IMAP Files on the Collector
Hi,
I am seeing these .imap files on the Dynatrrace Collector box which are taking up a lot of space. i wanted to check what these files are used for and is it safe to remove them if they are really old?
Hi
Yes - these represent our "Inheritance Map" - hence - IMAP. Our collector needs this for correct instrumentation. This inheritance map is built-up by analyzing byte-code of your applications. we keep record of the full inheritance hierarchy of your applications.
Please keep them there - otherwise you could break correct code instrumentation
Andi
But they are as old as October 2012. So they get accessed only when needed or how does it work?
They are only updated when there is new/updated inheritance information from your loaded java / .NET Code. If your application doesnt change significantely we wont update these IMAP Files as they are still accurate.
Which version of dynatrace do you run? in recent versions we implemented cleanup tasks for imaps that are no longer used or outdated
We use the 4.2 version. We are working to get it updated. I see a blobs.dtsf file which is taking around 14 GB space. What is the purpose of that file?
