Event Messages
Introduction

Event Messages OSI/AS subsystem processes generate event messages when they detect significant
events, such as a trap caused by a hardware or software error, a failure to establish
communication with the Transport Layer, or a management counter reaching a
threshold. The subsystem processes send these event messages in SPI format to the
Event Management Service (EMS), which makes them available to management
applications upon request.
Section 6 of this manual describes in detail the contents of the event messages that the
TAPS and OSI manager processes issue. For descriptions of event messages that TSP
processes issue, refer to the Tandem OSI/TS Management Programming Manual. For
descriptions of event messages that NSP processes issue, refer to the X25AM
Management Programming Manual or the TLAM Management Programming Manual.
Event messages generated by all four types of processes can be displayed for system
operators using an EMS printing distributor or the ViewPoint console application. For
information about the use of EMS printing distributors, refer to the Event Management
Service (EMS) Manual. For general information about ViewPoint, refer to the ViewPoint
Manual. For descriptions of the displayed form of these messages, refer to the manual
Operator Messages: Distributed Systems Management (DSM) Display Format.
