Re: SNMP - error: Alarm signal (Nagios time-out)

I'm leaning toward network issues, especially considering this is intermittent/not all services, and SNMP is UDP-based which, if there is no SNMP-level checking going on for received packets, might lead to the timeout you are seeing.
Let us know what you come up with for the ping times. A useful tool for stacking two graphs is under the Home -> Graph Explorer page, in the Multistacked Performance Graph tab.

It's what I would suppose too, but as soon I saw one error I took a printscreen and after a few hours I went into Nagios and checked it with the multistacked graphs, no packets lost on the virtual machine, ESXi host, switch and router (remote site, as Nagios sits on the AWS).
I even noticed that one of our servers within the AWS cloud (not sure if it's the same data center location, as this is an outsourced service) got the same timeout.
I will be checking this deeper, and let You know.
Should I think of updating to 5.3.0? I'm still on 5.2.9, as I saw that there were some problems pointed out in the forum.

I would hold off on upgrading to XI 5.3 at the moment until the developers get a chance to look into the notifications issue (not sending notifications) to see if we are still running into it.
