When to Use This Chapter
Use the chapter for a brief description of the Event Management Service (EMS) and the tools used
to monitor EMS event messages.
What Is the Event Management Service (EMS)?
The Event Management Service (EMS) is a collection of processes, tools, and interfaces that support
the reporting and retrieval of event information. Information retrieved from EMS can help you to:
• Monitor your system or network environment
• Analyze circumstances that led up to a problem
• Detect failure patterns
• Adjust for changes in the run-time environment
• Recognize and handle critical problems
• Perform many other tasks required to maintain a productive computing operation
Tools for Monitoring EMS Event Messages
To view EMS event messages for an NonStop system, use one of these tools:
• “HP SIM Event Status Column and Event Tab” (page 77)
• “OSM Event Viewer ” (page 77)
• “Web ViewPoint” (page 78)
• “EMSDIST” (page 78)
HP SIM Event Status Column and Event Tab
From the HP SIM All Systems screen, the ES (Event Status) column displays aggregate event status
with a summary of all uncleared events. Event status is cleared whenever an event is added,
updated, or removed.
To view the events for a selected system or subsystem, click on the Events tab from its HP SIM view
page.
For more information, see HP SIM for NonStop Manageability.
OSM Event Viewer
The OSM Event Viewer is a browser-based event viewer. The OSM Event Viewer allows you to
retrieve and view events from any EMS formatted log files ($0, $ZLOG, or an alternate collector)
for rapid assessment of operating system problems.
To access the OSM Event Viewer, refer to “Launching OSM Applications” (page 30). For details
on how to use the OSM Event Viewer, refer to the online help.
