How to create a summary index for my csv file

[JoshuaJohn]

On a daily basis I have a CSV loaded into splunk. I want to create a summary index so that this CSV will have historical data. Currently this file overwrites itself daily.

I have access to savedsearches.conf

Is there a tutorial for this somewhere, or a template I can follow?

This should give you details of summary indexing process.

Again, the traditional use for summary indexing is for optimizing searches/reports/dashboards, but it can be used for your use-case. You don't have to use any SI commands, so you can use use the like this (assuming CSV you upload as lookup)

| inputlookup yourUploadeda.csv
