How to analyze Thread Dumps in Pega 8.8.0 VERSION?
Hi,
I can see, after Version 8 we dont have SMA for thread dump analysis from the previous support notes.
I wanted to know in version 8.8.0 How can we analyze Thread Dumps?
Because some of the Pega Alerts slows down the performance.
Thanks in advance.

Hi @MayadeviA: Please navigate to Admin studio -> resources -> API.
Locate the API GET /nodes/{nodeID}/diagnostics/thread_dump in v1 Pega API. Pass the node id as request parameter. Save the response as a zip file. Extract the zip file to get the thread dump as txt file.
Thanks.

@MayadeviA SMA has been removed from the product and replaced by Admin Studio in Pega 8.x.
When you configure an application server with the DB details and add a node type using -Dnodetype JVM parameter and start the server you will be able to see that node in the Admin Studio in System> System & nodes.
Admin Studio is a kind of replacement for SMA and is supposed to pick the nodes automatically to display.
You need to use Admin Studio, where a list of REST API are provided for certain functionality.
See a suggestion made here to use stand alone application for SMA. https://github.com/mishankov/pega-infinity-sma
Other answers can be found in Admin Studio - Need navigation steps similar like SMA
Also consider PDC as documented in Alerts overview

Thank you for your quick reply.
May I know where we can see Thread dumps in Admin studio.
It would be great if you could provide me the steps.

@MayadeviA The Admin Studio only monitors nodes.
If you have the Thread Dump downloaded / handy when the issue occurred, you could use: Smart Java thread dump analyzer - thread dump analysis in seconds (fastthread.io) to upload the available thread dumps and see by yourself about more details on the issue
You can take a look at external solutions here.
