Configuration of OsHandleTest

This test monitors and tracks the handles opened by processes running in a target host system.

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.

• The HANDLE GROWTH LIMIT defines the upper limit of the handles opened by any process. By default, this parameter is set to 100000.

• The detailed diagnosis of the Processes using handles above limit measure reveals the top-10 processes that are using handles above the configured limit, the number of handles used by each process, and the break-up of the handle count by sub-handles (i.e., the count of file handles, disk handles, etc.). For processes that typically open thousands of handles, storing granular, sub-handle-level information pertaining to these handles may impose additional strain on the eG database. In such cases, you can reduce the strain on the eG database by configuring in the IGNORE PROCESSES IN DD text box, a comma-separated list of process names/process patterns for which sub-handle-wise breakup need not be collected and stored in the eG database. The default value in this text box is *ccSvcHst.exe*. This implies that, by default, the detailed diagnosis of the Processes using handles above limit measure will only provide the total number of open handles for ccSvcHst.exe process, but not the sub-handle-level information. If required, you can choose to exclude the sub-handle-wise breakup from the detailed diagnosis for more processes by including these process names/patterns as part of the IGNORE PROCESSES IN DD specification. For instance, your specification can be: *ccSvcHst.exe*,*js.exe*,*java.exe*

• By default, the SHOW SUB HANDLES IN DD flag is set to No indicating that this test will not report sub-handle details as part of its detailed diagnostics, by default. This setting will help you to conserve space in the eG database. However, you can set this flag to Yes if you want to see the sub-handles opened by each of the top-10 processes in the detailed diagnosis. To this effect, the Top 10 Open Handles column will be populated with relevant information in the detailed diagnostics reported for the Processes using handles above limit measure.

• In the EXCLUDE PROCESSES IN DD text box, specify a comma-separated list of processes that should be excluded from the scope of reporting as part of the detailed diagnostics of the Processes using handles above limit measure. For instance, your specification can be: *ccSvcHst.exe*,*js.exe*,*java.exe*.

• To make diagnosis more efficient and accurate, the eG Enterprise 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. 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 normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

• 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.
