Dtcprtt_example.txt1 Demonstrations of tcprtt, the Linux eBPF/bcc version.
23 During wrk testing, run tcprtt:
24 # ./tcprtt -i 1 -d 10 -m
38 The wrk output shows that the latency of web service is not stable, and tcprtt
45 # ./tcprtt -i 1 -d 10 -m -a 192.168.122.200 -A 192.168.122.100 -P 80
49 For example, run tcprtt on a storage node to show initiators' rtt histogram:
50 # ./tcprtt -i 1 --lport 3260 --byraddr -e
122 # ./tcprtt -i 1 -e
144 # ./tcprtt -h
145 usage: tcprtt [-h] [-i INTERVAL] [-d DURATION] [-T] [-m] [-p LPORT]

Dtcprtt.py4 # tcprtt Summarize TCP RTT as a histogram. For Linux, uses BCC, eBPF.
6 # USAGE: tcprtt [-h] [-T] [-D] [-m] [-i INTERVAL] [-d DURATION]
25 ./tcprtt # summarize TCP RTT
26 ./tcprtt -i 1 -d 10 # print 1 second summaries, 10 times
27 ./tcprtt -m -T # summarize in millisecond, and timestamps
28 ./tcprtt -p # filter for local port
29 ./tcprtt -P # filter for remote port
30 ./tcprtt -a # filter for local address
31 ./tcprtt -A # filter for remote address
32 ./tcprtt -b # show sockets histogram by local address
