| Enabled by default? | No |
None
| Name | Description | Type | Labels |
|---|---|---|---|
windows_tcp_connection_failures |
Number of times TCP connections have made a direct transition to the CLOSED state from the SYN-SENT state or the SYN-RCVD state, plus the number of times TCP connections have made a direct transition from the SYN-RCVD state to the LISTEN state | counter | af |
windows_tcp_connections_active |
Number of times TCP connections have made a direct transition from the CLOSED state to the SYN-SENT state. | counter | af |
windows_tcp_connections_established |
Number of TCP connections for which the current state is either ESTABLISHED or CLOSE-WAIT. | gauge | af |
windows_tcp_connections_passive |
Number of times TCP connections have made a direct transition from the LISTEN state to the SYN-RCVD state. | counter | af |
windows_tcp_connections_reset |
Number of times TCP connections have made a direct transition from the LISTEN state to the SYN-RCVD state. | counter | af |
windows_tcp_segments_total |
Total segments sent or received using the TCP protocol | counter | af |
windows_tcp_segments_received_total |
Total segments received, including those received in error. This count includes segments received on currently established connections | counter | af |
windows_tcp_segments_retransmitted_total |
Total segments retransmitted. That is, segments transmitted that contain one or more previously transmitted bytes | counter | af |
windows_tcp_segments_sent_total |
Total segments sent, including those on current connections, but excluding those containing only retransmitted bytes | counter | af |
