I'm using PRTG to monitor a large selections of servers, mainly for backups (Symantec System Recovery primarily).
I'm testing WMI and SNMP sensors at the moment and can successfully receive the backup job status messages from each of these. However I don't want to rely on jobs reporting failures.
With the IMAP sensor you can set the status to down if it doesn't see a success message. Due to limitations to the number of concurrent connections to the mail server, switching to this doesn't seem possible.
Can "Set status to down if no success in X hours" be set on any other sensors?
