Nagios server performance optimization

[kgopiramesh]

Hi Experts,

Please find the below for our environment details

We are running with 1 CPU 4 cores and 2750 services ( All active checks) and the polling interval of 5 mins.

The load average is too high and I observed that notifications are getting delayed, The mails are getting queued up

please let me know if there is any way to tune the performance.

What is your load average, please show the output of:

Code: Select all

top | head -6

You could look at implimenting a ram disk, and or offloading the database. Mod gearman would also make a big difference, or possibly testing out the worker processes that are being shipped with Core 4 that is in the 2014 beta. You can install the beta on a test system to see how it performs.

I have a few queries on your suggestions, can we implement on worker processes on nagios 2.9 XI 2012

and when I searched for the mod gearman it is helpful for distributed monitoring that is we need another system which is not possible in our environment.

I would recommend reviewing the "Boosting Performance" section in the Administrator's Guide:

Hope this helps.
