Splunk: Enterprise Operational Intelligence Delivered

Summary indexing

In a matter of days, Splunk will accumulate data and start to move events into the cold bucket. If you recall, the cold bucket is where data is stored to disk. You will still be able to access this data but you are bound by the speed of the disk. Compound that with the millions of events that are typical with an enterprise Splunk implementation, and you can understand how your historical searches can slow down at an exponential rate.

There are two ways to circumvent this problem, one of which you have already performed: search acceleration and summary indexing.

With summary indexing, you run a scheduled search and output the results into an index called summary. The result will only show the computed statistics of the search. This ...
