Using the Visualizers

File Visualizer

The file visualizer saves sampling data to a file of your choice. To use: The data saved in the file is a list of URL's followed by the number of milliseconds the response took.

Graphing Visualizer

The graphing visualizer displays every sample as a point on a graph, where the x-axis plots individual samples, and the y-axis measures time in milliseconds. As the graph accumulates points, JMeter draws an average line, and a standard deviation line.

Email Notification Visualizer

The email visualizer sends an email to one or more email addresses when a URL fails. It will also send email again if the URL begins working again. You can choose the subject lines that are used for each message.

Spline Curve Visualizer

Windowed graphing Visualizer

Scrolling Bars Visualizer

This visualizer shows samples as vertical columns, the height of which indicates how long the sample took. These vertical columns scroll by from right to left as more samples are taken.

Text Results Visualizer

This visualizer displays the text that was received back from the sample. After each sample is received, sampling stops to give you a chance to review the results, after which you can hit the "continue" key for the next sample. Use this visualizer to verify that JMeter is getting the results you expect. It is best used with just a single thread.
