Nagios Performance is not stable

[justine]

Kindly help. Load average of our localhost is always high (25.84, 21.56, 18.23). Performance graph is not working either. Our NagiosXI version is 5.4.2. It is running in Vsphere. Linux CentOS 5 is it's OS. We are also using Ramdisk. Please advise what is causing this errors in our Nagios server. On my other post, Nagvis is also affected. It doesn't work anymore. I hope somebody could help me. Thanks in advance.

We will likely need more information.

How many hosts/services are on the system?
What is your average check frequency?
How many CPU's does this server have?
How much RAM is allocated to the system?
Are there other systems on the Vsphere server that could be using a lot of the disk availability?

It may also help us understand a lot if you could PM me a System Profile:
Admin > System Config > System Profile

Hi scottwilkerson,

We have 359 Hosts and 1582 Services.
Memory is 16GB.
It has 8 CPUs @ 2.20GHz.
Load average is 4.77, 5.19, 5.64
Usually our check interval is 5min, 1min and 5 attempts.
For diskspace, / is only 46% used of 250G and /var is 82% used of 76G. We also have /var/nagiosramdisk in 500M size. But right now its 92% used.
I will be sending our system profile to you.

Thanks.

Being you have a licensed system I am going to request you open a support ticket with our staff so they can get the profile. Please send an email to [email protected] including your profile you were not able to PM because of size.

Also, please include an answer to the following

Are there other systems on the Vsphere server that could be using a lot of the disk availability?

It would be especially helpful if the system profile was taken when the load was high like you explained in your OP.

This load is not typical for a server with the amount of hosts/services you have, and the profile will likely hold the key to what is causing the problem if it isn't being caused by other VM's on Vsphere
