15.3.2.1 Modify a Statistic

To modify a Statistic, in the Configured Collection table, select a Statistic, and then select Edit -> Modify Statistic. In the

editable fields of the Polled Data Details form, make the appropriate changes (refer to 15.3.2), and then click Modify. The

changes are made immediately.

green.

To delete a statistic in the Configured Collection table, select a Statistic, and then select Edit -> Remove Statistic. A

confirmation dialog box will appear. Once the Yes option is clicked in the confirmation dialog, the Statistic is deleted from

the database.

1. In the Configured Collection panel, select the device on which you want to add the statistic.

2. Select Edit -> Add Statistic from the menu. The form shown in Figure 15-4 will appear.

3. Enter a name for the statistic in the Name field.

4. Enter the OID for the value to be polled in the OID field.

5. Uncheck the Active checkbox if you do not want this statistic to be active at this point.

6. Check the Advanced checkbox, then set the threshold values as needed.

7. Click Next.

8. If not already checked, check the Advanced checkbox, and then change the values as needed.

9. Click Add. Your new statistic will appear in the Configured Collection panel. If Active was checked, it will be enabled

(green).

15.4 Threshold Notification

Performance monitoring involves two concepts:

• Data is collected from agents of network devices and stored.

• The collected data is cross-checked with threshold values. If it exceeds the limits of threshold values, a notification can be

sent to the user indicating that network performance is degrading.

A threshold has the following:

• Value

Log Directly Checking means to store the collected data in flat files rather than storing them in database.

Default value: false (unchecked).

Log File The log file name with a full path (the location on the hard disk as where the log file has to be stored).

parentObj Name of the Managed Object which acts as the parent for this Data Identifier.

Poll ID A unique number associated with each Statistic to identify the Statistic. Poll ID is automatically

generated so no two Statistics will have the same Poll ID.

Advanced Allows the optional values to be modified.
