Thanks for everyone's reply. I'm going to enable the Nagios server again this weekend to see if I notice any bandwidth issues. I'm also going to run a few packet captures as well and share them as I get them this weekend.dwhitfield wrote:At the time, the info about it being a VPS was not posted. I was thinking maybe the entire network was having issues. I mostly agree with the above at this point, though I am still curious about how the PBX network is setup. Like, are all the phones on the same network?tacolover101 wrote: i think the size of your nagios server is irrelevant here.
It seems to me the real issue is why is the phone system not responding? The network may have high non-nagios related traffic at those times.
Are you monitoring bandwidth on the Nagios server? That could tell us if it's something coming from the server, whether ping or not.
The issue was never that the phone system was not responding, it was being monitored just fine. While being monitored is when the issues occur and the only way I knew this was happening was because a client called me.
Here is the network in a nutshell;
ISP -----------------------> WAN PfSense
LAN PfSense -------------> Cisco SG300 PoE
Cisco SG300 PoE ---------> (4) VoIP Phones, PBX System
Nagios is pinging the WAN interface on the PfSense
Nagios and the PfSense are not on the same network
I'm sure its just a setting in Nagios that I need to find. I think the packet captures will tell the real story on this one.
