Threshold Based Alerts

Threshold Based Alerting on NetFlow

A network bandwidth monitoring tool does no good to a network administrator, if he has to sit all day long watching and waiting for the event to occur. And it is close to impossible to keep an eye on all the network activities 24x7. What you need is a monitoring system that will alert you when your network is not on the right track, so that you can rectify them before it adversely affects your business.

NetFlow Analyzer generates alerts and notifies you, when the traffic utilization exceeds pre-defined threshold settings. It also helps you to create and manage your thresholds effectively with the help of alert profiles. You can configure the alert threshold values based on utilization, duration and frequency.

Utilization: Set limits for bandwidth utilization by the IP groups and other device groups.

Duration: Set time periods and generate alerts based on threshold violations during that time period.

Frequency: Set the number of times the utilization is allowed to exceed alert threshold before an alert is raised.

Set alert profiles for IP groups, Interfaces and Interface groups and define alerts based on the IN traffic, OUT Traffic or on Both. The Network Administrator is also alerted when the link goes down or when there are no flows for more than 15 minutes.

Network administrators cannot afford to miss alerts generated. For this reason NetFlow Analyzer provides the SNMP traps as alert notification system. You can set up an SNMP Trap notification to immediately notify any application or SNMP device, when an alert is triggered. The bandwidth alerts generated by NetFlow Analyzer can also be forwarded as a trap message to any manager application. This in a way helps to consolidate all the network alerts in a single place in the manager application. For the convenience of network administrators, Alerts Profiles can be configured to send email notification to immediately notify, when the alert is triggered. The notifications can be sent along with a PDF attachments, to any number of email addresses specified.
