Hi,
Can someone clarify the difference between the cumulative raw data size found in the cluster settings on a splunk master and the index disk usage for an index in Splunk SOS. The disk usage value in SOS is about three times larger than the value for cumulative raw data size. Currently on Splunk 6.0.3.
I am seeing the same behavior. Actual size on disk is atleast 10 times larger than the cumulative raw data size. Any further updates on this question?
As far I understand the cumulative Raw is actually the raw data indexed itself. The Index Disk Usage is the raw data indexed and everything else Splunk creates/saves to disk for that specific index.
In may case it's normally the opposite, the space in disk is 3 times smaller in most of my indexes. I believe it depends on data compression and field extraction (during indexing phase).
