Create Alert Definitions

Before You Begin

Read the Alerts Overview topic.
Review the Alert Definitions main page for an understanding of your current data set. See Alert Definitions Main Page Fields for field descriptions.

Use the Alert Definitions page to generate alerts that warn you of problems in your monitored environment. An alert definition consists of data criteria for triggering an alert. An alert is triggered when the event threshold exceeds the data criteria that is defined.

You can create an alert definition to monitor your data in real time. You can identify issues and attacks before they impact your network.

For example, if you are an administrator, you can define a condition such that if the number of firewall deny events crosses a predefined threshold in a given time frame for a specific device, you receive an email alert.

To create an alert definition:

Select Monitor > Alert > Alert Definitions.
Click the + icon.
Complete the configuration according to the guidelines provided in Table 1.
Click Ok.

A new alert definition with the configured alert triggering condition is created. You can view the generated alerts from the alert definition to troubleshoot the issues with your system.
