14 The flow-expire utility will remove the oldest flow files in a direc‐
15 tory based on either a count of files or space utilization. The direc‐
16 tory is recursively searched for flow files. Files that do not have a
17 flow-tools signature will be ignored. The internal timestamp is used so
18 backups or copies of the flow files that do not retain the original
19 timestamp will not impact the operation of flow-expire. flow-expire is
20 typically used to manage storage in a distributed environment where
21 flows are collected on a different server than they are archived.
22
24 -d debug_level
25 Enable debugging.
26
27 -e expire_count
28 Retain the maximum number of files so that the total file count
29 is less than expire_count.
30
31 -E expire_size
32 Retain the maximum number of files so that the total storage is
33 less than expire_size. The letters b,K,M,G can be used as multi‐
34 pliers, ie 16 Megabytes is 16M.
35
36 -h Display help.
37
38 -w workdir
39 Work in workdir.
40
42 Remove the oldest flow files in /flows/krc4 until the total storage is
43 less then 2 Gigabytes.
44
45 flow-expire -E2Gig -w /flows/krc4
46
47 Remove the oldest flow files in /flows/krc4 until the total number of
48 files is less then 100.
