Monitoring Setup and Configuration

All the work thus far has involved building the foundation for this next section, configuring the NAM for

monitoring. Monitoring refers to all the functions that the NAM includes to provide you with more visibility into

your network. Monitoring refers not only to the passive process of collecting data for review and analysis but

also to the proactive process of creating alarms to notify you when an event occurs on your network that you

want to know about. Monitoring configuration consists of several steps:

1. Configuring data sources: For the NAM-1/2 includes configuring the switch to mirror data from

ports, VLANs, or the Cisco EtherChannel

tunnel to the NAM data port (SPAN/VACL); or for the NM-

NAM configuring CEF on interfaces to forward packets to the internal NAM port; also for both types of

NAMs configuring NetFlow devices to send flow statistics to the NAM. This step provides the data

streams for analysis and reporting

2. Configuring monitoring parameters: Instructing the NAM on what data (statistics, hosts,

conversations, application response time, DiffServ, VoIP) to collect from the configured data sources

and how it should be analyzed and reported

3. Configuring alarms: Configuring thresholds and alarms based on the data sources you configured in

Step 1

4. Configuring traps: Configuring the NAM to send traps to a management station for proactive

notification of events that occur

5. Preferences: Configuring the presentation of data and reports that you view under Monitor

The following section walks you through each of these steps, to lay the foundation for both passively and

proactively monitoring your network. This section shows you both the menus that you will use to configure the

NAM as well as sample reports that show you what effect your configuration choices have on the

presentation of data.
