I have recently installed Web Analytics for our ihs logs (sourcetype=access_combined) from LINUX servers. While setting up in Lookup section I had considered Generate user sessions and Generate pages for last 30 days.
1) With the selection Time Period as All time and Show by as "Day", when I had seen data in Traffic Center (Request Count by type), it is showing last 3 months - Why? ( fyi, the retention policy of the relevant index is one year). Can it not go beyond 30 days? Also, I expected the data for only 1 month as I set the lookup for last 30 days, why its showing for 90 days!
2) As understood, the data is first being stored KV store. How can I control the retention policy of for KV store. I do not want the capacity goes beyond it's limit. Also, I can I find out the current size limit and space left for the KV store?
The KVstore cleans itself out whenever it add new sessions every 10 minutes in the scheduled search. No need to do anything at all. This process is described in the docs for the app.
I have got the answer as below myself. Please feel free to comment/add to this.
1) The number of days is controlled by Data Model Acceleration set up. After changing the set up to 1 year, I started getting data beyond 90 days
2) Again, the data retention is dependent on the Data Model Acceleration set up. I have set up for 1 year.
