I've been tasked to get an automated alert when our installed certificates are due to expire on the FortiGates. We are running 6.0.3, and I have not been able to find a good way to get an alert "X Days" before the cert expires.
We have internally generated certificates so sadly I won't be able to go down the request for an updated CA certificate route - but it's an interesting feature.
We do have fortianalyser so I'll check out to see if we have those errors in there (or when it gets closer to the time if they are generated) and do as you said. This will only be an issue if the FGs don't generate an alert for me to pull out...
