Regards,
Engineers proceeded to update the latest version of Nagios (Nagios XI 2011R3.2 Copyright © 2008-2012 Nagios Enterprises, LLC.) And restarted the server 4 times, the platform still remains fully degraded.
We have the license to XI, as we could use this support? What are the limitations of this?
You could connect to our platform and validate our setup? Or what kind of support we can arrange with you to help us the most quickly as possible.
As I am always very attentive to your prompt response.

Re: next check
From reviewing the earlier screenshots you sent from the XI dashboard, it seems like your issue could be disk I/O. VM's don't perform as well on Disk I/O as a physical server will. Your CPU load seems healthy for the amount of CPU cores that you have. I think that the disk writes are not able to keep up with the check schedule. Can you post your /usr/local/nagios/etc/nagios.cfg file and then I would also review our documentation on using a RAM disk to try and free up some disk activity.

Engineers sent nagios.cfg configuration file. for the scheme (RAM Disk) we tried to configure but this presented problems because the configurábamos correctly but when rebooting the server did not recognize this new configuration, so we mitigate this level of virtualization where the vcenter to configure the data storege disk given unlimited resources.
And then the vendor who sold us the solution (http://www.fware.pro) argument that you could not stand this kind of solution.
As always we were very attentive.

Can you show from running top, filtered by CPU time what the top 5 processes are?
We do support the RAM disk solution. Even with unlimited disk usage allocated to the VM, the limitation is on the physical disk, and this VM is still having to share with others. We have made updates and improvements to the RAM disk documentation since originally writing it. I would consider it for your scenario.

Engineers to email address I can send the requested images? Also to send screen shots showing that the virtual machine to Nagios is in a single resource pool, this ensures the resources of memory, CPU and storage, network cards.
I am very aware of your confirmation email.

Re: next check
Got the screenshots. Change of theory. SNMP polling has a certain amount of wait time on the device's end of things, so it's possible that the lag time of the checks is slowly blocking the main nagios loop while it waits for the checks to return results. I do still think that Disk I\O issues are just as likely, but you could start with a simple experiment by increasing the check_interval for a large batch of your SNMP checks from 5mn to 7-10mn and see if that makes a difference in the latency.
