I just finished doing an upgrade to the latest version of NagiosXI and now my server is getting high load averages.
Also, we are running the Linux virtual appliance.

Here is what top looks like:

Has anyone been experiencing this issue?

What is the Nagios XI version that you upgraded from? What the load used to be prior to the upgrade? Are you using mod gearman or mklivestatus?

Looking at the code you posted it look like httpd is where most of the load is. Are there a large number of users accessing the UI?

I have attached another picture of what the load looked like this morning when I got into the office.

We only had like 3 people access the server.

We upgraded from Nagios XI 2012R2.4 or 2.0.

We are at 2014R2.0 now.

We are using the virtual appliance and it currently has 1 cpu and 10GB RAM assigned to it right now.

Wow, this top shows 995 processes, something is definitely wrong here, I know already I see WAY too many mrtg processes running...

Additionally, is this machine only running with 1GB of RAM? How many hosts/services are you running?

http://assets.nagios.com/downloads/nagi ... ements.pdf

Can you run the following and send the top.txt

Code: Select all

killall -9 mrtg
ps -ef > /tmp/top.txt

thanks

DUH!

I apologize, that was an oversight on my part. I didn't implement this appliance, just inherited it, and assumed the resources were enough. I have increased the RAM and CPU's, all seems to be running within normal ranges. I do have another issue, in that the performance data is not showing up on the graphs but I will open up a separate thread for that issue.

Thanks
