    NAME

    xosview - X based system monitor
     
    

    SYNOPSIS

    xosview [options]

     

    DESCRIPTION

    xosview is a monitor which displays the status of several system based parameters. These include CPU usage, load average, memory usage, swap space usage, network usage, interrupts, and serial port status. Each of these is displayed as a horizontal bar which is separated into color coded regions. Each region represents a percentage of the resource which is being put to a particular use. Typing a 'q' in the window will terminate xosview.

    At the moment xosview runs on six platforms (Linux, NetBSD, FreeBSD, OpenBSD, some Solaris systems, and HPUX). Not all of the meters described below are supported on all platforms. Some of the meters may appear different depending upon the platform xosview is running on. Note that *BSD is used as an abbreviation for all three of the free BSD operating systems (NetBSD, FreeBSD, OpenBSD).

    OPTIONS

    Most of these command line options are just a convenient way to set one or more of xosview's resources. Please see the RESOURCES section for more details on what the resource is for.

    -v

    Displays the version number.

    -name name

    Sets the Resource name xosview will use (same as the -name option for typical X applications like xterm). When performing resource lookups, xosview will look under name, and then under ``xosview''. For an example, perform the following (as documented in README.netbsd):

      xrdb -merge Xdefaults.stipple
      xosview -name xosvstipple &
      xosview -name xosvstipplebw &

    -display display

    Sets the X display to display. This option overrides the xosview*display resource.

    -font font

    Specifies the font xosview will use for labels. This option overrides the xosview*font resource.

    -title title

    This option sets the name xosview will tell the window manager to use for the X window and icon. This option overrides the xosview*title resource.

    -geometry geometry_string

    Sets the X geometry to geometry_string. This option overrides the xosview*geometry resource.

    -captions

    This option overrides the xosview*captions resource. It is equivalent to setting xosview*captions to "False".

    +captions

    This option overrides the xosview*captions resource. It is equivalent to setting xosview*captions to "True".

    -labels

    This option overrides the xosview*labels resource. It is equivalent to setting xosview*labels to "False".

    +labels

    This option overrides the xosview*labels resource. It is equivalent to setting xosview*labels to "True".

    -usedlabels

    This option overrides the xosview*usedlabels resource. It is equivalent to setting xosview*usedlabels to "False".

    +usedlabels

    This option overrides the xosview*usedlabels resource. It is equivalent to setting xosview*usedlabels to "True".

    -cpu

    This option overrides the xosview*cpu resource. It is equivalent to setting xosview*cpu to "False".

    +cpu

    This option overrides the xosview*cpu resource. It is equivalent to setting xosview*cpu to "True".

    -load

    This option overrides the xosview*load resource. It is equivalent to setting xosview*load to "False".

    +load

    This option overrides the xosview*load resource. It is equivalent to setting xosview*load to "True".

    -mem

    This option overrides the xosview*mem resource. It is equivalent to setting xosview*mem to "False".

    +mem

    This option overrides the xosview*mem resource. It is equivalent to setting xosview*mem to "True".

    -swap

    This option overrides the xosview*swap resource. It is equivalent to setting xosview*swap to "False".

    +swap

    This option overrides the xosview*swap resource. It is equivalent to setting xosview*swap to "True".

    -battery

    This option overrides the xosview*battery resource. It is equivalent to setting xosview*battery to "False".

    +battery

    This option overrides the xosview*battery resource. It is equivalent to setting xosview*battery to "True".

    -net

    This option overrides the xosview*net resource. It is equivalent to setting xosview*net to "False".

    +net

    This option overrides the xosview*net resource. It is equivalent to setting xosview*net to "True".

    -network maxbandwidth -networkBW maxbandwidth -networkBandWidth maxbandwidth

    These options override the xosview*networkBandwidth resource. They cause xosview to display a meter that will shows network usage, with a maximum bandwidth of maxbandwidth. Notice that setting the bandwidth to 0 no longer disables the meter -- use the ``-net'' option instead.

    -page

    This option overrides the xosview*page resource. It is equivalent to setting xosview*page to "False".

    +page

    This option overrides the xosview*page resource. It is equivalent to setting xosview*page to "True".

    -pagespeed val

    This option overrides the xosview*pageBandWidth resource. The resource xosview*pageBandWidth will be set to val.

    -disk

    This option overrides the xosview*disk resource. It is equivalent to setting xosview*disk to "False".

    +disk

    This option overrides the xosview*disk resource. It is equivalent to setting xosview*disk to "True".

    -int

    This option overrides the xosview*int resource. It is equivalent to setting xosview*int to "False".

    +int

    This option overrides the xosview*int resource. It is equivalent to setting xosview*int to "True".

    +irqrate

    This option overrides the xosview*irqrate resource. It is equivalent to setting xosview*irqrate to "True".

    -intrate +intrate

    Equivalent to -irqrate and +irqrate.

    -xrm resource_string

    This switch allows any of xosview's resources to be set on the command line. An example of how the xosview*memFreeColor could be set using this option is shown below (Note the use of " to prevent the shell from expanding '*' or from creating two separate arguments, 'xosview*memfreeColor:' and 'purple'):
    -xrm "xosview*memFreeColor: purple"

     

    X RESOURCES

    The following is a list of X resources supported by xosview. Each has a default value assigned to it. These values can be found in the file Xdefaults which can be obtained in the source distribution of xosview. They can be overridden in the usual places (/usr/lib/X11/app-defaults/XOsview, $HOME/.Xdefaults, etc.).

    It should be noted that it is OK to have a resource defined for a port of xosview that does not support the feature the resource configures. Xosview will simply ignore the resources that are set for it but not supported on a given platform.

    General Resources

    xosview*title: name

    The string that xosview will use for the X window title. Normally xosview will use 'xosview@machine_name' for a title. This resource overrides the default behavior.

    xosview*geometry: geometry_string

    This is a standard X geometry string that defines the size and location of the X window used by xosview.

    xosview*display: name

    The name of the display where xosview will contact the X server for drawing its window.

    xosview*pixmapName: name

    The filename of an X pixmap (xpm) file for use as a background image.

    xosview*captions: (True or False)

    If True then xosview will display meter captions.

    xosview*labels: (True or False)

    If True then xosview will display meter labels.

    xosview*meterLabelColor: color

    The color to use for the meter labels.

    xosview*usedlabels: (True or False)

    If True then xosview will display labels that show the percentage of the resource (or absolute amount, depending on the meter) being used. This option requires that the labels option also be set to True.

    xosview*usedLabelColor: color

    The color to use for "used" labels.

    xosview*borderwidth: width

    The width of the border for the xosview window.

    xosview*font: font

    This is the font that xosview will use.

    xosview*background: color

    This is the color that will be used for the background.

    xosview*foreground: color

    This is the color that will be used for the foreground.

    xosview*enableStipple:  (True or False)

    Change to true to try stipple support. This is primarily for users stuck with 1-bit monitors/display cards. Try setting enableStipple true. Please give us feedback on this, if you use it. It needs some more work, but no one has given us any feedback so far.

    xosview*graphNumCols: number

    This defines the number of sample bars drawn when a meter is in scrolling graph mode. This also has the side-effect of defining the width of the graph columns. This is only used by meters which have graph mode enabled.

    Load Meter Resources

    xosview*load: (True or False)

    If True then xosview will display a load meter.

    xosview*loadWarnColor: color

    This is the color that the load meter will use once the load average is greater than 1.

    xosview*loadProcColor: color

    This is the color that the load meter will use to display the load average when it is less than or equal to 1.

    ..pp load

    xosview*loadAlarmThreshold: int .RS This number (which must be an integer >= 1) sets the value at which the loadmeter changes its status and color from "normal" to "alarm". The default value is 2. .RE

    xosview*loadDecay: (True or False) .RS You should probably leave this at the default value (False). The load is already a time-averaged value! .RE

    .dg load

    ..uf load

    CPU Meter Resources

    xosview*cpu: (True or False) .RS If True then xosview will display a cpu meter. On linux SMP machines this will cause a seperate meter to be displayed for each cpu if Jerome Forissier's kernel patch has been applied. See the 'README.linux' file for more details. .RE

    ..cc cpu User "cpu user time" .cc cpu Nice "cpu nice time" .cc cpu System "cpu system time" .cc cpu Interrupt "cpu interrupt time" .cc cpu Free "cpu idle time"

    ..pp cpu .dc cpu .dg cpu .uf cpu

    Memory Meter Resources

    ..xt mem

    ..cc mem Used "used memory" .cc mem Shared "shared memory" .cc mem Buffer "buffer memory" .cc mem Cache "cache memory" .cc mem Free "free memory" .cc mem Shared "shared memory" .cc mem Text "HP text memory" .cc mem Other "HP ``other'' memory" .cc mem Active "NetBSD active memory" .cc mem Inactive "NetBSD inactive memory"

    ..pp mem .dc mem .dg mem .uf mem

    Swap Meter Resources

    ..xt swap

    ..cc swap Used "used swap" .cc swap Free "free swap"

    ..pp swap .dc swap .dg swap .uf swap

    Page Swapping Meter Resources

    ..xt page

    xosview*pageBandWidth: maxEvents .RS This number is used to specify the expected maximum bandwidth (in events / sec) for the page meter. When the expected maximum bandwidth (maxEvents) is exceeded then the page meter will display the relative percentage of page swapping (25% in, 75% out). .RE

    ..cc page In page-in .cc page Out page-out .cc page Idle idle

    ..pp page .dc page .dg page .uf page

    Network Meter Resources

    xosview*net:    (True or False)
    .RS If True xosview will display the NetMeter. Linux users will have to configure their kernels and setup some ip accounting rules to make this work. See the file README.linux which comes with the xosview distribution for details. .RE

    xosview*netBandwidth: maxBytes .RS This number is used to specify the expected maximum bandwidth (in bytes / sec) for the meter. When the expected maximum bandwidth (maxBytes) is exceeded then the network meter will display the relative percentage of network usage (25% incomming, 75% outgoing). .RE

    ..cc net In incoming .cc net Out outgoing .

    xosview*netBackground: color .RS This is the color that the network meter will use for the "idle" field. .RE

    ..pp net .dc net .dg net .uf net

    Serial Meter Resources

    xosview*serial(0-9): (True, False, or portBase) .RS If True then xosview will display a serial meter for ttySx. The portbase will be autodetected. Because autodetection can fail, (if the port is locked by ppp/slip for example) you can specify the portbase instead of "True". If a portBase is used then xosview will use it instead of trying to autodetect.

    For this to work on Linux xosview needs to be suid root in order to have access to the ports. See the file README.linux which comes with the xosview distribution for more details. .RE

    xosview*serialOnColor: color .RS This is the color the serial meter will use for bits that are set. .RE

    xosview*serialOffColor: color .RS This is the color the serial meter will use for bits that are not set. .RE

    ..pp serial

    Interrupt Meter Resources

    xosview*interrupts: (True or False) .RS If True then xosview will display an interrupt meter. .RE

    xosview*intOnColor: color .RS This is the color that will be used to show "active" interrupts. .RE

    xosview*intOffColor: color .RS This is the color that will be used to show "inactive" interrupts. .RE

    ..pp int

    Battery Meter Resources

    xosview*battery: (True or False) .RS If True then xosview will display a battery meter. Linux users will need to have APM support in their kernels for this to work. See the file README.linux which comes with the xosview distribution for more details. .RE

    xosview*batteryLeftColor: color .RS This is the color that will be used to show the amount of battery power left. .RE

    xosview*batteryUsedColor: color .RS This is the color that will be used to show the amount of battery power used. .RE

    ..pp battery .uf battery

    Disk Meter Resources

    ..xt disk

    ..cc disk Used "bytes transferred (in or out)" .cc disk Idle idle

    xosview*diskBandwidth: bandwidth .RS This number is used to specify the expected maximum bandwidth in bytes per second for the disk meter. .RE

    xosview*diskWriteColor: color .RS This color will be used for the linux meter to show writes. .RE

    xosview*diskReadColor: color .RS This color will be used for the linux meter to show reads. .RE

    ..pp disk .dc disk .dg disk .uf disk

    .SH BUGS

    Here is a list of known bugs in xosview-1.6.2.a. Reports of unknown bugs are appreciated and should be directed to:

    .RS Mike Romberg ([email protected]) .RS General xosview bugs and bugs related to the Linux and HPUX ports. .RE .RE

    .RS Brian Grayson ([email protected]) .RS Bugs related to the NetBSD port. I am also a catch-all for bug reports for the other *BSDs and SunOS. .RE .RE

    Occasionally (and unrepeatably?), the NetBSD xosview will clobber the NET text in the netmeter with horizontal black bars and the used-label numbers. I'm guessing this has something to do with the net numbers reaching some unusual number (like 0 or maximum), but have not been able to pinpoint it further. BCG

    .SH OBTAINING

    The most current version of xosview can be found at the following sites:

    .RS ftp://sunsite.unc.edu/pub/Linux/system/status/xstatus http://lore.ece.utexas.edu/~bgrayson/xosview.html .RE

    For *BSD users with the ports/package system, the sysutils/xosview tree ought to also have a version that is just as up-to-date.
