[nv-l] VPN staue threshold

[adam.paisley@elekta.com]

Hi list,
I'm a little stuck for an approach to
generate events for when a vpn interface goes down.

The mib table contains the vpn status
for a number of vpn tunnels.  These are reported as a 1 for up and
0 for down.  

Initially I thought I'd use a simple
data collection and threshold, but the trigger is > "a value"
and re-arm <= "a value" - this is the opposite to how the
device is working. 

I'm thinking that this is a fairly standard
thing to be able to solve - can anyone offer any pointers on how to do
this - I've checked the archive & it only seems to mention calculating
positive thresholds.  A thought I've got is that I can set the threshold
> 0 and re-arm <=0 which will cause it to trigger all the time, then
use a rule to get the mib value (will the trap include that?) and then
do something with it in the rule to decide if it should be sent onwards
to TEC.

Any thoughts appreciated.



Thanks
Adam
