Many organizations are concerned about volume of traffic in their network and NetFlow Analyzer makes it simpler to keep an eye on traffic volume. You could set up email alerts if the traffic goes beyond a particular level.
Here is a scenario to help you understand this feature better.
3 user groups use the same link in the router to connect to the external network(as mentioned in the link given below). The Administrator wants needs an alert when the downloads exceed a threshold value. NetFlow Analyzer helps in set these thresholds & set-up email alerts in case of any violation.
Solution:
In NetFlow Analyzer version 9.1 build 9100, we can create alerts based on Volume, Speed, Utilization and Packets. In this scenario, the following steps would help the Administrator, a great deal:
1. Create IP Groups
2. Configuring Mail Server Setting
3. Create Alert profile
1. Create IP group
As the groups are using the same interface, we cannot create alert based on interface. Each group operates within a specific range of IPs and we could to create IP Groups based on the range of IP addresses. You can create IP Groups by clicking:
Admin -> IP groups -> Add
Refer the screenshot:
2. Configuring Mail Server Setting
The Mail server setting should be configured to send out the email from NetFlow Anlayzer to the users. To check the setting, navigate to Admin -> Product Settings -> Mail/Proxy Server Settings and make sure the server settings are set and you are able to receive the test mail without any issue.
3. Create Alert profile
As we have created the IP Groups and verified the mail server setting, now we can trigger the alerts. Click Admin -> Alert profile -> Add, Refer:
You can name the alert and select IP Group and select IN Traffic for Download threshold (For IP Groups we can either set download or upload threshold combined threshold set is not available for IP groups).
Once the Alert is been set you will get an email if the selected IP group exceed given threshold limit.
If you are using volume based billing you can set the volume based alert in the Bill Plan itself. Know more about billing here.
