ULTRIX-32 Guide to the Error Logger System

This document, the "ULTRIX-32 Guide to the Error Logger System" (Version 3.0), provides comprehensive information on how to manage, maintain, and analyze error and event information on MicroVAX or VAX systems running ULTRIX-32.

The guide is primarily intended for system managers and Digital service representatives.

Key aspects covered include:

• Error Logger Overview: Details the system's core components: the kernel buffer (temporary error message storage), the elcsd daemon (which transfers messages from the buffer to permanent log files), and the elcsd.conf configuration file. It also explains how the error logger operates during various system states, including local crashes and remote system interactions.
• Management and Maintenance: Describes manual control of error logging functions using the eli command (e.g., enabling/disabling logging, clearing the buffer, restarting the daemon). It extensively covers reconfiguring the elcsd.conf file, including parameters for logging status (local, remote, server/client), errorlog file size, and various directory paths. Procedures for backing up and clearing errorlog files, and how to respond to crucial error logger system messages, are also outlined.
• Error Report Formatter (uerf): Explains how to use the uerf utility to generate and format error reports. This includes formatting options (brief, full, terse), and various ways to select specific errors or events, such as by file, host system, real-time occurrence, reverse chronological order, or by specific error types (adapter, class, disk, mainframe, operating system, tape) and criteria (record number, sequence number, time range), or by excluding certain error types.

In essence, the guide empowers users to understand system issues, troubleshoot problems, and maintain the integrity of their ULTRIX-32 systems by effectively utilizing its error logging capabilities.
