Capture SSL handshae failure via iRule

Hello all.
I would like to ask for help when building iRule for SSL. We are in migration of our service from RSA to ECDSA cipher suite (because of security findings) and I need to log following via iRule:
-- client IP and destination URL
-- and choosed cipher when successful handshake
-- or provide an error for handshake failure in case there is no matching cipher

So far, I have following simple iRule:

when FLOW_INIT {
    log local0. "S: [IP::client_addr] starting session ..."
}

when HTTP_REQUEST { 
    log local0. "S: [IP::client_addr] --> [HTTP::host], cipher [SSL::cipher name]" 
}

Via it, I'm able to catch start of session and the first 2 points.
Example:

May 24 13:53:30 lb-test01 info tmm1[19834]: Rule /DMZPCI/IRULE_SSL_cipher_show <FLOW_INIT>: S: 192.168.22.51%2 starting session
May 24 13:53:30 lb-test01 info tmm1[19834]: Rule /DMZPCI/IRULE_SSL_cipher_show <HTTP_REQUEST>: S: 192.168.22.51%2 --> shop.test-domain.com, cipher ECDHE-RSA-AES128-GCM-SHA256

However, when the failure occurs, I can get only start of session and if I need to check for SSL result, I need to grep the source IP:

# tail -f /var/log/ltm | grep 192.168.22.51
May 24 13:54:33 lb-test01 info tmm1[19834]: Rule /DMZPCI/IRULE_SSL_cipher_show <FLOW_INIT>: S: 192.168.22.51%2 starting session
May 24 13:54:33 lb-test01 warning tmm1[19834]: 01260009:4: 192.168.22.51%2:62236 -> 192.168.22.103%2:443: Connection error: ssl_select_suite:10065: alert(40) no shared ciphers
May 24 13:54:33 lb-test01 warning tmm1[19834]: 01260026:4: No shared ciphers between SSL peers 192.168.22.51.62236:192.168.22.103.443.

My question -- in iRule, is it possible to catch also the failure and log it, so I don't need to look for it manually (it is public service, meaning there are hundreds of connections every minute).

Thank you very much.

Best Regards
