Cisco monitor crypto engine?

Hi there,

I have a whole bunch of 2811s that I am sending almost 100% of our traffic through the onboard crypto engine.  I have some sites with more bandwidth than others and I need to monitor the crypto engine to determine if its overloaded/dropping packets.  I also have 7200s with SA-VAM2+ doing the same thing.

It would be great if this could be collected via snmp but the only way I have found is via the command "show crypto engine accelerator statistic"

show crypto engine accelerator statistic

So I really want to see this somewhere that I can create an alert on it and add it to my dashboard.  Unfortunatly I dont think there is any easy way to determine the "Load" on the crypto engine.  From my understanding though if its dropping packets its overloaded.

    Anyone?

    I need to monitor when packets are being dropped due to the crypto accelerator not being able to handle the traffic.  This stat is not exposed via SNMP so I am going to need to poll via a script or something then compare it to the previous query to determine if there have been any additional packets lost.  If so I have to trigger an alert.

    This is the output of the command I need to monitor. 
    show cry engine acc statistic | i dropped
            pkts dropped:      113701

    The Universal Device Poller will not work because this is not accessible via SNMP.

    Is there any other way to monitor this?

    Thanks.
