> Affects Versions: 2.4.0

> Script alerts, such as *Ambari Agent / Host Disk Usage* needs to have some
> metrics Externalized.
> The Usage screens relies on the alert_disk_space.py script to collect metrics
> such as Disk utilization (percentage) and directory being checked.
> The problem is that the directories being check in this script are:
> 1. ROOT ("/")
> 2. /usr/hdp
> If ROOT is OK, then "/usr/hdp" is checked subsequently. However if ROOT is
> NOT OK (>80% utilization) then "/usr/hdp" is ignored and the "CRITICAL" tag
> applies to ROOT.
> This would work on a OOTB standard cluster. However, many users, have
> Partitions for the hadoop directories. In this instance, "/" is static, no
> new content will be added. In this instance being at 80 or 90% is OK, this
> directory will never grow beyond that.
> "/usr/hdp" is a separate partition that grows in time.
> Based on the above described check, the 80% of the root partition will
> trigger a "CRITICAL" message, although the "/usr/hdp" partition is OK.
> The selection of what directory is being checked should be EXTERNALIZED to a
> configurable property to avoid these kinds of misleading messages.
> CONVERSELY --- what constitutes "OK" "WARN" or "CRIT" (the percentage that
> triggers these) should be left up to the user, not hardcoded in the script.
> This is a request to externalize the directories that should be checked, as
> well as the Percentages into an external configurable property.
