Subject Re: Flume custom source stopping after some time when started through java program.
Date Mon, 14 Jul 2014 11:18:38 GMT
No i am using flume provided source exec , just to tail -F <logfile>

I start flume as below,

/bin/flume-ng agent -c /d0/flume/conf -f
/d0/flume/conf/flume-conf.properties -n a1
-Dflume.root.logger=DEBUG,LOGFILE &

I get logs in flume.log file.I could see flume agent running from ps.

I use file/memory channel..Agents data for sometime but stops after that ,
but it doesnt happen in certain interval as you mentioned 6 hrs , it
happens randomly.

I think channel might gets full.NOt sure how to verfiy the same.Any idea?

Please tell me how to enable logging to identify when source stops.
