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.
Configuring Alert Definitions
To create an alert definition:
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.
