The sampling of activities in JADE applications is produced at the node level. The JADE Object Manager invokes specified entry points in a user-provided dynamic library during its normal execution.
The user dynamic library can then process the information provided by the JADE Object Manager. For example, you could capture data to flat disk files for subsequent processing using a tool of your choice to obtain the operational profiles that you require.
The activities that you can sample enable you to understand the execution characteristics of runtime applications so that you can enhance application performance according to different hardware resources.
A JADE node can initiate sampling on any other node in the system. For example, a client node can sample statistics on another client node and the server node, or a server node can gather statistics on every client node that is attached to it.
When the JADE-supplied library is used, samples are output to your specified flat file, which must be visible to the node being sampled. These samples can then be gathered for subsequent analysis to meet your requirements.
You can use the JADE Monitor to analyze the contents of your node sampling files. For details, see the
