Hello all, I’ve been using Librenms for about 4 weeks now and have had a reoccurring issue… at random times, I’ll get warnings that all my devices are offline. However, they are not, I can connect to all of them (I have 52 devices on my network that I monitor).
They will remain “offline” for a random time (normally a couple hours), then come back online.
If I restart the Librenms server, they are back online once the server starts back up. If I reset the NIC card (turn it off and on again in the GUI), and manually run ./poller.php -h all, they begin coming back online as it polls. If I try this without resetting the NIC card, the poll fails.
This server was running on a dell R420 with 64gb memory / dual xeon … but had the issue there, so I installed on a HyperV VM in order to try and trouble shoot with known good hardware.
Any help would be appreciated… I thought my internet gateway (I use untangle) was blocking or limiting snmp (port 161) in some way, but I have that protocol bypassing any scanning it might be doing.
I’ve put the output to the validate below. Thanks in advance, Tim
