Brendan,
I hope you get nicstat as well as your entire toolkit included in the
OS distribution. Netstat alone does not cut it.
As for NX it is my goal to have a lightweight tool that pretty much
gathers most things related to the network that I might be interested
in.
nx gives me tcp and udp as well as NIC related statistics.
right now I get:
14:43:51 Iseg/s Oseg/s InKB/s OuKB/s Rst/s Atf/s Ret% Icn/s Ocn/s
tcp 0.0 0.0 0.00 0.00 0.00 0.00 0.0 0.00 0.00
IDGS/s ODGS/s IERR/s
udp 0.0 0.0 0.00
14:43:51 Ipkt/s Opkt/s InKB/s OuKB/s IErr/s OErr/s Coll% NoCP/s Defr/s
lo0 0.0 0.0 0.00 0.00 0.000 0.000 0.0 0.00 0.00
e1000g0 0.0 0.0 0.00 0.00 0.000 0.000 0.0 0.00 0.00
I plan to add listendrops in the next incantation.
On my box
nicstat gives me
arwen:nicstat 1 1
Time Int rKb/s wKb/s rPk/s wPk/s rAvs wAvs %Util Sat
14:45:24 e1000g0 0.52 0.17 0.65 0.51 819.31 331.07 0.01 0.00
14:45:24 mac 0.52 0.17 0.65 0.51 819.31 331.07 0.01 0.00
all good stuff but I want the nocanputs in particular.
Now in all honesty, I am only interested in Solaris, I work in
Sol 10 adoption.
So if we can come up with one lightweight tool to do it all then I will
re-write my post processors and support it whole heartedly.
