Problem

Stats data under "/opt/zimbra/zmstat" is taking large disk space.

ZCS server does not purge the stats data automatically, and retention for zmstats is controlled by the localconfig key "zmstat_max_retention"'.

By default zmstat_max_retention is set to 0 (zero), and because of that "zmstat-cleanup" command is giving following warning.

zimbra@mail:~$ /opt/zimbra/libexec/zmstat-cleanup
WARNING: zmstat_max_retention is set to 0 or is undefined.  No zmstat data has been pruned.
zimbra@mail:~$ 


Solution

These are the available options with the zmstat-cleanup.

zimbra@mail:~$ /opt/zimbra/libexec/zmstat-cleanup -h
Usage: /opt/zimbra/libexec/zmstat-cleanup [-k <keep count>] [-h] [-l] [-p]

    -h|--help    Help/usage information
    -k|--keep    Number of archived copies of zmstat data to retain.
    -l|--list    Generate a listing of log dates archived.
    -p|--purge   Purge ALL archived zmstats data.


To keep zmstats data of a time period without changing the localconfig key, run:

Syntax:

/opt/zimbra/libexec/zmstat-cleanup --keep "<number of days>" 


Example:

Keep zmstats data of 300 days.

/opt/zimbra/libexec/zmstat-cleanup --keep 300
