Unix Metrics

Hi, Does anyone know of any programs that can create Unix (Solaris) server metrics such as server uptime, services uptime, processor utilization by hour by day, memory utilization by hour by day, active users by hour by day, etc? Thanks!

I/O Stats Metrics

What do others use for measuring I/O statistics? I'd like something versatile, as in being able to watch (like iostat, but easier to trend), generate load (like iozone, but more realistic), and perform somewhat generalized benchmarks (like bonnie, but more current.) It would scale from a few...

COUNTPERL(1p)						User Contributed Perl Documentation					     COUNTPERL(1p)

NAME

       countperl - count lines, packages, subs and complexity of Perl files.

SYNOPSIS

       countperl FILE_OR_DIRECTORY [FILE_OR_DIRECTORY ....]

REQUIRED ARGUMENTS

       At least one file or directory path must be supplied.

EXIT STATUS

       Exits zero on success, non-zero on failure.

DESCRIPTION

       countperl uses Perl::Metrics::Simple to examines the named files and recursivesly searches named directories for Perl files.

       Perl files are identified by Perl::Metrics::Simple->is_perl_file. Basically if the file ends in ".pl", ".pm", or ".t" or has what appears
       to be a perl shebang line.

       countperl produces a report on STDOUT of counts of total lines, packages, subroutines/methods, the minimum, maximum, mean, standard
       deviation, and median size and mccabe_complexity (cyclomatic complexity) of subroutines and the 'main' portion of each file (everything not
       in a subroutine.)

   Output Format
       Line counts do not include comments nor pod.

       The current output format is human-readable text:

	   Perl files found:		    3

	   Counts
	   ------
	   total code lines:	   856
	   lines of non-sub code:  450
	   packages found:	     3
	   subs/methods:	    42

	   Subroutine/Method Size
	   ----------------------
	   min: 		 3 lines
	   max: 		 32 lines
	   mean:		 9.67 lines
	   std. deviation:	 7.03
	   median:		 7.50

	   McCabe Complexity
	   -----------------
	   Code not in any subroutine::
	   min: 		 1
	   max			 1
	   mean:		 1.00
	   std. deviation:	 0.00
	   median:		 1.00

	   Subroutines/Methods:
	   min: 		 1
	   max: 		 5
	   avg: 		 1.00
	   std. deviation:	 1.36
	   median:		 1.00

	   Tab-delimited list of subroutines, with most complex at top
