Fault and Performance Management

Fault and performance management includes the following topics:

• Monitoring Alarms and Events

• Launching the Event Browser

• Viewing Cisco MGM Logs

• Registering Cisco MGX 8260 Traps

• Monitoring Alarms from the Cisco WebViewer

• Monitoring Performance from the Cisco WebViewer

Alarm Management

The Cisco MGM Alarm component, which is a customized component of the CEMF3.1 platform, handles Cisco MGX 8260 Media Gateway alarms and events. Cisco MGM receives alarm and event messages from managed objects and displays them in the Map Viewer and Event Browser. The Map Viewer displays alarms on the topology view, and the event browser displays events in tabular form. The tabular data includes severity, date, source, and other information.

Cisco MGM implements alarm features using SNMP trap messages. A configuration file maps SNMP traps to Cisco MGM alarms. For more information, see the Cisco Element Management Framework User Guide. Before Cisco MGM can process alarm information, you need to register the traps you want the Cisco MGX 8260 Media Gateway to forward. You register traps using the Cisco WebViewer tool. You can also view MGX 8260 alarms and events directly from the Cisco WebViewer.

Performance Management

The Cisco MGX 8260 Media Gateway reports performance information for DS1, E1, DS3, and SONET lines. In addition, you can set performance thresholds and assign alarm severities that the nodes report. You view this information using the Cisco WebViewer tool. For more information, see the "Cisco WebViewer Sessions" section.

An optional product, the Cisco Voice CORBA Gateway, forwards Cisco MGX 8260 Media Gateway performance information to higher-level managers.

Monitoring Alarms and Events

You can monitor alarms and events from two screens:

• Map Viewer—Shows icons that indicate the most severe alarm

• Event browser—Shows a table of alarms and events

In addition, you can configure notification groups and channels. These notifications provide audible and visual alerts when significant events occur. For usage details, refer to the Cisco Element Management Framework User Guide; these sections are provided only as an orientation.

Map Viewer Display

For Cisco MGM, the Map Viewer displays information about the Cisco MGX 8260 nodes, cards, and other network equipment (see Figure 7-1).

• Object name

• Object class

• Object state

• Event unacknowledged count

• Event unacknowledged state

• Event outstanding state

---

Note   The icon displays the most severe event only.

---

• The icon for the object shows the following information

  • An event counter is displayed in the balloon

  • A number indicates the number of the most severe events in the category

  • A letter indicates the highest unacknowledged event severity in the category

  • A plus sign appears if there are other less severe, unacknowledged events in the category.

• The object has a colored outline which shows the event status color.

When the event status of an object changes in the network, the graphical cues change to reflect the new status.

Event Browser Display

The event status of objects contained in a map can affect the event status of the parent icon. In other words, if the event status changes on a map object, this is propagated to the parent icon. The event status is changed to reflect the most severe event of its children.

In Cisco EMF, when a condition (fault) occurs on a managed object, the system is notified immediately. This notification is shown as an event and can be viewed with the Cisco EMF Event Browser. The Event Browser is opened from the Cisco EMF Launchpad. A window similar to Figure 6-3 is displayed.

The Event Browser provides a tool to manage the network efficiently; you can list, query, and sort all or some events according to how you want to manage the network. Services can be invoked on events so faults can be attended to from the window that shows the event.

---

Note   You can also view events on Cisco EMF maps; however, only the most severe fault on a managed object is shown on the map icon.

---

The main panel in the Event Browser window displays a list of events including:

• Object name (the managed resource name)

• Time the event was raised

• Severity of the event (color-coded), refer to the "Alarm Severity Colors and Codes" section

• Description of the event

Two indicators, color coded to the severity of the event, are available to the left of the object name:

• Clear (an indicator to show if an event is active or cleared)

• Ack (an indicator to show if an event is acknowledged or unacknowledged).

Click the Ack button to indicate to other users that the fault is being worked on. The button changes to the color of the severity. If for any reason you cannot clear the problem, this button can be deselected so the event can be reassigned. The Clear button is highlighted when the fault has been rectified to indicate that the event requires no further attention.

Launching the Event Browser

You launch the Event Browser application using an icon on the Cisco EMF Launchpad.

This icon opens the Query Editor window, from which you can specify the type of
events to view.

Alternatively, you can right click on one or more objects in the Map Viewer and then select the Event Browser. The Event Browser displays only the events associated with the selected objects.

Viewing Cisco MGM Logs

You can check the log files for significant Cisco MGM and Cisco EMF events. The following table summarizes the important logs:

Registering Cisco MGX 8260 Traps

Cisco MGX 8260 Media Gateway nodes notify Cisco MGM of alarms and events using trap messages. Before Cisco EMF can display alarms, you must register traps at each MGX 8260 node.

When working with traps, you configure the following parameters:

• Manager address—The IP address of the Cisco MGM manager to receive traps

• Community string—The SNMP community strings for read and read-write access

• Trap registrations—The specific conditions to report and their severity

You register traps using the Cisco WebViewer. The following table summarizes the Cisco WebViewer procedures for trap registration and community string configuration. for more information, see the "Cisco MGM Community String Configuration" section.

The Cisco MGX 8260 Media Gateway supports the following trap categories:

Monitoring Alarms from the Cisco WebViewer

The Cisco MGX 8260 Media Gateway notifies maintenance or operations personnel about equipment alarms at several levels:

• Shelf

• Card

• Line

You can view the event log for notices about changes in the system. For example, inserting a new card adds an event to the log.

The WebViewer displays the most severe alarm in the upper right corner of every screen (see Figure 6-4).

Monitoring Performance from the Cisco WebViewer

The Cisco MGX 8260 Media Gateway reports performance statistics for the following lines:

• DS1 performance, real-time and interval statistics

• E1 performance, real-time, and interval statistics

• DS3 performance, real-time and interval statistics

• SONET performance, real-time and interval statistics for section, path, and line segments

The following table summarizes the Cisco WebViewer support for monitoring performance.
