= Round-Trip Time

[role="_abstract"]
|
|
Analyze network flow latencies by using TCP Round-Trip Time (RTT) metrics, which use eBPF hookpoints to identify performance bottlenecks and troubleshoot TCP-related issues through dedicated panels in the Overview view.
|
|
|
|
You can use TCP smoothed Round-Trip Time (sRTT) to analyze network flow latencies. You can use RTT captured from the `fentry/tcp_rcv_established` eBPF hookpoint to read sRTT from the TCP socket to help with the following:
|
|
|
|
* Network Monitoring: Gain insights into TCP latencies, helping
|
|
network administrators identify unusual patterns, potential bottlenecks, or
|
|
performance issues.
|
|
* Troubleshooting: Debug TCP-related issues by tracking latency and identifying
|
|
misconfigurations.
|
|
|
|
By default, when RTT is enabled, you can see the following TCP RTT metrics represented in the *Overview*:
|
|
|
|
* Top X 90th percentile TCP Round Trip Time with overall
|
|
* Top X average TCP Round Trip Time with overall
|
|
* Bottom X minimum TCP Round Trip Time with overall
|
|
|
|
Other RTT panels can be added in *Manage panels*:
|
|
|
|
* Top X maximum TCP Round Trip Time with overall
|
|
* Top X 99th percentile TCP Round Trip Time with overall
|
