Nagios Support Forum

working now

had to delete user and group and re-run install

how about my question earlier about the subscription. what about customers who doesnt have RHEL subscription. they wont be able to add the optional channel.

That's a question you would have to ask Redhat, we do not control the need for the server to be subscribed to Redhats system.
If you do not want to worry about subscribing the server, use Centos7 instead.

Thanks you can close this ticket

So I finish the installation, everything well except I not getting any performance graphs. I checked the basics things and everything seems to be fine including NPCD

the only thing I noticed is the perf log file under /usr/local/nagios/var/ is empty.

If I go to a particular host->advance I can see perfomance data there

Verify that the perfdataproc command is running by the cron daemon by running If it is not running, restart cron by running If after 15 minutes, it still is not running, can you PM me or post your System Profile?
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 email it or post it here.
Also, run the following commands as root and post them here.

What is the load on the system? I would recommend checking if you have way too many perfdata files piled up in /usr/local/nagios/var/spool/perfdata or /usr/local/nagios/var/spool/xidpe/ directories, and increasing the logs verbosity by following our "Nagios XI - Performance Graph Problems" DB article here:

https://support.nagios.com/kb/article/n ... blems.html

If you are not able to identify the issue, please post both, the perfdata.log and npcd.log.

You are not using RAM disk, are you?

the load is almost 0

the perfdata.log is empty.

on the npcd.log dont see any errors

I prev stated that on the perf log file under /usr/local/nagios/var/ is empty. but the perflog under /usr/local/nagiosxi/var I see the following warnings


DONE. Processed 0 files.
PHP Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier.

I am found the following error in the perfdata.log file that is probably causing the issue. To fix this, disable the environment macros setting in the nagios.cfg file by changing the following line from to Save the file and restart nagios by running the following as root. Also, the system looks like it is using the ram disk but some settings are missing.
Take a look at this document to verify that all of the files have the correct settings.
https://assets.nagios.com/downloads/nag ... giosXI.pdf
The simplest thing to fix this is to run the Automatic RAM Disk Installation script.


The time error that you are seeing are caused from the time zone settings in the /etc/php.ini file that are missing. Go through this document and verify that all of the time settings are correct.
