I'm trying to understand how session storage manages data aggregation (if it does any) and how to work out how long low resolution data is kept in session storage.
I understand that the performance warehouse has the following configurable aggregation settings for storing the various levels of resolution:
Is there something similar for session storage, or does it simply continuously overwrite whenever the session storage limit is reached?
if you right click in your system profile and select details you will be able to see how far back the PP are being kept. Example:
Now, if you have multiple system profiles you will have to check for each one and if you want keep more days for one app than other you can reserve space by system profile under Settings>Dynatrace server settings> Storage and under disk quota reservation per system profile add the desired system profile:
This will also tell you Since when do you have data for that system profile.
I hope this helps.
