Subject Re: chukwa agent stopped collecting log
Date Fri, 26 Aug 2011 16:33:24 GMT
Hi Ivy,

1. configure CHUKWA_PID_DIR to some where outside of /tmp directory to ensure the pid file
doesn't get removed by the OS.  
2. Chukwa has a predefined limit for chukwaAgent.fileTailingAdaptor.maxReadSize to be 128kb.
 It looks like you have entry longer than 128kb.  You can increase the number to 1024000 in
chukwa-agent-conf.xml file, and see if this helps. 

regards,
Eric
