @ vuduops

Nagios spools small files that are moved around and processed. Sometimes these spooled files get filled up.

You will need to count the amount of these spooled files. The standard amount should be number <=20,000 which healthy.

If any number comes up above 20,000,you will need to delete some because some processes will get caught up in a loop.

Please follow the steps below to resolve this issue.

1.Count the amount of these spooled files by running the command below:

The output for these commands will be a number

Code: Select all

ls /usr/local/nagios/var/spool/perfdata/ | wc -l

Code: Select all

ls /usr/local/nagios/var/spool/xidpe/ | wc -l

Remember,if you get a large number above 20,000 it means problems.

2.If it is a large number above 20,000 those files need to be deleted so please run the command below to delete them.

Code: Select all

find /usr/local/nagios/var/spool/perfdata/ -type f -delete

3.PLEASE WAIT 30 MINUTES TO SEE IF THE PERFORMANCE GRAPHS ARE WORKING AGAIN.

Please try that and let me know if it worked or if you have any questions.

Otherwise if we will have to change verbosity for performance data logging to a higher lever in performance.cfg and npcd.cfg files.

Note: NPCD deamon is responsible for processing performance data. That is why i mentioned its configuration file(npcd.cfg ) above in regards to increasing logging verbosity.

However,don't worry about that for now,first try what i mentioned in the first three steps above.

This is what I see. Still no rrd file being generated

Code: Select all

[[email protected] tmp]#     ls /usr/local/nagios/var/spool/perfdata/ | wc -l
1
[[email protected] tmp]#     ls /usr/local/nagios/var/spool/xidpe/ | wc -l

@vuduops, Can you check the contents of this folder:

Code: Select all

/var/nagiosramdisk/spool/perfdata/

Also based on the log files you need to increase resource load threshold in order for npcd to run correctly:

Code: Select all

 Open the npcd config file:
/usr/local/nagios/etc/pnp/npcd.cfg
And change this line:
load_threshold = 10.0
to this:
load_threshold = 20.0
Save and exit

When that is done please restart npcd daemon:
service npcd restart

I took a look at your profile and it looks like the install_ramdisk.sh script did not change all of the files so that is the reason the RRD files are not getting created / updated.
You can try and run the script again and see if the rest of the files get updated or you can manually update the files be doing the manual process in this PDF file.
