Filter

filter processes (default mode)

• GetConnections.ConnectionInfo.LocalPort=9091 or Name=java

filter connections (you should check the Connes and uncheck the Process)

• ConnectionInfo.LocalPort = 2181 or ConnectionInfo.LocalPort = 9091

filter both (you should check the both)

Note: filter processes and connections at the same time it's only meaningful that you filter processes based on connection and you want see connections only satisfies the filter for process. so we just use or to concat two (or more) filter, but we know that one is for process and another is for connection.

• GetConnections.ConnectionInfo.LocalPort = 2181 or ConnectionInfo.LocalPort = 2181

filter function implement based on uni-filter, see more document here
