Hello, we recently had our cert for our VPN expire without notification via alert message. I've done some research in the FMC but can't find anything that monitors certificate expiration dates. A google search points toward REST API's of course but that's going to take me some time to learn. Not a skill to be ignored but lots of stuff on the plate.
Also, on a side note any of you who have Catalyst Center have you ever experienced a job being run that got stuck in "in progress" but never completes?

Good question. It looks like you need syslog server which can react to specific syslog messages and notify you via email or something. The messages are:
%ASA-1-717054: The type certificate in the trustpoint tp name is due to expire in number days. Expiration date and time Subject Name
subject name Issuer Name issuer name Serial Number serial number
%ASA-1-717055: The type certificate in the trustpoint tp name has expired. Expiration date and time Subject Name subject name Issuer
Name issuer name Serial Number serial number
They are produced by default:
crypt ca alerts expiration begin 60 repeat 7
To the best of my knowledge, FMC currently can only receive VPN syslogs from a pre-defined list ("Enable Logging to Secure Firewall Management Center" option under Devices > Platform Settings > Syslog), which results in:
logging list FMC_VPN_EVENT_LIST level errors class vpn
logging fmc MANAGER_VPN_EVENT_LIST
Messages 717054, 717055 belong to class "ca" and hence not sent to FMC, if I'm not mistaken. Also, it looks like we don't have Telegraph Health Module for managed devices which can react to certain syslogs (e.g. those with high severity level) generated from Lina and notify corresponding health module on the FMC so that it can generate health alert.
Sadly enough, we don't have full visibility to what happens on managed devices when FMC alone is used for management.

I found that FMC is able to warn you about expiring certificates on RA VPN dashboard (Overview > Dashboards > Remote Access VPN).
