The alarm cache deployment is located on both app handlers of EXT servers currently in the usual location of /var/tomcat/alarmcache. Shutdown and startup is also as with every other application, the scripts are located at /var/tomcat/alarmcache/bin, these are run as non-sudo.
The normal log files are located in the usual location of ~/logs/grails/AlarmCache.log These are rolled over everyday and zipped up.
The catalina logs are located at /var/tomcat/alarmCache/logs/catalina.out
Both logs should be tailed on shutdown and startup to check for exceptions.
