Problem

Ways to identify connections from/ to B2Bi and Integrator in the stats logs.

Resolution

If you want to actually check how many connections are opened from B2Bi to Integrator, an easy way to do that would be to create a script (use "netstat" for example) to output all CONNECTED sockets at a specific time that involve those two ports.

Using the stats, for connections to Integrator over one minute, you can diff two consecutive entries in the stats logs for "B2BiSendClient.send.timer.<node_name>: Count:"

For messages from Integrator to the TE node, you can look at the following lines in stats logs:
"Consumption.B2BiServer://localhost:6070 in exchange Global B2Bi Server Exchange Point.<node_name>.PerDay.<node_name>:"
"Consumption.B2BiServer://localhost:6070 in exchange Global B2Bi Server Exchange Point.<node_name>.PerHour.<node_name>:"
"Consumption.B2BiServer://localhost:6070 in exchange Global B2Bi Server Exchange Point.<node_name>.PerMinute.<node_name>:"
"Consumption.B2BiServer://localhost:6070 in exchange Global B2Bi Server Exchange Point.<node_name>.Total.<node_name>:"
