Yes, syslog message# 104001, 104002

There are a few more within the 104xxx range in regards to failover that you might be interested:

Hope that helps.

Try this and it works for me when failover mates change and sends alert immediately... This sends both syslogs messages 7 and mail. For traps syslog, o enable debug fover commands on both devices if you need to troubleshoot further of the failover changes in details (pcap).. Hope this helps...
