No traffic at monitoring point

Problem

The application has registered an event whose description contains the following text: No traffic at monitoring point. The event description includes the duration of the absence of traffic, the name of the monitoring point, and the network interface that is not receiving traffic.

Solution

For traffic to arrive at the monitoring point, the following conditions must be met:

• The monitoring point is enabled and its current state is OK.
• On the network interface of the monitoring point, the network cable is connected to the Ethernet port.
• The rate of incoming traffic is more than 0 bps at the network interface of the monitoring point.

You can view information about monitoring points and network interfaces when connected to the Server through the web interface in the Settings section on the Deployment tab.

If the displayed rate of incoming traffic is 0 bps at the network interface of the monitoring point, verify that the following conditions are met:

• The network interface of the monitoring point is correctly configured in the operating system.
• When the network interface is connected to the industrial network switch, transmission of mirrored traffic through the connection port (SPAN) must be correctly configured on the network switch.
