ASAPXMON

The ASAPXMON processes execute in each processor where an application process

resides. They allocate the shared memory and parcel out segments of the memory to

application processes and are responsible for metrics production, objective analysis

and state production.

The application processes register with ASAPX by making a library call to the

ASAP_REGISTER_ procedure. The ASAP_REGISTER_ procedure communicates

with the ASAPXMON process in the appropriate processor to obtain the space offset

within the memory segment for the set of metrics representing the execution domain

specified by the calling process. If the procedure call is successful, a return code of 0 is

passed back to the caller, or an error is returned when the registration with the ASPAX

monitor is not successful.

ASAPXSGP

The ASAP Monitor starts the Statistics Gathering process for ASAPX. ASAPXSGP acts

as the interface to ASAP Server and is responsible for starting and managing the

ASAPX environment. There is one ASAPXSGP process per node. The SGP process is

part of ASAP and is started and managed by ASAPMON. The ASAPXSGP coordinates

the gathering of statistics and operational state information at each interval.
