8.3 CUSTOMIZING EXISTING DATA COLLECTIONS

NNM provides many predefined collections that may be customized for your enterprise. By default, none of the collections are active. In order to activate them, copy and modify the collection. The example used in this section is the interface utilization collection,

If%util . The

If%util collection uses a MIB expression to calculate the available bandwidth of an interface, as described previously in this chapter.

The MIB collection can be customized by copying it. First, select the

If%util MIB Object from the upper part of the

Data Collection & Thresholds dialog box. Then, select the existing collection from the lower section of the Data Collection & Thresholds dialog box and select

EditCopyMIB Collection , as shown in Figure 8-22.

When you copy the collection, you see the data collection dialog box shown in Figure 8-23. Provide the

Source (hostname or IP address) for the collection and click

[Add] . Supply a

Polling Interval of 3 seconds (3s). Specify the

Threshold and

Rearm values. If you wish to store and view the data in order to more accurately set these values, set the

Collection Mode to

Store, No Thresholds . Use the default

Threshold Event Number (58720263). This event generates a message in the

Threshold Alarm category. To customize an event for the threshold and rearm values, specify a unique event number and click

[Configure Threshold Event…] and

[Configure Rearm Event…] , as described previously. Then, click

[OK] from the dialog box in Figure 8-23. Select

FileSave from the Data Collection & Thresholds dialog box shown in Figure 8-24. Resume the collection (

ActionsResume Collection ) and save it (

FileSave ).

The

snmpwalk command may be used to generate interface traffic when testing this data collection. This should allow the threshold value to be exceeded and a popup notification should be generated.
