Probes

You must configure what APM network card can see the application traffic to be monitored.

You can Edit or Remove an existing probe using the links on the right. You can insert a new probe by clicking New probe. Also, you can activate a probe using the toggle in the Active column. Only Active probes monitor traffic on the defined network card and forward it for further processing.

The icon in the first column of the table can be green, red, or yellow. A green icon means that an application server is assigned to the probe and the probe is capturing network traffic. A red icon is displayed for inactive probes. A yellow icon appears when the probe cannot be started because no active server is assigned to it.

The following is a description of the window where the probe configuration is edited:

• Name – the name of the probe.

• Mode – Local = local probe on a Flowmon device / Remote = external probe.

• Active – activation/deactivation of the probe.

• TAP mode – activate if traffic is monitored by a TAP device. Two network cards are configured in this mode.

• Network card 1 – select the network card where you can see the network traffic of applications you want to monitor.

• Network card 2 – this displays only if the TAP mode is active.

Flowmon APM must “see” network traffic of applications (specifically, a copy of traffic) that are to be monitored. This can be achieved, for example, using a SPAN port/a mirror port on the active element (switch/router) or, for example, using a TAP device (Network TAP). In the case of the virtual environment, the promiscuous mode must be enabled for APM.

Statistical data can be displayed after clicking the green icon on an active probe. A description of abbreviations of the items is listed under the Probe statistical data heading in the Other chapter.
