NTA Retention Period

kange0010

This is for NTA 4.2.0

Retention period is currently set to 30 days and has been like this for some time.  What will the impact be if I change this to 90 days?  When I press "CALCULATE" in the Database Size section, it shows:

Current size: 3.2 GB

Projected size: Retention period is full, see the current database size

So if I change my retention period to 90 days, will my current size be increased to 9.6 GB (3.2 * 3 = 9.6)?  Other than taking up more database storage, will there be more lag, loading time, etc regarding NPM and/or the web console?  I would really like to know before making the change.

I think you've largely got this answered, but wanted to provide some information for your question here.  When I calculate a changed retention size I find that I have to save the change and then hit calculate to get updated information.  I would stand by your estimation, but you will want to keep in mind that moving any variables (more flows, more devices sending flows, etc) will move that estimate.  As mentioned by Mesverrum in your other thread, under  50GB is small for NTA so you shouldn't have any major issues with standard hardware.
