An arrow represents the connection between every two servers and/or the clients and shows the port number connecting them, the protocol, and the communication direction. For example, Port: 80, Protocol: HTTP.
An arrow is displayed for each port and each direction. The colour of the arrow indicates how recent the latest activity was, and you can refer to the Connection Color Legend. You can also see this key on the maps by clicking at the bottom and expanding the key.
Notes: The connection failure threshold is configurable via Settings > Global Parameters >Connection failures sensitivityfield.
The protocol names are presented according to IANA Service Name and Transport Protocol Port Number Registry.
