Starting accounting and statistics data collection in the WebSphere Message Broker Explorer

Use the WebSphere® Message Broker Explorer to start collecting snapshot accounting and statistics data for your brokers, execution groups, and message flows. You can then view the accounting and statistics data in the Broker Statistics and Broker Statistics Graph views.

Before you start:

• Ensure that you have created a message flow; for more information, see Creating a message flow.
• Ensure that you have deployed a broker archive (BAR) file; for more information, see Deploying a broker archive file.
• Read the concept topic, Message flow accounting and statistics data.

Use the snapshot accounting and statistics data displayed in the Broker Statistics and Broker Statistics Graph views to monitor the performance and resource usage of your broker or execution group at the message flow, node, or terminal level.

You can start collecting accounting and statistics data for an active broker at any time. You can start collecting accounting and statistics data for multiple brokers at the same time.

To start collecting snapshot message flow accounting and statistics data by using the WebSphere Message Broker Explorer:

1. In the WebSphere MQ Explorer - Navigator view, expand the Brokers folder.
2. Right-click the execution group or message flow for which you want to collect statistics.
   • If you selected an execution group, click Statistics All Flows > Start Statistics.
   • If you selected a message flow click Statistics > Start Statistics.
   A message is sent to the broker to start collecting accounting and statistics data for the selected resource.
3. Click Window > Show View > Broker Statistics to open the Broker Statistics and Broker Statistics Graph view. These two views are displayed together. If you close one of the views, the other view is also closed.

Accounting and statistics data for the selected broker, execution group, or message flow is displayed in the Broker Statistics and Broker Statistics Graph views. It can take up to 30 seconds for accounting and statistics data to be received from the broker and displayed in the Broker Statistics Graph view. The message Waiting for Data is displayed in the title bar is displayed until accounting and statistics data is received from the selected broker, execution group, or message flow. When data is received from the broker, it is displayed in numeric form in the Broker Statistics view, and a visual representation of this data is shown in the Broker Statistics Graph view. Select individual or multiple items in the Broker Statistics view to change the information displayed in the Broker Statistics Graph view.

Next:

To examine the current data in the two views, click Pause in the Broker Statistics Graph view to prevent the current data from being overwritten with new data. Click Play to resume displaying more accounting and statistics data. You can change the visual representation of the data by clicking Linear, Logarithmic, and Stacked.

You can also select the metrics that are displayed in the graph view; for more information, see Filtering message flow accounting and statistics data.
