chukwa agent stopped collecting log

Hi Eric,

    I met with two problems.
   1. Chukwa agent suddenly stopped again. After checking the agent log , we
found these logs
           2011-08-26 00:42:16,589 ERROR Thread-1 PidFile - Delete pid file,
No such file or directory: /tmp/chukwa/pidDir/Agent.pid
           2011-08-26 00:42:16,598 ERROR Thread-1 PidFile - Delete pid file
failed, /tmp/chukwa/pidDir/Agent.pid
       Which circumstance would cause these logs?

    2. The chukwa agent was still on , but it stopped collecting log.

And after i restart the chukwa agent ,the log
        2011-08-26 11:10:49,807 WARN Thread-2 FileTailingAdaptor -
bufferRead == MAX_READ_SIZE AND bytesUsed == 0, dropping current buffer:
startOffset=26653892, MAX_READ_SIZE=131072, for /var/log/gamelog
appeared frequently . Once it appeared , i only can restart the chukwa
agent.

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
