Management Programming Interface
As shown in Figure 1-9, a management application in the operations environment uses
the management programming interface to monitor and control objects in the
PATHMON environment. The management application sends commands and
inquiries to processes in the PATHMON environment through the management
programming interface. The processes send responses or event messages to the
management application using the same interface.
Distributed Systems Management
The Distributed Systems Management (DSM) set of products is designed to monitor
and control every element of a distributed network, including PATHMON-controlled
objects in a Pathway environment. DSM incorporates a three-part architecture:
•
Operations environment
The operations environment includes your management application, which resides
in the same run-time environment as standard Guardian applications. The
application can be written in languages such as COBOL, C, TAL, and TACL.
•
Management programming interface
The management programming interface provides the standard set of procedures,
definitions, and message formats required to send messages between your
management application in the operations environment and the PATHMON
process in the Pathway environment. The management programming interface
includes SPI and the Event Management Service (EMS), another DSM facility.
EMS provides collection, logging, and distribution of event messages, which are
noteworthy occurrences such as state changes in objects or component failures.
The PATHMON process reports events to an EMS collector process, which logs
the events in an event log. An EMS distributor process reads the log and
distributes the events to all appropriate management applications.
