All day, I've been watching the amount of events indexed in Splunk go up and down. It stays in the 1.8-1.9 billion events range, but it's going up and down. Saw it at 1.96 billion today, and then it went down to 1.93 back to 1.96 and now 1.89. Is there a default setting somewhere I need to look at?
Check out settings in indexes.conf
. As buckets roll from cold to frozen, they will be removed from the index and the indexed event count will go down by the number of events in the bucket.
