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.
