Review request for Ambari and Vitalyi Brodetskyi.

Bugs: AMBARI-13603

Repository: ambari


The alert "Ambari Agent Disk Usage" is causing some confusion for users: what
does it really indicate. The ambari disk usage alerts are meant to check two
things: that you have have enough space total and percent free space in
/usr/hdp for data created by hadoop and for installing versioned RPMs. Total
free space alerts are something that you’ll probably want to fix since it
means you have less than a certain amount of total free space left.

Proposing the change...

Alert Name:  
**Host Disk Usage**

**This host-level alert is triggered if the amount of disk space used at /usr/hdp goes above
specific thresholds. The default threshold values are 50% for WARNING and 80% for CRITICAL.**
