APM Architecture

To monitor applications, APM must “see” a copy of network communication between users and the monitored application. This can be achieved, for example, by using a SPAN port, a mirror port, or by using a TAP device.

The APM installation package comes in two versions:

1. APM

2. APM Probe

APM can be installed on a Flowmon Collector or a Flowmon Probe and it includes the complete APM functionality, including an APM probe.

APM Probe is a separate package used when analysis of network traffic from a remote location is necessary. Information about the analyzed traffic is sent from the APM Probe to the central APM. The APM Probe does not have a web interface and it only works in conjunction with APM. Probes are configured centrally using the APM web interface. The APM Probe is installed identically to APM and it must subsequently be configured to forward data to the central APM. This configuration is described in detail in Chapter Probe configuration.
