You can achieve the above scenario using the Anomaly Filters.
Steps:
- Filters section:
Give Source is 192.168.1.1
- Threshold section:
In a period of 1 Hour, If Total Traffic exceeds 100 MB, create an Alert with Priority as High Check for every 15Mins. Select the owner for the alert <Admin> from the Assign Owner for the Alert: combo box.
- Select Send E-Mail notification check box and select 5th occurrence. Provide valid email ids in the Mail To box.

Alert Profile Examples
With the combinational usage of Alert Profile Type, Filters, and Threshold parameters, you will be able to create Alert Profiles addressing your precise and selective needs. Some of the example profile are discussed below:
- Say, you want to get notification of all Critical Events, enter the criteria as Severity is '2". For the severity and severity number mapping refer the table given below.
- Same way, if you want to get notification of all attack logs, enter the criteria as RecordType is 'attack'.
- If you want to get notification for all virus logs, enter the criteria as RecordType is 'virus'.
