warning interval 1h

zmlocalconfig -e zmstat_disk_interval=3600 

Configure disk monitoring thresholds using the '-e' flag for zmlocalconfig. For example, to set warnings to 90% and critical alerts to 98%:

zmlocalconfig -e zmdisklog_warn_threshold=90
zmlocalconfig -e zmdisklog_critical_threshold=98

Restart the Zimbra stat service for the new threshold values to take effect.
