Nagios Support Forum

Hello again!

We've had some improvements in terms of performance after I executed those changes you asked. But most checks are done within 15 minutes (80%) and (20%) within 5 minutes. It's better than before but it is still a low percentage Meanwhile, I've noticed that, and it might have an effect on the performance, nagios is checking twice a service, having the same time period but different results.
Do you agree that it's odd?!
Best Regards

The server does have a lot of Check Latency which is not a good thing.
You may want to try some of these tips to optimize your server's performance. Take a look at this link.

You may also want to look in to upgrading to core 4.x.x as there are a log of performance enhancements done since 3.5.1.

Hello!

I will check the link you gave me.

About the upgrade, which version of ndoutils nagios 4.x.x is compatible with?
Thank you

Your welcome.
The latest released version of the ndoutils (2.0.0) works with the latest released version of Nagios Core 4.1.1.
