Demonstrations of gethostlatency, the Linux eBPF/bcc version.

This traces host name lookup calls (getaddrinfo(), gethostbyname(), and
gethostbyname2()), and shows the PID and command performing the lookup, the
latency (duration) of the call in milliseconds, and the host string:

# ./gethostlatency
TIME      PID    COMM          LATms HOST
06:10:24  28011  wget          90.00 www.iovisor.org
06:10:28  28127  wget           0.00 www.iovisor.org
06:10:41  28404  wget           9.00 www.netflix.com
06:10:48  28544  curl          35.00 www.netflix.com.au
06:11:10  29054  curl          31.00 www.plumgrid.com
06:11:16  29195  curl           3.00 www.facebook.com
06:11:25  29404  curl          72.00 foo
06:11:28  29475  curl           1.00 foo

In this example, the first call to lookup "www.iovisor.org" took 90 ms, and
the second took 0 ms (cached). The slowest call in this example was to "foo",
which was an unsuccessful lookup.

USAGE message:

# ./gethostlatency -h
usage: gethostlatency [-h] [-p PID]

Show latency for getaddrinfo/gethostbyname[2] calls

optional arguments:
  -h, --help         show this help message and exit
  -p PID, --pid PID  trace this PID only

examples:
    ./gethostlatency           # time getaddrinfo/gethostbyname[2] calls
    ./gethostlatency -p 181    # only trace PID 181
