just noticed this morning our CAS system status is red, mainly due to AMD SSL Status is alerting that percentage of SSL errors since last night: 100. this is the first time we've seen this error, what caused this and what's the 1st step to troubleshoot. we're using DCRUM 12.2 and AMD 22.214.171.124
Do you have SSL keys installed on the AMD to be able to decrypt the traffic?
There is quite a bit of documentation around SSL but first steps are to check if SSL keys are installed and if they match the monitored traffic.
You can do this by using executing "rcmd show ssldecr keys" to view the status of any configured SSL keys.
from the attach ssldecr_show_status details,
Finished sessions not decrypted=7564 (100% of all finished sessions)
with no private key found=7550 (new sessions=7550 reused sessions=0)
most likely the server being monitored had the SSL cert/key updated or renewed, and now the AMD's key for it is out of date
