Thread dump of an application through Wily

[Legacy User]

If I take thread dump through Investigator of an application/agent it shows me on the screen.

Where is it exactly saved on Wily cluster and what should be the file name ?

Hi,

 

They are stored on the Collector that the Agent is reporting to.  By default, the name of the directory is threaddumps.  So the path would be <EM Home>/threaddumps.

 

This can be modified by going to the IntroscopeEnterpriseManager.properties file and modifying the following property.

introscope.enterprisemanager.threaddump.storage.dir

 

So if your Agent is on Collector #2, you would go to Collector 2's threaddump directory and it is there.  Also while you have the Investigator up, after you collect a thread dump, you can also save it as a tda file and put it in another location.

Thank you Matt and Kristen,

          I had looked into  a few of the collectors and was hoping that the file was rotating.

          But it is on an specific collector, I think because it goes to that collector.

          Now I am looking for a tool which can help to read these binary files.

           Thanks again.

Hi Vijay,

The thread dumps generated by APM are best viewed within the Investigator and you might hit errors with an external tool

More info on this topic in the wiki e.g.

Configure Java Agent - CA Application Performance Management - 10.2 - CA Technologies Documentation

"Generate a Thread Dump Using the Command-Line Workstation

Note: To see the full thread dump stack, load it into the Investigator and view with any other external thread analysis tool. Using an external tool might result in errors."

Hope it helps
