Poking around the system, I discovered the "m" option to
netstat and got this:
261 mbufs in use
74/17088 mbuf clusters in use (current/max)
0/4/4528 sfbufs in use (current/peak/max)
213 KBytes allocated to network
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
935 calls to protocol drain routines
... which would be a lot more useful if I had a reference
standard. Which I can't seen to find.
This was taken on a system which has had minimal network
traffic for several hours. How would I expect things to change as
load increased? What are the warning signs the network is
approaching saturation?
