Configuration of AppPoolWorkerTest

This test periodically monitors the overall status, resource usage, open handles, and I/O activity in each application pool on an IIS web server; in addition, the test also captures and reports operational issues with the worker processes that service requests to an application pool, thereby shedding light on the contribution of worker processes to slowdowns/outages that a web server suffers.

The default parameters associated with this test are as follow:

  • 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 component for which the test is to be configured has to be specified.

  • Specify the port to which the specified HOST listens in the PORT text box.

  • By default, the WEBSITE NAME parameter is set to none. This implies that the test monitors all web sites, by default. If you want the test to monitor a specific web site alone, then specify that web site name here.

    Note:

    If this test is configured with a web site name, then all other web site-related tests of the target IIS web server will report metrics for this web site only.

  • If a request is processed for a period equal to or more than the duration (in second) specified in SLOW REQUEST CUT OFF, then such a request is counted as a slow request. By default, the slow request cut off is 4. This means that, by default, the test will report all requests that take 4 seconds or more to be serviced as slow requests. You can override this default setting by specified a different cut-off value here

  • 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.
