Level: Major

Purpose: Identify when there is only 20% or 10% of disk space left

Scenario: Major - Disk usage on <server> has been more than 90% for 5m. Minor - Disk usage on <server> has been more than 80% for 5m.

Resolution: Check free space on server: “df -h” & remove any large temporary files

sudo du -sxh /* 2>/dev/null | sort -h

Above command is useful to pinpoint which folder has most space usage. Move into this folder and run again to see which folder inside has most space.. continue until you find the source.

Manual Action Steps: Temporary files include DB dumps, heap dumps, large files in temp or backup directories.

Auto Clear: Will clear when disk space is lower than 90%/80%
