Using ASAP
ASAP (Compaq NonStop™ Availability Stats and Performance) allows many subsystem
entities to be monitored across a network of NonStop Himalaya servers. The status and
statistics for the entities are collected on a single system, and are then monitored either
through the ASAP command interface or through the ASAP graphical user interface
(GUI) PC client.
RDF/IMP and IMPX are instrumented to feed state information to ASAP, thus allowing
RDF subsystems to be monitored, in an integrated way, alongside all other subsystems
supported by ASAP. The following RDF entities report state and statistical information
to ASAP:
•
Monitor
•
Extractor
•
RDFNET (optional)
•
Receiver
•
Purger
•
Updater
Architectural Overview
RDF/IMP and IMPX are supplied with an object file called ASAPRDF which is the
ASAP/RDF Smart Gatherer Process (SGP). SGP is the interface between ASAP and the
RDF environments. For every system in which ASAP is configured to collect RDF data,
the ASAP monitor starts an RDF SGP process. Figure E-1 shows a single RDF
environment replicating from \PRI to \BAK.
To monitor an RDF environment using ASAP, you must configure an RDF SGP on both
the primary and backup RDF systems. The SGP on the primary system reports data for
the monitor and extractor processes. The SGP on the backup system reports data for the
image trails and receiver, purger, and updater processes.
At regular intervals, the SGP process reports the status of each RDF entity residing on
that system to the ASAP collector (not shown). The ASAP collector writes the RDF
status information into the ASAP database, from which ASAP can be used to display
and monitor the status of the RDF environment. Refer to the ASAP Server Manual and
the ASAP Client Manual for details about how to monitor ASAP entities.
