Set Tracepoint

Setting up a tracepoint helps developers understand code execution on specific parts of an application. It’s as easy as setting up an ordinary line breakpoint with just one click on the gutter area.
Since there are multiple types of breakpoints that can be set on that line, namely a Java breakpoint and a Thundra tracepoint, IntelliJ IDEA will show you a small popup with a list of possible breakpoint types:
Thundra Sidekick - Setting up a Tracepoint
Note that the Thundra tracepoint option is only available if you are already connected and have clicked on a line containing a valid expression inside a Java method.
When you select “Thundra Tracepoint”, you see a gray tracepoint icon for a second until it is synced to the remote application, it then becomes yellow when the connection with the remote application is set.
Thundra Sidekick - Disconnected Tracepoint
Thundra Sidekick - Connected Tracepoint
Note that you are only setting a tracepoint to the application instances visible on the main Thundra tool window. So, the tracepoint can be created on multiple application instances once, but if an application instance is hidden on the main tool window, the tracepoint will not be created there.
If the tracepoint is created on all of the selected instances, you will see the following success message:
Thundra Sidekick - Tracepoint Success
If the tracepoint is created on some (but not all) of the instances, you will see the success message and error details together. For example, if you attempted to put a tracepoint on three instances, but two of them doesn’t contain the target class, you will see the following notification:
Thundra Sidekick - Tracepoints Partial Success
Note that the numbers indicate the instance counts where the corresponding error occurred. If the tracepoint couldn’t be created on any of the instances, you will see the following error message:
Thundra Sidekick - Tracepoints Fails
After setting your first tracepoint, you can start browsing the tracepoint events as explained here.
