Hi all,

I have a problem after migrating Nagios XI from a RedHat 32bit server to a CentOS 64bit (vmware image) server. I'm not able to get the performance data to show in Nagios XI. So when i go to a service and want to see the CPU load i only see "No data to display"

In /var/nagiosramdisk the are a host-perdata and service-perfdata with lots of data in it. But it just doesnt seem to get processed.

In the perfdata.log i see:

Does anybody know what i'm doing wrong?

How did you do the migration from 32bit to the 64bit CentOS?

Additionally, can you PM over a profile for us to look at? You can download it by navigating to Admin -> System Profile -> Download Profile

Posted: **Wed Jun 01, 2016 10:37 am**

i just upgraded the 32bit nagios to the latest version so it was the same as it is on the 64bit. After that i dit an nagios_xi_restore.sh on the 64bit server. I forgot to migrate the rrd files to 64bit but i just finished the instruction on https://support.nagios.com/kb/article.php?id=166 and the historic data is now available. i'm not quite sure if new data will be added now. i gues not. i cant send a pm because i am a noob on this forum. can i post a link for you to download?

Many tnx in advance! it has been a bit of a stressfull day

Posted: **Wed Jun 01, 2016 12:55 pm**

New data should be added, nice to see you got it working!

I believe after 2 posts you can send PM's, so you should be able to now. Please post back once you've sent it over.

Okay thx. I wont be able to check until tomorrow so, fingers crossed! I did send you the profile.zip file in pm. Maybe you could check for any human errors. The one thing i think might be a problem is that on the 32bit system nagios xi was installed by hand, so no vmware image. when starting nagios for the first time on the new system i got an error about a /var/nagiosramdisk folder not existing. i just created it and set the permissions. after that i did start. maybe there are some more directorys on 'non standard' locations, but i dont know.

There is a bit more then just creating the folder, take a look at this document for the ram disk and creating it -
https://assets.nagios.com/downloads/nag ... giosXI.pdf

Profile received - things look good at a quick glance, however it does look like your load is spiking which can affect performance data.

[05-31-2016 15:38:57] NPCD: WARN: MAX load reached: load 18.750000/10.000000 at i=1

Also seeing this - possibly also related to the disk IO? Did anything change in regards to the disk that hosts Nagios?

Okee, tnx. How could i change the configuration so i just uses the default file location? The ramdisk is for better performance i gues but this was only nessacery for the old server i gues. Now its on a 64bit server with 2 cores and 8GB memory. Is it easy to change to the default locaction and is there a link you can provide with the steps to follow. I'm more a Nagios admin and this is my first Nagios XI customer so im a little lost in the configs ..

Posted: **Thu Jun 02, 2016 3:42 am**

I think i found a solution. Because of the backup / restore to a different server the nagios.cfg on the new server has been altered by the old config. So the nagios.cfg on the new server had the complete old config. Now i just installed a new nagios server (default) and copied the nagios.cfg to my new restored server. I think this will set all settings back to de default locations and it seems to be working. Is there something anybody could think of that would go wrong is i do this of does it sound like a good solution?

Posted: **Thu Jun 02, 2016 7:16 am**

well that wasnt the solution eighter. i'm pretty lost right now. All is working fine but the performance graphs. Monitoring and notifying is al working. statistics are showing in the service detail section of nagios XI i also have the historical graphics data when i go to performance graph tab. but the new performance data is not added to the graphs. I dont know what is going wrong. Logging is not showing any errors (for what i can find)

The only thing i see is in /usr/local/nagios/var/perfdata.log

Code: Select all

Using Config File /usr/local/nagios/etc/pnp/process_perfdata.cfg
process_perfdata.pl-0.6.11 starting in SYNC Mode
Cant find Nagios Environment. Exiting ....

But this is al from yesterday before i converted the 32bit rrd data to the new server. Last update time is 2016-06-01 15:26:45 and no new enty's.

Any help would be much appriciated.

i need to say sorry to rkennedy! You were right about the ramdisk configuration. i didnt read the whole document because im a technician (nerd) and think i know better

The script didnt work, but below the script was the manual configuration instruction. After checking the whole document and al the config files and folders it was obvious about 80% of the config was incorrect. i corrected it al and now the performance graphs are building again.

Tnx for the support!!
