ASAP Extension Architecture

Through the ASAP Extension, you can extend ASAP collection and presentation

functions to your own applications. The ASAP Extension provides an Application

Programming Interface (API) so you can add customer application metrics to the ASAP

infrastructure.

Applications use ASAPX by calling the ASAP_REGISTER_ API procedure to register

with ASAPX. That procedure communicates with the ASAPXMON process in the

processor where the application resides to register and obtain the shared memory

offset for the application domain. The applications then call one of the API update

procedures to update their statistics directly within shared memory.

At the ASAP-defined statistics interval, the ASAPXSGP process prompts each

ASAPXMON process for the domain metrics from that processor. ASAPXSGP or the

ASAPXMON processes then forward the statistics to the ASAP Collector process on

the collection node.
