There is currently no way to change the directories which are checked by this alert. The alert
is mostly concerned with the free space where stack components are installed (either /usr/hdp
or /usr/lib).

You can easily create another alert script to check a different directory if desired.

Good Morning!!

I am as well facing same issue where Ambari alerts with the disk usage alert. However, I would
want to understand on the process much before the alerting process i.e. the allocation of
disk space itself. Suppose I had 2 volumes mounted /dev/sda1 which is 50GB and /dev/sda2 which
is 1TB.

Now when I install HDP with these two volumes, HDFS space is correctly allocated i.e. /dev/sda2
is given for HDFS. However, I believe /dev/sda1 is used by Ambari for its internal storage.
As in my case /dev/sda1 has other data as well, including OS, it is obviously less in disk

Can anyone please let me know how to configure Ambari to use disk space of my choice rather
than auto selecting the smaller partition?

Thanks & Regards

The Ambari Agent Disk Usage Alert is a SCRIPT type alert.

It's thresholds are not configurable in the Ambari Web UI you can modify via the API.
