UNIX prstat vs top

While digging for problems in UNIX prstat comes handy in looking at the some of the statistics of the server.

prstat - report active process statistics

example:

Now
statistics are sorted by cpu high -low
prstat -s cpu
or -u for a particular user
prstat -u oracle -s cpu

or top 5 cpu events
prstat -s cpu -n 5

or
prstat -T (total)

Other options available to prstat are:

  -a    Report information about processes and users

-T Report information about processes and tasks.

  -u    Report only processes whose effective user  ID

  -v    Report  verbose  process  usage

  -s key            Sort output lines (that is, processes, lwps, or users)            by  key  in descending order. Only one key can be used            as an argument.             There are five possible key values:             cpu   Sort by process CPU usage. This is the default.             pri   Sort by process priority.             rss   Sort by resident set size.             size  Sort by size of process image.
-n ntop[,nbottom] (comes with ntop or nbottom)
