Measures reported by SapWasAliasesTest

An application alias is an alternative name for a J2EE Web application running on the J2EE Engine. Each Web application has its own root as defined by the Java Servlet Specification version 2.3. It is also referred to as context path. The context path of a Web application is mapped to a URL pattern. Server users utilize this URL pattern to access the resources of a particular Web application. The application alias actually represents the URL pattern that is mapped to a certain application’s context path. If too many aliases are inactive or not available, then the users may experience difficulty in accessing the web applications corresponding to the aliases. Therefore, it is necessary to monitor the application aliases round the clock.

This test auto-hujdiscovers the patterns of the aliases and for each pattern, reports the total number of aliases available and the total number of aliases that were inactive. In addition, this test reports the rate at which aliases of each pattern are retrieved upon user request.

Outputs of the test : One set of results for every Alias Pattern on the SAP WAS monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
total_aliases Indicates the number of responses of this type received by the server during the last measurement period. Number  
inactive_aliases Indicates the number of aliases in this pattern that were inactive. Number The detailed diagnosis of this measure lists the Application name and the status of the Ignore cookie.
avgreqrate Indicates the rate at which aliases of this pattern were retrieved upon a user request. Requests/sec A high value is desired for this measure.
