flow-expire — Manage storage of flow file archives by expiring old data.
flow-expire [-h] [-d debug_level] [-e expire_count] [-E expire_size] -w workdir
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.
