Amazon elasticsearch interpretation of FreeStorageSpace metrics

I have 6 instances of type m3.large.elasticsearch and storage type instance.

enter image description here

I don't really get what does Average, Minimum, Maximum ..mean here?

I am not getting any logs into my cluster right now although it shows FreeStorageSpace as 14.95GB here:

But my FreeStorageSpace graph for "Minimum" has reached zero!

What is happening here?

Solution

  • I was also confused by this. Minimum means size on single data node - one which has least free space. And Sum means size of entire cluster (summation of free space on all data nodes). Got this info from following link
