[mrtg] Sensing down sites/interfaces?

[Arvon Griffiths]

Right now, when mrtg has an interface that fails to respond, an entry is written to /var/mail/username.   I REALLY don't want to have to continually scan and parse that file for entries nor do I really want to increase our snmp traffic by your suggestion Ashok (but clever fix anyway).

Is there no way to use mrtg's mechanism that generates the mail entries to trigger or pass that info to another process when an snmp request fails?

Thnx
