This is the alert checker I use to monitor and alert on ASA redundancy. It may not be what you are looking for as it does not alert on a failover event itself- the alert triggers when the cluster is no longer redundant and is cleared when both are up and in a normal HA state. I find this acceptable in my environment since it is more likely one is hard down (hardware failure, power outage, etc) rather than down due to a soft outage (software crash or interface link down). Basically I don't care if they failed over, I care if they *can't* fail over! If you want to alert on the HA event, a syslog alert would be an easy way to go. The ASA definitely throws a log you can match on.

Hi Adam,
Thanks for the syslog suggestion - I'll try that.

Do they generate useful syslog messages?

After diagnostic assistance from Adam it's sad to report that the Cisco ASA platform does not expose IP SLA details.
Any assistance or ideas for ASA HA failover alerting would be gratefully received - here what I have so far:

Many thanks

IPA SLA status is correctly reported from our core VSS switch but does not appear from ASA devices. Does anyone else see IP SLA reported from Cisco ASA firewalls? (Tried 9.7 and 9.8(2) software versions).
On the subject of Cisco ASA, does anyone have HA failover correctly alerting? I've tried to implement an alert but not quite mastered the technique.
