about the tape devices and tape mount requests on the node. The utilization counters
gathered include number of outstanding tape mounts and Label mode checks.
ASAPTCP Object File
The optional ASAP TCP/IP Plug-in Statistics Gathering (ASAPTCP) process collects
availability information for nine separate TCP/IP entities and three Telserv entities,
including availability, usage, performance, and connection information. The ASAP
Monitor starts the optional TCP SGP on its node if TCP is enabled.
ASAPTMF Object File
The ASAP Monitor starts the TMF SGP on its node if the TMF SGP is enabled. The
ASAP Statistics Gathering (ASAPTMF) Process collects availability information about
the TMF subsystem. Valid TMF domains are: Transactions, AuditTrail, AuditDump, and
TMF for the TMF subsystem itself. The utilization counters gathered include
percentage of audit trail used, transaction rate of the TMF subsystem, and number of
pending transactions. ASAPTMF communicates directly with the TMFServe server
process for obtaining TMF availability information.
ASAPXMON Object File
The optional ASAPX Monitor process (ASAPXMON) allocates and manages shared
memory in each processor and performs sampling and metric computation.
Applications use the ASAP_REGISTER_ procedure to communicate with
ASAPXMON. ASAPXMON allocates shared memory for the application and returns
the memory address used in subsequent calls to update procedures.
At each interval, ASAPXMON processes sample shared memory and computes
statistics for each application domain.
ASAPXMON processes are started and managed by ASAPXSGP.
ASAPXSGP Object File
The optional ASAPX Statistics Gathering Process (ASAPXSGP) initiates statistics
gathering at each interval and starts and manages ASAPXMON processes.
In normal operating mode, the SGP gathers statistics from all ASAPXMON processes
and forwards them to the ASAP Collector process. The SGP also performs aggregate
calculations across all ASAPXMON processes and creates any necessary aggregate
domain records.
In Write-to-Collector mode, each ASAPXMON writes directly to an ASAP Collector
process and only sends aggregate total records to the SGP.
ASAPXSGP is a standard ASAP SGP and is started and managed by ASAPMON.
