Configuration of ZingJvmMemoryUsage

This test monitors the memory usage of an application running in the Zing VM and reports how that application is utilizing the different portions of the host system's memory resources - this includes System Linux Memory usage, physical memory usage, and System Zing Memory usage. In the process, the test captures and alerts administrators to memory bottlenecks and also pinpoints where the root-cause of the bottleneck lies - is it in the System Linux memory usage? physical memory usage? or System Zing memory usage?

If abnormalities are noticed in the application's System Zing memory usage, then the test provides deeper insights into the System Zing memory portion by reporting how the application is utilizing the Reservable, Pause Prevention, and Contingency memory pools of the System Zing memory. This way, the test accurately isolates that memory pool from which the maximum System Zing memory resources are drained.

Moreover, in the event that the System Zing Memory is used erratically, the test also leads you to the exact process running on the Zing VM that is consuming maximum memory.

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

• In the PORT text box, enter the port number at which the specified host listens.

• To make diagnosis more efficient and accurate, eG 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, by default, for a particular server, choose the Onoption 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 default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
