Create a Service Profile

Follow these steps to create a profile and collect Java service profiling data.

Access the Service Profiler Page

1. In the Pulse UI, go to Service Profiler from the left navigation bar.

2. On the Service Profiler page, click Create Profile.

Enter Basic Information

Provide the general details for the profiling job.

• Name: Enter a name for the profile.

• Description: Provide a brief description of the profiling task.

Configure the Target

Select the service, component, and host where profiling will run.

• Service: Select the service to be profiled.

• Component: Choose the specific component within the service.

• Host: Select the host on which to collect profiling data.

Configure Profiling Parameters

Specify how Pulse should collect profiling data.

• Event Mode: Select the event type to profile. (Currently, only the CPU is supported.)

• Interval (ms): Define the sampling frequency in milliseconds. The default value is 10 ms.

• Timeout (seconds): Specify the profiling duration in seconds. The maximum value you can set is 7200 seconds (2 hrs).

Configure Output

• Format: Select the output format for profiling data.

• Currently supported: JFR (Java Flight Recorder)

Advanced Configuration (Optional)

You can fine-tune profiling by including or excluding specific Java classes and adjusting stack trace depth.

• Include Pattern: Specify Java packages or classes to include.

• Exclude Pattern: Specify Java packages or classes to exclude.

• JStack Depth: Define the depth of stack traces captured by JStack.

These options help narrow profiling to relevant parts of your application and minimize noise in the collected data.

Example Configuration

Next Steps

After the profile is created and executed:

• View the JFR file path from the Pulse UI. You can check the actual file on the node where the profile request was created.

• Analyze the data to identify CPU bottlenecks.
