Getting Started


The following figure outlines the tasks you must complete in order to begin using the EM.


Figure 2-1   Workflow for the EM


The EM runs in the background following installation. To begin using the EM through a custom graphical user interface (GUI), you must start a Cisco EMF user session. An EM session automatically starts when you start a Cisco EMF user session. Because the EM is accessible through the Cisco EMF Launchpad, it is important to understand how Cisco EMF works before you begin using the EM.


Note   For further details regarding Cisco EMF, see the Cisco Element Management Framework User Guide Release 3.2.

This chapter covers the following:

Starting a Cisco EMF User Session

In order to start a GUI-based Cisco EMF user session, Cisco EMF must be running and successfully initialized. Cisco EMF automatically initializes during the system boot-up process following installation. If (upon starting) you receive a message that Cisco EMF is not running, contact your system administrator.


Note   For additional information, see the Cisco Element Management Framework Installation and Administration Guide Release 3.2.

When Cisco EMF is running, you can start a user session. Each active Cisco EMF session uses a single Cisco EMF user license.

To start a Cisco EMF user session, proceed as follows:


Step 1   From the command line on a terminal window, enter:

CEMF_ROOT/bin/cemf session

CEMF_ROOT is the Cisco EMF installation root directory (for example, /opt/cemf).

The Login window appears.


Figure 2-2   Login Window


Step 2   Enter your user name and password.

Step 3   Choose Ok to proceed.

When an unknown user name or password is entered, an error displays. Choose Ok, then enter a valid user name and password.

You have three attempts to enter a valid user name and password. After the third, failed attempt the session does not start and the Login window closes.

When a valid user name and the password are entered, the session starts and the Cisco EMF Launchpad appears (see the following figure). The EM automatically starts when you start a Cisco EMF user session.



Cisco EMF Launchpad

The icons which display in the Cisco EMF Manager and Event Manager panels on the Launchpad represent the applications the Cisco EMF installation provides. Additional icons may appear following some package installations. The following figure displays the Cisco EMF Launchpad and the icons which represent the standard Cisco EMF tools.

Note   For further information on the Cisco EMF Launchpad and the tools it provides, see the Cisco Element Management Framework User Guide Release 3.2.

Map Viewer (Viewer)

MapViewer allows complete flexibility in viewing, building, and monitoring your network using graphical representations of network elements.

MapViewer is the primary entry point into the EM functionality. When the MapViewer application launches, a window appears corresponding to the highlighted map icon in the hierarchy pane. You can easily monitor the status of all network elements or abstractions of elements within the network and you can launch any of the additional applications on the Cisco EMF Launchpad.

Groups

Object Group Manager allows you to organize network elements into object groups. An object group is a collection of objects which relate in some way to each other. They may all be the same type of equipment or all belong to the same customer.

Object groups can be built manually or by building a query. Some Cisco EMF subsystems may also build object groups which may be visible and usable by the Cisco EMF user.

Access

User Access Control allows system administrators the opportunity to control the features of their system that are accessible by the various levels of personnel. This is important for secure network management.

Event Browser (Events)

One of the most important aspects of Network Service Management is the ability to identify faults and other events on the network, and to take action to resolve them quickly and efficiently. For example, there may be a power supply fault in a chassis which would require an engineer's support to rectify the fault. This fault is critical to the running of the network and would need prompt attention.

In Cisco EMF, when a condition (fault) occurs on a managed object in the network, the system receives notification immediately. Notification is shown as an event and is viewable with the Cisco EMF Event Browser (when configured to do so).

Auto Discovery

Auto-Discovery allows you to examine the network for IP and SNMP devices, and create a chassis object for each new device which discovers. Auto-discovery opens from the Cisco EMF Launchpad window or from a pop up menu available on selected objects.

Notification Profiles

An important aspect of a monitoring system which captures and reacts to events on the network is when and how a network operator is informed of these events. The Cisco EMF Event Manager uses notification profiles to determine when and how the network operator is informed of events. For example, when the temperature of a line card rises 10 degrees above normal, an e-mail might be sent to the network operator warning of a potential problem; or a minor event might be generated if the temperature does not fall to within ten degrees of normal in twenty minutes depending on the notification profile established.

Notification profiles are collections of notifications. Each notification profile has a name and description and is accessible by all Event Manager users. Each includes a list of notifications, and is run following a trigger, which could be an event entering an event group or a threshold breach in a thresholding regime. For example, when the first event is received by an event group, a notification profile may be triggered which causes a sound to occur in order to alert the operator. As well as audible alerts, a notification could be set up to display on screen or to trigger an external notification such as an e-mail.

Thresholding Regimes

A Thresholding Regime is a set of threshold conditions for specified object attributes which, when breached, causes one or more notification profiles to be run. The Thresholding Regime defines which attributes should be polled and on what period, and defines the thresholding conditions. The Thresholding Regime specifies object groups which contain the objects whose attributes will be polled.

Event Groups

Event Groups allows you to organize network elements into event groups, and also view the status of these groups as scoreboards. Users can create, delete, and modify event groups and scoreboards. Event groups are available to all users.

Event groups can be any combination of objects derived from the Cisco EMF managed object class. These groups are set up using queries which can be configured to match your requirements. For example, you could choose to monitor a particular device, specify a time period, and choose to look at events which are warnings or critical. You define a query so that the event group only includes the events which meet the criteria you define. As soon as the group is created it starts monitoring against the criteria specified in the event query setup. Event groups created in the Event Groups application are persistent; they are not cleared when the application is closed.

The Event Groups application also enables you to view the events associated with an event group in a scoreboard format. This displays the overall status of the event group as a pie chart, with the associated severity color coding. A scoreboard also shows the total number of events which have entered the event group and the highest severity of the events in the group. An icon displays when a running notification has been set up for the event group.

Event Groups opens from the Cisco EMF Launchpad.

Pre Filtering

Filtering events at the point at which they enter the system is known as pre-filtering. When specified pre-filtering criteria is met, events are not available to the EMS. Filtering certain events prevents unnecessary data from being written to the database, improving overall system performance. The Pre Filtering application opens from the Cisco EMF Launchpad.

Event filtering is also available in the Event Browser and Event Group applications to determines which alarms display to a certain user or participate in a event group.

Quitting a Cisco EMF User Session

To quit the current Cisco EMF session, proceed as follows:


Step 1   Perform one of the following actions:

A confirmation window appears asking, Do you wish to quit the Cisco EMF Manager System?.

Step 2   Click Yes to quit the session (all active applications are closed and the session terminates), or No to return to the current Cisco EMF session.
