Hi Ricardo,

It shouldn't give false positives unless you're device is going down or has bad connectivity.

A device is marked as down if it's unreachable by either PING or SNMP at the start of the poller run (the poller will stop here and nothing else will be checked).

If you have problems with devices failing to respond quickly enough you can try increasing snmp/ping timeouts and retries, but you'll probably have other problems elsewhere.

Hi,

I have a checker set up like this:

device_status = 0

This gives an alert when the device is down. Unfortunately it gives lots of false positives, so perhaps I do not understand good enough how this checker checks if the connection is down or not ?

What exactly does it check to see if the device is down?

Kind regards,

Ricardo Franco
