What does the "downtime" channel on the cisco asa vpn sensor represent? What generates an error condition? In short ... what are ways to trigger a "down" condition on a vpn connection keeping in mind we have some connections that can go to sleep because of inactivity?

Thanks so very much

Hello,

the downtime channel is a part of each sensor (type). I'm afraid for the sensor it's a down/error if the VPN is not up / online. This of course could be the case if the connection is on "standby", unfortunately, there is no difference there on the OIDs, which the sensor reads, if it's a proper down or not. So we can only let the sensor alarm in all cases.

best regards.

Is there a workaround so we can distinguish between tunnel waiting for traffic and tunnel down ?

I'm very much afraid the Cisco ASA VPN Sensor in PRTG does not check for a OID differing between waiting for traffic and tunnel down. It's likely though, that there is an OID describing this very state. Please check with Cisco directly.
