This is a CEPH 18/19/20 diagnostic script that gathers technical information to aid in rapid diagnostics. To install simply use deploy as

deploy install debugceph

Then you can run it, as root (or sudo) with

./debugceph.sh --upload <your helpdesk email>

This script creates a debugceph.txt file in the current directory, if you didn't use --upload then simply attach this to your ticket.
