What are the available fields for checking TCP Errors / Events?

The TCP statistics can be displayed in tables by selecting the appropriate column theme. They can reveal dysfunctions or unusual events.

TCP errors

For every TCP conversation, the following fields are available:

• RD Server/Client
• Duplicate ACKs
• Number of SYNs
• Number of handshakes
• Number of session ends
• Number of FINs from the client
• Number of FINs from the server
• Number of RSTs from the client
• Number of RSTs from the server
• Number of timeouts

By sorting on the RD or duplicate ACK fields, one can quickly check the worst conversations in terms of TCP performance. Also, the number of reset packets is usually noteworthy. One can then jump to the IP summary page of either the client or the server (depending on who is at fault) to gather further data on this event.
