# tcplife Trace the lifespan of TCP sessions and summarize.
# For Linux, uses BCC, BPF. Embedded C.
#
# USAGE: tcplife [-h] [-C] [-S] [-p PID] [-4 | -6] [interval [count]]
#
# This uses the sock:inet_sock_set_state tracepoint if it exists (added to
# Linux 4.16, and replacing the earlier tcp:tcp_set_state), else it uses
# kernel dynamic tracing of tcp_set_state().
#
# While throughput counters are emitted, they are fetched in a low-overhead
# manner: reading members of the tcp_info struct on TCP close. ie, we do not
# trace send/receive.
