N3T_TCP_Flow_Controls

Flow Control is the sum of input window probes, input window updates, output window probes, and output window updates since TCP/IP initialization.

This situation occurs when the reading application is having trouble keeping up with the sending application. In most cases this is not a problem, but is instead normal behavior. TCP has built-in self-correcting logic to address this type of situation. When the receiving application cannot keep up, TCP on the receiving side alerts TCP on the sending side to slow down the amount of data being sent.

However, if a flow control issue is instead a side effect of an application problem such as the application being hung, look for additional alerts that might have been triggered, indicating an application issue.

This situation is informational.

Formula: CHANGE(Total_Flow_Controls) >= 1 over three consecutive data sampling intervals
