Data collection is a key aspect of any load test. For most tests this data comes from request metrics such as response time, error rate, throughput, etc<\/em>. However it is sometimes useful to capture data that is returned on the requested page itself. With JMeter<\/a>, this is possible using the Page Data Extractor<\/em><\/a>. This plugin can be used to directly plot data metrics returned from requests. Use cases include status monitoring, health checks, and other important data.<\/p>\n

The Page Data Extractor<\/em> plugin must be added to JMeter via the Plugins Manager<\/em><\/a>, which can be found under the \u201cOptions<\/em>\u201d menu. Installing the plugin for the first time will require a restart of JMeter:<\/p>\n

<\/a>Configuring the Page Data Extractor<\/h3>\n

To understand how the page data extractor works, it is best to illustrate by example. The scenario given in the Page Data Extractor<\/em> documentation<\/a> has requests going to a page with the following data metrics returned in the HTML body:<\/p>\n

\"Example
Example data available for extraction using the Page Data Extractor.<\/figcaption><\/figure>\n

This plugin uses regular expressions<\/a> to find and match elements within the page body. In his example, the expression (serv.*)=<\/strong><\/code> is used to extract a key, and the expression serv.*=(.*)<BR><\/strong><\/code> extracts the corresponding value:<\/p>\n

\"Example
Example configuration for the Page Data Extractor based on regular expressions.<\/figcaption><\/figure>\n

Running the test with an HTTP Request sampler<\/em><\/a> gives the resultant graph output. The same information can also be displayed as data rows from the \u201cRows<\/em>\u201d tab making it more conducive for export and further analysis.<\/p>\n
