Configuration of SlowTransTest

This test monitors user-configured transaction patterns, captures the response time of each configured pattern in real-time, compares these actuals with the desired levels of responsiveness (which is also configurable), and thus isolates and proactively alerts you to slow transactions. Note that, this test executes only on IIS web servers operating on Windows 2008, and does not execute on the IIS Web servers v8 and above.

Note:

To make sure that this test reports measures, do the following:

  • Configure a Web Server role on the target Windows 2008 server.
  • Install and configure Advanced Logging for the IIS web server operating on Windows 2008.

The default parameters associated with this test are as follows:

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.
  • In the HOST text box, the host name of the server for which the test is to be configured has to be specified.
  • Specify the port at which the specified host listens in the PORT text box.

  • Using the NAME, PATTERN and THRESHOLD VALUE text boxes, you can configure the URL patterns for the transactions to be monitored by this test. You can group a set of related/similar patterns under a common head - a display name for this group head can be provided in the NAME text box; this display name will appear as a descriptor of the test in the eG monitoring console. In the PATTERN text box, you can configure the transaction patterns that are to be grouped under the specified NAME. Multiple transaction patterns can be separated by a semi-colon. Wild card characters can be used while configuring these patterns. For example, to monitor all transactions with the extension html or jsp, your PATTERN specification should be: *.html;*.jsp. In the THRESHOLD VALUE text box, specify the response time value (in seconds), which should be violated, for a transaction to be counted as a 'slow transaction'. All transaction patterns grouped under a given NAME will be governed by the THRESHOLD VALUE specified.

    You can, if you so need, configure multiple display NAMEs, PATTERNs, and THRESHOLD VALUEs for monitoring. To enable you to configure the multiple values easily, the eG administrative interface provides a special page. To access this page, click on the Click here hyperlink, which appears just above the parameters of this test in the TEST CONFIGURATION PAGE.

  • To make diagnosis more efficient and accurate, the eG system embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option against DETAILED DIAGNOSIS. To disable the capability, click on the Off option.

    The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

    • The eG manager license should allow the detailed diagnosis capability

    • Both the bad and normal frequencies configured for the detailed diagnosis measures should not be 0.

  • If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

  • Once the necessary values have been provided, clicking on the Update button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
