Don't take this the wrong way - porting nx.se as a standalone tool is a good idea... :) Tim and I have been maintaining nicstat for a number of years which serves a similar purpose (I created the Perl version of nicstat for the exact same reason - it was easier to toe around than the SE Toolkit). nicstat runs on both Solaris and Linux: http://blogs.sun.com/timc/entry/nicstat_the_solaris_network_monitoring # nicstat 5 Time Int rKB/s wKB/s rPk/s wPk/s rAvs wAvs %Util Sat 17:05:17 lo0 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 17:05:17 e1000g0 0.61 4.07 4.95 6.63 126.2 628.0 0.04 0.00 17:05:17 e1000g1 225.7 176.2 905.0 922.5 255.4 195.6 0.33 0.00 [...] The idea was to provide the most concise and generic view of these metrics. nx.se's output may be ideal as a verbose option that may contain OS specific metrics. I've also asked that nicstat be included in Solaris - either as an option to netstat, dladm or standalone. Including either nicstat or an nx.se port would be extreamly valuable. I think it makes sense for us to discuss this here on perf-discuss, and see if we can agree what to do. This will including deciding if it should be a netstat option, dladm, or stand alone. In the years that have passed, I think the default output of nicstat can be improved to have these fields: Time Int rKB/s wKB/s rPk/s wPk/s %Util Sat Err ie, drop the average size fields and add an error summary. I'd like see utilization, saturation and errors provided as standard metrics for all resources. Break downs are necessary too, to understand what they mean.
