Try this little hamster in Perl for a simple system overview (on Linux):

Groups processes by name, e.g. all the processes named "httpd" go into one line; or a special process is given its own line.

For each group give:

total CPU usage used (percent of single CPU, so the total can be over 100%)
total mem usage used (percent)
total 'rss', 'size', 'sz', 'vsz' used (from 'ps')
total number of processes grouped
total number of threads managed by the grouped processes
total number of file descriptors used by the processes grouped ("FILES")
total number of internet sockets used (that value is already included in "FILES")
total number of unix domain sockets used (that value is already included in "FILES")
