IBM Streams 4.2.1

Using VMStat sample application to visualize data

Import the VMStat application to view data that flows through this application. The VMStat application reports virtual memory statistics at specified intervals.

Procedure

To import the VMStat sample application in Streams Studio:

  1. Click File > Import > IBM Streams Studio > Sample SPL Application, and then click Next.
  2. In the filter field, type vms, select the VMStat application, and then click Finish. Streams Studio imports the VMStat sample application into the Project Explorer view, creates a build configuration, and builds the application.
  3. Launch the application and provide a submission time value of 0.10 to generate 10 tuples per second.
  4. Open the instance graph for the VMStat application.
  5. In the Instance Graph view, find the VMStat job, right-click the stream that connects the two operators and click Show Data.
  6. Click Finish to retain the default settings.

Results

The Properties view opens and is pinned to the output port. The Data tab contains the current tuples. By default the tuples are updated every 3 seconds. In the Properties view, click Settings to experiment with the data. You can select different attributes, or change the buffering size, or add filters. You can also reorder the columns by dragging a column to a new location in the table.
