Im used to this great tool called nmon. if you havnt heard of it you should check it out

Anyway im dabbeling with freebsd, and wanted to see if i can get it compiles. I managed to get the includes working, more or less atleast. and it compiles.

But it segfaults when i run it.

So has anyone run compiled it under freebsd or anyone have a good alternative?

madmaze, did you achieve it on any bsd like os ? – m1k3y02 Apr 26 '12 at 15:48

This tool won't work on FreeBSD since it relies on Linux's /proc filesystem to gather information. FreeBSD's /proc filesystem is totally different.

As an alternative, have a look at the built-in systat program.

Apparently, BSD systat does not differentiate read and write disk throughput, like nmon does, but otherwise it works just fine. – plang Apr 16 '14 at 13:55

Try these:

systat -vmstat 1 # BSD summary of system statistics (1 s intervals)
systat -tcp 1 # BSD tcp connections (try also -ip)
systat -netstat 1 # BSD active network connections
systat -ifstat 1 # BSD network traffic through active interfaces
systat -iostat 1 # BSD CPU and and disk throughput
