How to automate checking certificate expiry

We are wondering if there is a way to automate checking when certificates are about to expire. We have several different certificates in TN for different partners in our system, and would like to be notified a couple of weeks before they expire so that we can schedule the replacement ahead of time. Has anyone done this before? We have version 6.1. Thx.

Looks quite useful . . . thanks a bunch!

We have done that before. Let me know if you still need help.
