Get specific rule by log code

[koby]

Hello All ,
Does anyone know how can I get the specific rule from the log message who look like this :
"notify <koby@mksoft.co.il> (rule: DefBlockSubject, AC81C21C94)"
I need to get the specific rule for : AC81C21C94 (example code from my message log)
How / where I can get this data from ?

Best Regards ,
