Ambari agent disk usage alert: Remedy?

[#1]

What are the necessary steps to be taken when we get ambari agent disk usage warning alert on timelineserver(history server ) ?

[#2]

@Ram D

run "df -h" to find out the mount points with most used disk space.

then run "du -hs *" to get the directory with most used space. Then start purging whatever is not necessary or move to another directory or compress.

@Ram D making sure that it's not false alert or there is enough space but threshold needs to be set properly.
