In case you haven't been paying attention, Linux is in a mad dash to copy everything that made Solaris 10 amazing when it launched in 2005. Everyone has recognized the power of Zones, ZFS and DTrace but licensing issues and the sheer effort required to implement the technologies has made it a long process.
A friend asked me how he could see the network utilization in Solaris. It seems like a fairly simple request but for some reason this is not a simple command line away.
Recently, I was asked to give some advice on an integration project involving some Solaris web servers . One of the sides requested to install the top command. Now I know and love top for Linux but using top on Solaris is a waste in my opinion. Solaris comes with the prstat command built in- why use something else? Of course he answered that top was standard for him and he was used to it but I felt obliged to convince him otherwise so I dug around and found some proof 🙂
