In case of any problem with a connection or a host being monitored, NetWatch can send a notification to the administrator. You can define several conditions when an alert event is generated and also several notification actions. netTools can also send a notification when a problematic situation ends - for example when a non responding host starts to respond.
To enable alarm, select Set alerts in the Pick a Task section on the side bar.
When is an alert generated?
There are 3 conditions when the alert is generated (event types):
In points 2 and 3 you define the "reset" threshold for the event. This is important - otherwise an alert would be generated every time the condition is met. That could cause the same alert to be repeated every minute. The measured value must fall below the reset threshold before the next alert is generated. Please take a look at the chart below.
The red line indicates the alert threshold. When the response time or packet loss rate rises above this threshold an alert will be generated. But for the next alert to be generated this value must fall below the reset threshold. This prevents repeated alerts for the same event.
Notification of event end
For every event type, you can turn on notification about its end. For "Packet loss rate too high" and "Response time too high" events, you define the reset threshold. When the value falls below this threshold, the program considers the event to be finished. For "Host not responding" events, the connection is restored when the host responds to at least one ping request.
When the event ends and you turn on the notification for this event, the program will generate an action for such event.
Actions
You can define actions which will be executed for every event. The following actions are available:
