Housekeeping

Log cleaning in DMK

dbi services provides a cleaning script named housekeeping.py that performs several types of operations on log files.

• Deletion of old files

• Truncation of files

• Compression of old files

• Archiving of files (truncation + compression)

The script should be run as housekeeping.py -c $MONGO_BASE/etc/housekeeping.conf. You can find a template for the housekeeping.conf file in $DMK_HOME/templates/etc/housekeeping.conf.

Default settings

You can set default settings for the main operations with the DEF keyword:

$MONGO_BASE/etc/housekeeping.conf

DEF::DELET::100:: # Delete files older than 100 days
DEF::TRUNC::1000:: # Keep the last 1000 lines
DEF::ARCHI::1000:: # Backup the file and keep the last 1000 lines
DEF::COMPR::100:: # Compress files only if older than 100 days

Custom settings

You can define custom paths that you want to be cleaned with the CST keyword:

$MONGO_BASE/etc/housekeeping.conf

CST::/u01/app/mongodb/local/dmk/logs/js/*.js::DELET::1:: # Delete JS files older than one day, to clean DMK internal folder.

For MongoDB log file, you should use the logrotate utility and not the housekeeping.py tool !
