beginSample(libraryName: String; initializationParameter: String): Integer;
The
NodeSampleInfoCallBack, passing it the initializationParameter string and setting the eventType parameter in the user library entry point to 1.
NodeSampleNodeInfoCallBack, passing it information about the local node and setting the eventType parameter in the user library entry point to 1.
NodeSampleProcessInfoCallBack, invoked every time that a process begins and once for every existing process at the time sampling begins.
This method returns the sampling handle number used to identify the sampling context that is opened. All subsequent methods use this sampling context handle as the first parameter.
When the beginSample method is called in your application, request statistics are stored in transient memory for every process in the node until they are passed to a corresponding entry point in the user library specified in the libraryName parameter.
The JADE-supplied library writes a record type (6) to the statistics file. For details about the node sampling entry points and the contents of the statistics sample files, see "JADE Sampling Libraries" and "Statistics File Format", later in this chapter.
If you are using the filesmpl or tcpsmpl JADE sampling library, you can set the initializationParameter parameter to "<null>" or to "" so that sample values will not be output. For filesmpl, the values will not be written to a file.
For tcpsmpl, the values will not be sent to a TCP/IP connection. Use this option in situations where node sampling needs to be enabled for the
