Eventhough we have given 300GB of disk space to store the data it is not even holding 20 days of data. Is there anyway to store atleast 3months of purepath data in any format and how can we restore it back when it is necessary.
Retention time is based on first in first out. The more traffic the shorter your generic "retention". You can export sessions (pick a time slice) off to another storage location, or increase your storage. We find our sweet spot Is around 2.5TB and that gives us around 12-15 days. Please keep in mind that every purepath dashlet you use will suffer performance degradation the larger the session you're analyzing. So the more purepaths you store, the worse your client will behave to the point of unusable. Good luck on finding the right settings for you.
There's a great video in the apm university about sessions. here's the link:
If you haven't had the chance browse through some of the other videos that may shed light on other functions you might have been wondering about. Dynatrace puts a lot of effort into making some quality education materials.
Hi Praveena, The session storage (actual PurePaths) depends upon the production traffic ie. purepath data generated. More the data more the session storage will be required. If this is insuffience you need to re-size your production storage. Look here.
Also, I guess 2TB is soft limit on the practical usage of session. You should also consider your requirements with respect to Performance Warehouse data.
