The Alert Profile Management option lets you create new alert profiles and manage existing ones (Modify or Delete). The Alert Profiles page lists all existing alert profiles, along with the number of alerts generated for each profile. The application comes loaded with a preconfigured alert that can trigger an email alert when a link goes down or when there are no flows for more than 15 minutes.
The various columns displayed in the Alert Profiles page are described in the table below:
Column | Description |
---|---|
Name | The name of the alert profile when it was created. Click on the alert profile's name to see more information about the alert profile. |
Description |
Descriptive information entered for this alert profile to help other operators understand why it was created. |
Category |
The category defines, to what type of alert an alert profile belongs to. The pre-loaded and pre-configured "Link Down" alert belongs to the "Link Status" category. All other alerts created by the user fall under the "Utilization"category. |
Status (Enabled/Disabled) | This lists whether an alert profile is currently
enabled or disabled. Click the ![]() ![]() |
Last Hour Alerts | Lists the number of alerts generated for this alert profile in the last one hour. Colors are used to represent the number of alerts generated with each severity level. Red - Critical, Orange - Major, Yellow - Warning, and White - All. Click on each color to see the list of alerts generated with that severity. |
All Alerts | Lists the total number of alerts generated for this alert profile. Colors are used to represent the number of alerts generated with each severity level. Red - Critical, Orange - Major, Yellow - Warning, and White - All. Click on each color to see the list of alerts generated with that severity. |
Clear | Click the icon to clear all alerts generated for this alert profile |
The Alerts List is displayed when you click on any color against an alert profile in the Alert Profiles page, or from any link in the Generated Alerts box on the left pane. The list shows the alerts that were generated with the respective severity, along with the device that generated the alert, the time the alert was generated, and an option to view more details about the alert.
Click the Details link in the View column against an alert to view detailed information about the alert. The pop-up that opens up, shows the traffic graph outlining traffic values ten minutes before and after the alert was generated, along with details on top applications, sources, destinations, and conversations recorded during that time interval.
This is a preconfigured alert to send an email when the link goes down or when there are no flows for more than 15 minutes. By default this profile is disabled. This is similar to other alerts that are manually configured except that it can't be deleted. It is possible to have emails sent by this alert whenever no flows are received for over 15 minutes. It becomes activated only after the mail server settings are configured.
You can create new alert profiles, modify, or delete existing ones from the Alert Profiles page.

Remember to set the active timeout value
on the router to 1 minute so that alerts are
generated correctly. Refer the Cisco

section for more information on router settings. |
The steps to create an Alert Profile are:
The new alert profile is created and activated. The system
watches the utilization and raises alarms when the specified conditions
are met.

Only one alert is generated for a specified time duration. For example, say for a particular interface, the threshold is set as 60% and number of times is set as 3 times and the time duration is set as 30 minutes. Now lets assume that the utilization in that interface goes above 60% and stays above it. Then in 3 minutes, the above conditions will be met and an alert will be generated. The next alert will NOT be generated after 6 minutes, but only in the 33rd minute, if the condition persists. Thus for the specified 30 minutes time duration, only one alarm is generated. This is designed to avoid a lot of repetitive mail traffic. |
Select an alert profile, and click on Modify to modify its settings. You can change all of the alert profile's settings except the profile name. However, it is possible to modify the "Link Down" alert profile's name. There is also an option to clear details of all alerts created for this profile from this page itself. Once you are done, click Save to save your changes.
