my server freaks out sometimes!
* Hi, I am using the pro version Observium 23.8.12912 (stable)https://www.observium.org/ I am having an issue where over the course of 2 hours (or so) all my devices go down and then up. It claims that it missed pings but there is no issue with any of the devices. This has happened to me 2 times in the past 3 months, both times starting at midnight. When I look in the event log, I am seeing some odd things on that date: [cid:image004.jpg@01D9D4D7.42656A20]
First, notice that there are a bunch of snmp timeouts which do not occur on any other day. Also, it seems that all the devices have changes...again this does not happen on any other night. After the first incident I increased the RAM on the server thinking that it was constrained, but the poller info does not look bad: [cid:image005.jpg@01D9D4D7.42656A20]
I would appreciate help in determining what to look at for the cause of this. Thanks

This is likely a firewall or similar intervening device being unhappy at UDP volume and rate limiting.
It's likely that your discovery run starts at midnight, so increases SNMP UDP traffic.
