[Observium] Alert Checker Question

I have an alert checker called, "device down" and it tests for "device_status = 0". Occasionally, this alert will fire, but the underlying OS still has network connectivity to these device (ICMP). What this tells me, is that the underlying SNMP daemon on the server may be malfunctioning, because if OBS can't make and SNMP poll to a device, it makes sense to me that it would think the device_status = 0 for that device.

So given that this doesn't seem to be an OBS issue, is it something others have encountered and found away around? I'm Ubuntu 18.04 here... just wondering if I need to throttle the poller or if there are other known way the community has addressed this?

Thanks,

Ryan
