Why does the Events tab not capture the events of the "Log Event Sources"

Issue

• Log events not appearing for configured event source
• Log tracking function is only able to track certain format of output file
• Log messages containing date/time format similar to the following are not captured

Feb 14, 2012 2:57:38 PM com.class.in.api.performance.LogThread run INFO: OFF - ../logs/HighLevelApiInterfaceLogging.log

• Log message formats different then default log4j format are not captured
• How should I specify the date format on jboss ON to load the lines of my log file in the event section? The date on my log file appears as follows:

2013-08-28 01:06:54,441

• All is correct but the file is still not read and the error in the agent.log is:

2016-02-26 12:34:56,009 WARN  [ResourceContainer.invoker.daemon-887] (core.pluginapi.event.log.LogFileEventResourceComponentHelper)- LOGFILE: Logfile at location /usr/data/log/test.log   does not exist or is not readable. The poller will be started but no events will be polled until the file is created.
