No, it uses the "netstat -s" output. Linux doesn't do byte-counts for
the TCP/IP statistics, only on the entire network interface. So the
"netstat0" graph is not valid on Linux.

In Hobbit 4.2, you will have an "ifstat" graph tracking the number of
bits passing through your network interface.

What does your "netstat -s" output look like ? I have a pattern matching
for this where Hobbit looks for a "datagrams received" and "datagrams
output" line.

AFAIK, these counters are not reported by HP-UX.
