- 8.2.0, 8.1.0, 8.0.0
- Round Trip Time (RTT)
- A measure of time it takes to send a packet and receive an ACK message from the target host. Increased RTT over time indicates limited network bandwidth.
- The number of useful bytes, delivered by the network, to a destination over time. Low goodput in ratio to overall throughput indicates network issues, such as increased retransmits.
- Delay States
- A traffic condition in which the TCP protocol limits packet flow to avoid network congestion. During periods of congestion, the TCP protocol applies a mitigation algorithm to manage traffic flow according to the root cause of congestion. For more information about the traffic conditions that prompts a delay state, see TCP Dimensions and Metrics.
- The average number of new and closed TCP connections. Monitoring your TCP connections can indicate the level of activity across your network.
- The volume of transmitted data over the network, including payload, and other required data based on the packet format. The outcome of these packets over time can indicate a number of network issues including: congestion, server performance/capacity limits, or an attack.
