Understanding Top output

[eileen1017]

I tried man top and the system says no manual entry for top.
I am not an OS person. I am trying to understand the TOP output

What does LWP, PRI, and NICE mean? Why does NICE has negative value? Is the negative value good or bad? Please advice. Thank you very much.

Hi Eileen, whilst it's possibly not exactly the same as Solaris top, this should give you some idea:

http://unixhelp.ed.ac.uk/CGI/man-cgi?top

HTH.

Hi you will probably find that TOP is not an Oracle (Solaris) default tool and you should probably look at "prstat" which is similar and just as useful.

However, you can find out what version of top is installed on your Solaris machine with

$ top -v

Or identify the package installed that provides top for you with one of the following;

$ pkginfo -l | grep top 

expect lots to sort through but probably at the beginning it will be SMCtop if so  ...

$ pkginfo -l SMCtop

Once you have the version (or package0 go Google for exact man pages for that version.

IHTH

Laurie.
