[Observium] An Event Log annoyance

Hello,

I'm currently running Observium 20.4.10353(rolling) in my test (home office) environment. I had to restart everything 2 days ago when I brought in a new desk and rearranged. I'm monitoring 4 devices: a server (running observium), a Cisco ASA 5505 firewall, a Cisco wireless access point, and an APC UPS with Web/SNMP Management card.

Everything is working fine since the restart, except that every 5 minutes I get a new entry in the Event log telling me about how my ASA rebooted; I'm attaching a screenshot. That's the only device that's showing up in the event log.

How can I convince observium that it doesn't need to keep telling me about it?

Thanks,   - Richard
