Auto launch an user defined query [message #1828780]

Currently, MAT has the ability to auto launch the leak suspect query, I am wondering if there is a way to define my own.

We use MAT not only to address memory issue, but also at times, we'd like to have the process information available right after parsing complete.

This will save a manual query and user waiting time after a very long parsing.

I'm not sure whether you are talking about batch mode or GUI mode.

In batch mode it shows running a built-in report as

./mat/ParseHeapDump.sh myheapdump.hprof org.eclipse.mat.api:suspects

where the report or reports here are given as a plugin defined report. You can also give a path to your own XML report file.

In GUI mode the 'Getting Started' wizard choices are fixed.

Leak Suspects Report
Component Report
Re-open previously run reports

Those are not run automatically - the user needs to chose one or cancel it.

The user can then select a report from the 'Run Expert System Test' menu.

The overview page also has some links to run reports. See 361695: Proposed patch to add report extension to Overview pane for how reports starting with the name 'supplement_' are added to this page.

Thanks Andrew.

I am suggesting to auto run a user defined query if user choose to in UI.

For example

[x] Process Information (user defined)
• Leak Suspects Report
• Component Report
• Re-open previously run reports

[x[ means auto run.

Understand the batch mode and we are using it.
