procinfo (8)


       procinfo - display system status gathered from /proc


       procinfo [ -fsmadiDSbrChv ] [ -nN ] [ -Ffile ]


       procinfo  gathers  some system data from the /proc directory and prints
       it nicely formatted on the standard output device.

       The meanings of the fields are as follows:

              See the man page for free(1)  (preferably  the  proc-version  of
              free  (If  you  weren't around during the Linux 1.x days, that's
              the only version of free you'll have)).

              The time the system was booted.

       Load average:
              The average number of jobs running, followed by  the  number  of
              runnable  processes  and  the total number of processes (if your
              kernel is recent enough), followed by the PID of the  last  pro-
              cess run (idem).

       user:  The amount of time spent running jobs in user space.

       nice:  The amount of time spent running niced jobs in user space.

              The  amount  of  time  spent running in kernel space.  Note: the
              time spent servicing interrupts is not  counted  by  the  kernel
              (and nothing that procinfo can do about it).

       idle:  The amount of time spent doing nothing.

              The time that the system has been up. The above four should more
              or less add up to this one.

       page in:
              The number of disk block paged into core from disk. (A block  is
              almost always 1 kilobyte).

       swap out:
              The number of memory pages paged out to swapspace.

              The total number of context switches since bootup.

       disk 1-4:
              The  number  of  times  your hard disks have been accessed. This
              won't work for 1.0.x/1.1.x kernels unless you have  applied  the
              diskstat  patch  available  elsewhere  to your kernel, and might
              give surprising results if all your hard disks are of  the  same
              type (e.g. all IDE, all SCSI). [I'm not sure to what extend this
              is still true with recent kernels, but I don't have a mixed sys-
              tem so I can't check.]

              This  is either a single number for all IRQ channels together if
              your kernel is older than version 1.0.5, or two rows of  numbers
              for  each  IRQ  channel  if  your  kernel is at version 1.0.5 or
              later. On Intel architecture there  are  sixteen  different  IRQ
              channels, and their default meanings are as follows:

              0      Timer channel 0
              1      Keyboard
              2      Cascade for controller 2 (which controls IRQ 8-15)
              3      Serial Port 2
              4      Serial Port 1
              5      Parallel Port 2
              6      Floppy Diskette Controller
              7      Parallel Port 1
              8      Real-time Clock
              9      Redirected to IRQ2
              10     --
              11     --
              12     --
              13     Math Coprocessor
              14     Hard Disk Controller
              15     --

              Note  that  the meanings of the IRQ channels for parallel ports,
              serial ports and those left empty may have been changed  depend-
              ing  on your hardware setup. If that's the case on your machine,
              you're probably aware of it. If you're not, upgrade to at  least
              Linux 1.1.43 and let procinfo enlighten you about who uses what.

              The modules (loadable device drivers) installed on your machine,
              with their sizes in kilobytes. (Only with -m or -a option). Mod-
              ules with a use count larger than 0 are marked with an asterisk.

       Character and Block Devices:
              All available devices with their major numbers. (Only with -m or

       -nN    Pause N second between updates. This option implies -f.  It  may
              contain  a decimal point.  The default is 5 seconds. When run by
              root with a pause of 0 seconds, the  program  will  run  at  the
              highest possible priority level.

       -m     Show  info  about  modules and device drivers instead of CPU and
              memory stats.

       -a     Show all information that procinfo knows how to find.

       -d     For memory, CPU  times,  paging,  swapping,  disk,  context  and
              interrupt  stats,  display values per second rather than totals.
              This option implies -f.

       -D     Same as -d, except that memory stats are displayed as totals.

       -S     When running with -d or -D, always show values per second,  even
              when running with -n N with N greater than one second.

       -Ffile Redirect  output  to file (usually a tty). Nice if, for example,
              you want to run procinfo permanently on a virtual console or  on
              a terminal, by starting it from init(8) with a line like:

              p8:23:respawn:/usr/bin/procinfo -biDn1 -F/dev/tty8

       -b     If  your  kernel  is  recent enough to display separate read and
              write numbers for disk I/O, the -b flag makes  procinfo  display
              numbers  of  blocks rather that numbers of I/O requests (neither
              of which is, alas, reliably translatable into kilobytes).

       -i     Normally the IRQ portion of the display is squeezed to only dis-
              play non-zero IRQ channels. With this option you'll get the full
              list, but on Alphas and on Intel boxen with 2.1.104  kernels  or
              later procinfo won't fit inside a 80x24 screen anymore. Price of
              progress, I suppose.

       -r     This option adds an extra line to the memory info showing 'real'
              free memory, just as free(1) does.

       -h     Print a brief help message.

       -v     Print version info.


       When  running  procinfo  fullscreen,  you  can  change its behaviour by
       pressing n, d, D, S, i, m, a, r and b, which have the  same  effect  as
       the  corresponding  command  line options.  In addition you can press q
       which quits the program; s which switches back to the main screen after
       pressing  m  or  a;  t  which  switches back to displaying totals after
       pressing d or D; <space> which freezes  the  screen  untill  you  press
       another  key  again;  C  and  R which sets and releases a checkpoint in
       totals mode; and finally Ctrl-L which refreshes the screen.
