Hello Everyone,
After adding some host my Nagios crashed and delete the history and started again, so all the check were as status "pending".
I am using Nagios core version 3.4.1 and i am monitoring around 2.100 host and 20.000 checks.
The OS i am using is Linux Nagios-Master 3.2.0-4-686-pae #1 SMP Debian 3.2.68-1+deb7u3 i686 GNU/Linux.
I have several Nagios Sub servers that are sending the data to the Nagios Master via NSCA.
I couldn't find any error on my Nagios Master that could tell me whats happened there... i just added 20 hosts more and seems that Nagios Master couldn't handle it.. however there is no limitation for monitoring host with Nagios...
Did anyone have a similar issue?
Thank you in advance.

There is no "limitation" within Nagios, what it is going to boil down to is hardware, what are your server specs like?nerdgz wrote:Hello Everyone,

Hi,
It is a virtual server with 4 CPU's and 4 GB memory. I think with this hardware should be enough. This is the Master and only receive the data from the Nagios sub servers..

Re: Nagios reloading all configuration from scratch
Is updating to 4.0.8 something that is realistic? There have been a lot of performance increases since then. My other piece of advice would be to bump the RAM up some to see if that fixes anything, but updating core is my first suggestion. Make sure you take a snapshot first, of course.nerdgz wrote:Hi,

Re: Nagios reloading all configuration from scratch
Hello Everyone,
I could found out that it was I/O performance problems... since last time (a month ago) there was no problem with NAgios....
I could assume was that I/O thing...
I didn't change anything on the OS so, anyway planning to upgrade Nagios and server too....
Thanks for your time.
Issue can be closed
