Naming Services dashlet

To diagnose and tune calls to naming service interfaces, the Naming Services dashlet displays data from the Java Naming and Directory Interface (JNDI) API. This AP provides Java applications with a unified interface to multiple naming (Lookup Names) and directory services. JNDI is also the basis for other important APIs, including RMI, EJB, JMS, and CORBA.

Metrics

The Naming Services dashlet displays the following information:

  • Platform: This unlabeled column displays an icon that identifies the software platform on which this particular name lookup was executed.
  • Look-up Name: The Qualified Lookup Name of the requested object.
  • Method: The method of the Naming Service component that was called to perform the name lookup.
  • Class: The class of the Naming Service component that provides the method used to perform the name lookup.
  • Agent: The name of the AppMon Agent that reported the name lookup invocation.
  • Count: The number of times this particular Naming Service method with this particular lookup name has been called or executed.
  • Total Avg [ms]: The average overall time, in milliseconds, spent to execute the Naming Service lookup.
  • Total Sum [ms]: The accumulated overall time, in milliseconds, spent to execute the Naming Service lookup.
  • CPU Avg [ms]: The average overall CPU time, in milliseconds, spent to execute the Naming Service lookup.
  • CPU Sum [ms]: The accumulated overall CPU time, in milliseconds, spent to execute the Naming Service lookup.
  • Exec Avg [ms]: The average overall time, in milliseconds, spent to execute the Naming Service lookup, excluding time spent in nested method calls.
  • Exec Sum [ms]: The accumulated overall time, in milliseconds, spent to execute the Naming Service lookup, excluding time spent in nested method calls.
  • Exec CPU Avg [ms]: The average overall CPU time, in milliseconds, spent to execute the Naming Service lookup, excluding time spent in nested method calls.
  • Exec CPU Sum [ms]: The accumulated overall CPU time, in milliseconds, spent to execute the Naming Service lookup, excluding time spent in nested method calls.

By default, not all metrics are included in the table. To select which columns to display, right-click a column head and select or clear the column check boxes as needed.
