Performance Monitor

The Monitor View shows visual indicators of queue size, throughput, and CPU use for each stream and window (including LOCAL streams and windows) in a project.

Each node corresponds to a stream in the model with the lines outlining the path the data flows through. The color of each node represents either QueueDepth or Rows Processed (/sec), depending on your specifications.

For example, if you select the Color Queue Depth option, the (Red) Range >= field defaults to 125, and the (Yellow) Range >= field defaults to 20. This means:

If the queue depth of the stream node is greater than or equal to 125, the node is red.

If the queue depth of the stream node is between 20 and 124, the node is yellow.

If the queue depth of the stream node is less than 20, the node is green.
If the nodes remain white, it indicates that the monitor is not receiving data from the stream processor.

The Monitor View also depicts CPU utilization as a black pie wedge in the ellipses of the node. Based on the options chosen, the remainder of the ellipses are red, yellow or green. A fully black node represents 100% CPU use, based on a single CPU core. With multicore or multiprocessor environments, a fully black node may be greater than 100%.

You can look at a specific node's performance statistics by moving your cursor over the node in the diagram.
