The logs which are written to by the JCC are automatically rotated as required. The log settings are configurable in the Snaplex properties.

jcc_output.log is the stdout of the JCC process, not much output goes to the stdout usually and it is not automatically rotated. To enable log rotation for the stdout, ensure logrotate is configured on the machine and then create the file /etc/logrotate.d/jcc with the contents

/opt/snaplogic/run/log/jcc_output.log /opt/snaplogic/run/log/monitor.log {
    copytruncate
    compress
    size 100M
    rotate 10
    notifempty
}

To verify the logrotate configuration, run

sudo logrotate -vf /etc/logrotate.d/jcc

If the existing log is large, the first rotation can be slow because of the file copy required. To manually truncate the log file before enabling logrotate, do

sudo truncate -s 0 /opt/snaplogic/run/log/jcc_output.log

Hi Akidave,

where does the file gets archived after rotation?

Regular logs are backed up into the $SL_ROOT/run/log/backup folder https://docs-snaplogic.atlassian.net/wiki/spaces/SD/pages/1439068/Configuration+Options#Configuratio....

The stdout being rotated using logrotate configuration specified above will get backed up to files like /opt/snaplogic/run/log/jcc_output.log.1.gz, /opt/snaplogic/run/log/jcc_output.log.2.gz etc
