flow-expire(1)                       General Commands Manual                       flow-expire(1)

NAME

       flow-expire — Manage storage of flow file archives by expiring old data.

SYNOPSIS

       flow-expire [-h]  [-d debug_level]  [-e expire_count]  [-E expire_size] -w workdir

DESCRIPTION

       The flow-expire utility will remove the oldest flow files in a directory based on either a
       count of files or space utilization.  The  directory  is  recursively  searched  for  flow
       files.   Files  that  do  not  have  a flow-tools signature will be ignored.  The internal
       timestamp is used so backups or copies of the flow files that do not retain  the  original
       timestamp  will not impact the operation of flow-expire.  flow-expire is typically used to
       manage storage in a distributed environment where  flows  are  collected  on  a  different
       server than they are archived.

OPTIONS

       -d debug_level
                 Enable debugging.

       -e expire_count
                 Retain  the  maximum  number  of files so that the total file count is less than
                 expire_count.

       -E expire_size
                 Retain the maximum number of files so  that  the  total  storage  is  less  than
                 expire_size.  The letters b,K,M,G can be used as multipliers, ie 16 Megabytes is
                 16M.

       -h        Display help.

       -w workdir
                 Work in workdir.

EXAMPLES

       Remove the oldest flow files in /flows/krc4  until  the  total  storage  is  less  then  2
       Gigabytes.

         flow-expire -E2Gig -w /flows/krc4

       Remove  the  oldest flow files in /flows/krc4 until the total number of files is less then
       100.

         flow-expire -e100 -w /flows/krc4

BUGS

       Empty directories are not removed.
