Hello @Hema k.

Open the Session Browser dashlet in case the Leak Analysis Memory Snapshot triggered.

https://www.dynatrace.com/support/doc/appmon/appli...

Also you can use the RESTful interfaces to manage memory dumps.

Hello @Hema k.

It means there was no memory leak on the 20th. Open the incident dashlet > right click on the incident > select the details and share the exact message.

Hello @Hema k.

The memdump stores in the session storage > system profile. I am wondering that the required memdump is not available otherwise you would see in the Session Browser dashlet.

You can also use a below request URL to get a list of all memory dumps for the specified System Profile.

Hello @Hema k.

By defulat the Leak Analysis Memory Snapshot automatic generation, and Trending/Leak Analysis Memory Snapshot creation for .NET CLRs is enabled.

In the Labels Column of the Session Browser dashlet you can see the message e.g. Automatically triggered by Out-of-Memory notification at Wed Apr 25 17:41:53 AST 2018

Have a look on the below link for more insight.
