Hi,
We are sending syslog messages from device . I made changes in opennms to
parse syslog messages. I changed the below files :
i) Created a new event file and added that file in eventconf.xml
ii) Added the new event in drools-engine.xml and written rules in
eventMappingRules.drl
.
I restarted opennms . I got the below error in output.log ,
Caused by: java.lang.RuntimeException: Unable to initialize Drools engine

I think the error was due to the new rules added.
