Syslog messages

[Dennis100]

I'm running Kiwi Syslog server and am using that to accumulate messages as well as notifying me during emergencies. One of the emergency message I'd like to set up is when a gateway goes down (dual WAN setup).

Is there a list of syslog messages Pfsense can generate showing their format? I'm currently interested in gateway failures but others will undoubtedly come up.
