Sample Debugging: Adding Breakpoints

Use the esp_client command-line utility to add or delete breakpoints from a stream or window. Pause the Event Stream Processor before adding a breakpoint.

1. Add a breakpoint on a stream, before it starts processing an input record from any stream using:

   bp add `stream` any

2. Delete the breakpoint with specified ID using:

   bp del `id`

   The ID of a breakpoint is given by using either the bp add or bp list commands.

3. Delete all breakpoints using:

   bp del all

4. Enable or disable a breakpoint with specified ID using:

   bp on|off `id`

5. Enable or disable all breakpoints using:

   bp on|off all

6. Make the breakpoint with specified ID trigger on every nth occasion.

   bp every `count` `id`

7. Make all the breakpoints trigger on every nth occasion using:

   bp every `count` all

8. List all created breakpoints using:

   bp list

• Sample Debugging: Adding Conditional Breakpoints
  The esp_client command-line utility provides options for adding conditions to a breakpoint. These breakpoints trigger only when the condition evaluates at true.
