My 1. problem:

Dude (on w2003) is sending Downs and ups were no event is ( pinging from the same machine at the same time) from the command line shows no packet loss.

Can I activate a debug log to show what is going on? I set up the ping-probe to try 3 pings with 1000 ms retry-time. Must the timeout of the probe set to 3 or 5 sec or will the first fired successfull ping return an result?

My 2. problem:
Notfications are scheduled no to be active between 23:00 and 6:00
If a device is going down in this time I will not receive an notification after 06:00. Will the repeat interval solve this issue?
