MPH REL NOTES.PDF

The document describes Monitoring Performance History (MPH), a voluntary system monitoring tool that is part of Digital's Digital Product Performance (DPP) Program.

Purpose: MPH aims to improve the reliability and availability of Digital systems by collecting performance data from participating customer and Digital sites.

How it Works:

• MPH resides on participant systems with negligible impact on performance or security.
• It collects error log entries, crash dump summaries, and configuration information.
• This data is automatically sent weekly to the DPP group via mechanisms like DSNLink or Internet mail.
• DPP analyzes the information and generates reports for Digital's engineering, manufacturing, and services teams to improve system reliability.
• All collected data is classified as Digital Confidential and used for internal purposes only.
• The process is fully automated, runs as a background task, and requires approximately 300 blocks of disk space.

Key Features/Updates in Version 1.4:

• Offers upgrades to existing installations.
• Allows error log data collection on a weekly or daily basis.
• Includes improved space management to prevent impact from large error logs.
• Provides safeguards and warning messages, notifying system managers about DSNLink problems or large error log changes.
• Enables adding or deleting monitored nodes in a cluster post-installation.
• On field-test OpenVMS systems, it may also install Remote Performance Monitoring Software (RPM) to gather performance trend data related to reliability.

Management: MPH can be installed, stopped, and deinstalled using specific system commands. Participation is voluntary and requires no special maintenance agreement.
