Figure 1-1: ASAP Hybrid Components and Architecture
Each of these components has a specific role within the overall ASAP
infrastructure:
 ASAP Hybrid Linux API Library
The ASAP Hybrid Linux API Library provides the interface layer between Linux
applications and the ASAP subsystem. Applications link to this library and call
ASAP Hybrid API procedures in order to register domains and update metric
counters in shared memory. Both thread-safe and non-thread-safe versions
are supplied for most procedures. The thread-safe variants allow application
counters to be shared among multiple threads of a single process.
 ASAP Hybrid Linux Server
The ASAP Hybrid Linux Server is responsible for capturing application metrics
from the local Linux system and routing them to ASAP on the NonStop server.
It also monitors the domains registered on the Linux machine in order to
detect application failures and permit recovery of metric data.
