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.
