Hello Nagios Support,

We are very close to purchase a couple of Nagios licenses for our projects and we had decided to deploy your nagios VM machine (version 2014r2.0) in Our VM ESXI host 5.5.0, I had installed VMtools on the VM, Upgraded RAM to 4GB and configured 8 host for ping services and 2 SNMP routers for network traffic, and the load spikes occurrs every 5~7 hours, these up to 70 and over.
-All the host has been added using the monitoring wizards.

After Reading all these posts I had tried everything here,as a final hope I have upgraded my nagios XI to Verson 2014R2.3, at the begining it seems to be working but then the spikes appeared as shows,

I had just changed in this VM ;
According the document http://assets.nagios.com/downloads/nagi ... ios-XI.pdf
The reaper timers in: usr/local/nagios/etc/nagios.cfg
check_result_reaper_frequency=3
max_check_result_reaper_time=10
and according to http://nagios.sourceforge.net/docs/nagi ... ule_checks
use_aggressive_host_checking=0
passive_host_checks_are_soft=1

and this is what i Got:

Top Nagios JAN-08.1.PNG

I have The CentOS 6.6(final)
Kernel 2.6.32-504.1.3.e16.x86_64 on an x86_64
Rightnow, I dont have any other VM running in the ESXI

My question is, How can I avoid this ?
why this is happening if I had dowloaded your VM image and I haven't change anything else on the VM?

I would appreciate your response
Regards,

Do you see any errors in the mysqld.log? Crashed tables can cause this behavior.

Code: Select all

tail -50 /var/log/mysqld.log

just in case I had ran the repair scripts without errors
/usr/local/nagiosxi/scripts/repairmysql.sh nagios
/usr/local/nagiosxi/scripts/repairmysql.sh nagiosql

By the way, from yesterday to now, I have had this behaviour, a really big peak (150) at 5pm and then smaller peaks (below 50) :

hope this helps you to find a root cause for this.

Hello Guys,

The Nagios is totally stalted. no web interface, no response via console. only these messages.
According to my ESXI, the VM is consuming all te RAM(4GB) and processor (1595Mhz) available.

Any Idea?
Please,

After doing some research this is a common problem in CentOS 6.6 and usually is fixed by a firmware update. Can you try updating your hardwares firmware?

Hi,

What do you mean with hardware firmware upgrade? If we are using a VM ( the virtual machine available to download from your website http://library.nagios.com/library/produ ... loads/main 64bits) i think this VM should have the latest upgrades installed, we have already installed VM tools (that are supossed to be the Hardware drivers for the VM) . there wont be any hardware problems right?

please clarify this

At the moment the machine is totally unresposive, we are going to upgrade all the packages for this centos Version as soon we can get control of the VM.

As told you before we are using ESXI 5.5.0 in a physical Fujitsu Server model rx300 S3

Regards,

I just researched the errors that you posted and the trend was people running versions of CentOS on a machine with outdated firmware got the exact same error. Not saying this is the source of the problem since you are running on a VM, but there is something with the VM that may be corrupted giving you this error.
