XOSVIEW(1)

NAME
xosview - X based system monitor

SYNOPSIS
xosview [options]

DESCRIPTION
xosview is a monitor which displays the status of several system parameters. These include CPU usage, load average, memory, swap space, network usage and more. Each resource is displayed as a horizontal bar which is separated into color coded regions showing how much of the resource is being put to a particular use.

xosview runs on several platforms (Linux, NetBSD, FreeBSD, OpenBSD, DragonflyBSD, some Solaris systems, IRIX 6.5, HPUX and GNU). 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 the supported BSD operating systems (NetBSD, FreeBSD, OpenBSD, DragonflyBSD).

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.

-cpus
    Force the display of a single meter for all CPUs in the system. This option is equivalent to setting xosview*cpuFormat to "single".

+cpus
    Force the display of all CPUs in the system. This option is equivalent to setting xosview*cpuFormat to "all".

-network maxbandwidth
-networkBW maxbandwidth
-networkBandwidth maxbandwidth
    These options override the xosview*netBandwidth 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.

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

-ints +ints
-interrupts +interrupts
    Equivalent to -int and +int.

-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. This is a bitmap font rendered at the X server. To list the available fonts, use xlsfonts(1), and rehash the list with xset(1).

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*loadProcColor: color
    This is the color that the load meter will use to display the load average when it is below the warning threshold.

xosview*loadWarnColor: color
    This is the color that the load meter will use once the load average is above the warning but below the critical load threshold.

xosview*loadCritColor: color
    This is the color that the load meter will use once the load average is above critical load threshold.

xosview*loadWarnThreshold: int
    This number (which must be an integer >= 1) sets the value at which the loadmeter changes its status and color from "normal" to "warning". The default value is the number of processors.

xosview*loadCritThreshold: int
    This number (which must be an integer >= 1) sets the value at which the loadmeter changes its status and color from "warning" to "critical". The default value is four times the warning threshold.

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

xosview*loadCpuSpeed: (True or False)
    Display the current CPU speed in the load meter.

CPU Meter Resources

xosview*cpu: (True or False)
    If True then xosview will display a cpu meter. On Linux, *BSD, Solaris and IRIX SMP machines, the resource cpuFormat defines how meters are created for multiple CPUs.

xosview*cpuFormat: (single, all, both or auto)
    If `single', only a cumulative meter for all CPU usage is created. `all' creates a meter for each CPU, but no cumulative meter. `both' creates one cumulative meter and one for each CPU. `auto' makes a choice based on the number of CPUs found.

xosview*cpuFields: USED/USR/NIC/SYS/INT/SI/HI/WIO/GST/NGS/STL/IDLE
    The set of fields to show in Linux CPU meter instead of the default. Possible fields are:

    USED:
        Combine all used CPU time into one field. This is the sum of user, nice, system, soft and hard interrupts, guest, niced guest and stolen times. None of these, except stolen, may be defined together with `USED'.
    IDLE:
        Time spent doing nothing. Includes I/O wait if it is not defined separately.
    USR:
        Time spent in user mode processes. Includes nice, guest and niced guest if those are not defined separately.
    NIC:
        Time spent in niced user mode processes. Includes niced guest if neither it nor guest is not defined separately.
    SYS:
        Time spent in kernel code. Includes soft and hard interrupt as well as stolen time if those are not defined separately.
    INT:
        Combines soft and hard interrupt handling times into one field.
    SI:
        Time the kernel used to handle soft interrupts. Available on Linux kernel 2.6.0 and higher.
    HI:
        Time the kernel used to handle hard interrupts. Available on Linux kernel 2.6.0 and higher.
    WIO:
        Time spent waiting for I/O to complete. Available on Linux kernel 2.6.0 and higher.
    GST:
        Time spent running guest OS in virtual machine. Includes niced guest if it is not defined separately. Available on Linux kernel 2.6.24 and higher.
    NGS:
        Time spent running niced guest OS in virtual machine. Available on Linux kernel 2.6.32 and higher.
    STL:
        Involuntary wait time when running as guest in virtual machine. Available on Linux kernel 2.6.11 and higher.

    Most combinations are possible (see above for restrictions), but at least `USED' or `USR' and `SYS' need to be defined. `IDLE' field is added automatically.

Memory Meter Resources

Swap Meter Resources

Page Swapping Meter Resources

xosview*pageBandWidth: maxEvents
    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).

Gfx Meter Resources

xosview*gfx:    (True or False)
    If True xosview will display the GfxMeter. The value is sampled once per second, due to the usage of sadc to sample data.

xosview*gfxWarnColor: color
    This is the color that the gfx meter will use once the warn state is reached.

xosview*gfxAlarmColor: color
    This is the color that the gfx meter will use once the alarm state is reached.

xosview*gfxSwapColor: color
    This is the color that the gfx meter will use in normal state

xosview*gfxWarnThreshold: int
    This number (which must be an integer >= 1) of swapbuffers per second and pipe at which the gfxmeter changes its status and color from "normal" to "warn". The default value is 60.

xosview*gfxAlarmThreshold: int
    This number (which must be an integer >= gfxWarnThreshold) of swapbuffers per second and pipe at which the gfxmeter changes its status and color from "warn" to "alarm". The default value is 120.

xosview*gfxDecay: (True or False)
    You should probably leave this at the default value (False). The gfx does not work in decay mode.

Network Meter Resources

xosview*net: (True or False)
    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.

xosview*netBandwidth: maxBytes
    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% incoming, 75% outgoing).

xosview*netIface: interface
    If False, xosview will display the data received/transmitted by any of the network interfaces. Otherwise, xosview will only display the data received/transmitted by the specified network interface. If the name is prepended with '-' sign, the data in that interface is ignored.

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

NFSStats (Client) Resources

xosview*NFSStats: (True or False)
    If True then xosview will display a meter to monitor NFS client stats.

xosview*NFSStatReTransColor: color
    The color to be used for retransmit stats.

xosview*NFSStatAuthRefrshColor:    color
    The color to be used for auth refresh stats.

xosview*NFSStatCallsColor: color
    The color to be used for call stats.

xosview*NFSStatIdleColor: color
    The color to be used for idle stats.

NFSDStats (Server) Resources

xosview*NFSDStats: (True or False)
    If True xosview will display a meter for NFS server/daemon stats.

xosview*NFSDStatCallsColor: color
    The color to be used for call stats.

xosview*NFSDStatBadCallsColor: color
    The color to be used for bad stats.

xosview*NFSDStatUDPColor: color
    The color to be used for UDP stats.

xosview*NFSDStatTCPColor: color
    The color to be used for TCP stats.

xosview*NFSDStatIdleColor: color
    The color to be used for idle stats.

Serial Meter Resources

xosview*serial(0-9): (True, False, or portBase)
    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.

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

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

Interrupt Meter Resources

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

xosview*intSeparate: (True of False)
    If True then xosview will display one interrupt meter per CPU on SMP machines. If False only one meter is displayed. Default: True.

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

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

Interrupt Rate Meter Resources

xosview*irqrate: (True or False)
    If True then xosview will display an interrupt rate meter.

xosview*irqrateUsedColor: color
    This is the color that will be used to show the interrupt rate.

Lm Sensors Resources

xosview*lmstempHighest: number
    Highest value displayed. If not given, or too small, the meter will adjust to fit actual and alarm values. Can be overridden for any meter with lmstempHighestN.

xosview*lmstempActColor: color
    Color of actual value.

xosview*lmstempHighColor: color
    Color above high alarm value, also used to indicate alarm.

xosview*lmstempLowColor: color
    Color of actual value, when it is below low alarm value.

xosview*lmstempIdleColor: color
    Color between actual and high alarm values.

xosview*lmstempN: filename
    Name of input file from /proc/sys/dev/sensors/*/* or /sys/class/hwmon/*/{,device}/, N=1,2,3,... Can also be absolute path. For example,
    xosview*lmstemp1: temp1
    xosview*lmstemp2: temp2_input

    Note: Many sensors have the value and alarm threshold in files named "*_input" and "*_max"/"*_min", respectively. In such case, specifying the base name such as "temp1" here will be enough for having both files used.

    Note: If the same file name as lmstempN, lmshighN or lmslowN exists in other sensor directories, then lmsnameN needs to be specified, or absolute path used, to find the correct one.

xosview*lmshighN: filename or number
    Optional high alarm value or name of file from /sys/class/hwmon/*/{,device}/, N=1,2,3,... Can also be absolute path. If not given, lmstempHighest is used as both maximum and high alarm. For example,
    xosview*lmshigh1: 70
    xosview*lmshigh2: temp1_crit_hyst

xosview*lmslowN: filename or number
    Optional low alarm value or name of file from /sys/class/hwmon/*/{,device}/, N=1,2,3,... Can also be absolute path. Default is 0. For example,
    xosview*lmslow1: 1.5
    xosview*lmslow2: fan1_min

xosview*lmsnameN: name
    Optional name of the sensor device to use when finding the filename(s) given in lmstempN, lmshighN and lmslowN. See /sys/class/hwmon/*/{,device}/name for the names of your sensors. This has no effect to files given as absolute paths. For example,
    xosview*lmsname1: nct6779
    xosview*lmsname2: radeon

xosview*lmstempLabelN: string
    N-th label for above values, default is TMP.

xosview*lmstempHighestN: number
    Override default lmstempHighest for meter N.

xosview*lmstempUsedFormatN: (float, percent or autoscale)
    Override default lmstempUsedFormat for meter N.

ACPI Temperature Resources

xosview*acpitempHighest: 100
    Highest temp value displayed, default 100. If acpihighN is given, the value is read from there instead.

xosview*acpitempActColor: color
    Color of actual temperature.

xosview*acpitempHighColor: color
    Color above alarm temperature, also used to indicate alarm.

xosview*acpitempIdleColor: color
    Color between actual and alarm temperatures.

xosview*acpitempN: filename
    Name of temperature file from /proc/acpi/thermal_zone or /sys/devices/virtual/thermal. Note that the last directory part must be given, e.g. TZ0/temperature. Absolute path can also be used.

xosview*acpihighN: filename
    Name of high value/trip point file from /proc/acpi/thermal_zone or /sys/devices/virtual/thermal, or an absolute path to one.

xosview*acpitempLabelN: Labelstring
    N-th label for above temperatures, default is TMP.

Intel Core / AMD K8+ / VIA C7 Temperature Sensor Resources

xosview*coretempHighest: 100
    Highest temp value displayed, default 100. If CPU throttling temperature (tjMax) is supplied by the operating system, it is used instead.

xosview*coretempHigh: number
    Value to use as alarm temperature, default is coretempHighest. If a usable value, such as the temperature for which maximum cooling is required, is supplied by the operating system, it is used instead.

xosview*coretempActColor: color
    Color of actual temperature.

xosview*coretempHighColor: color
    Color above alarm temperature, also used to indicate alarm.

xosview*coretempIdleColor: color
    Color between actual and alarm temperatures.

xosview*coretempDisplayType: (separate, average or maximum)
    This resource tells xosview how to display the CPU temperature. The formats work as follows:

    separate:
        Display one meter for each CPU core of a multi-core CPU. This is the default.
    average:
        Display the average of core temperatures of a multi-core CPU. On multi-socket machines, one meter per physical CPU is displayed.
    maximum:
        Display the highest core temperature of a multi-core CPU. On multi-socket machines, one meter per physical CPU is displayed.

*BSD Sensor Resources

xosview*bsdsensorHighest: number
    Highest value displayed. If not given, or too small, the meter will adjust to fit actual and alarm values. Can be overridden for any meter with bsdsensorHighestN.

xosview*bsdsensorActColor: color
    Color of actual value.

xosview*bsdsensorHighColor: color
    Color above high alarm value, also used to indicate alarm.

xosview*bsdsensorLowColor: color
    Color of actual value, when it is below low alarm value.

xosview*bsdsensorIdleColor: color
    Color between actual and high alarm values.

xosview*bsdsensorN: name.type
xosview*bsdsensorHighN: name.type
xosview*bsdsensorLowN: name.type
    These define where the actual value, high alarm value and low alarm value for meter N=1,2,3,... will be read from. The name is the sensor driver, and type is the wanted value. Both alarm values are optional, and can also be given as static numerical values.

    You can find the correct pair for OpenBSD and DragonFly BSD with systat command, e.g.
    xosview*bsdsensor1: it0.temp1
    xosview*bsdsensorHigh1: 100

    On NetBSD, you can find the driver name with envstat command. Value name for the actual reading is typically 'cur-value' and for high alarm 'critical-max' and for low alarm 'critical-min', e.g.
    xosview*bsdsensor2: coretemp0.cur-value
    xosview*bsdsensorHigh2: coretemp0.critical-max

    For all possible NetBSD value names, refer to envstat source code.

    FreeBSD has no usable sensor drivers as of version 9.0. However, ACPI thermal zones can be used by defining the sysctl node below hw.acpi.thermal, e.g.
    xosview*bsdsensor1: tz0.temperature
    xosview*bsdsensorHigh1: tz0._CRT

    ACPI thermal zones can be used like this on DragonFly BSD as well.

xosview*bsdsensorLabelN: string
    N-th label for above meters, default is SENN.

xosview*bsdsensorHighestN: number
    Override default bsdsensorHighest for meter N.

xosview*bsdsensorUsedFormatN: (float, percent or autoscale)
    Override default bsdsensorUsedFormat for meter N.

Battery Meter Resources

xosview*battery: (True or False)
    If True then xosview will display a battery meter. Linux users will need to have APM or ACPI support in their kernels for this to work. For both APM and ACPI, xosview shows the status/sum of all batteries. Additionally - the legend text gets changed/adjusted to reflect the current state (charging/low/critical/etc.) of the battery/batteries.

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

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

xosview*batteryChargeColor: color
    This is the color that will be used as 'left' - if the batteries get charged.

xosview*batteryFullColor: color
    This is the color that will be used as 'left' - if the batteries are fully charged. APM and ACPI does provide this info, but not all machines actually do so.

xosview*batteryLowColor: color
    APM only - the 'left' color that will indicate a low battery. Depends on the machine - e.g. below 25% remaining capacity.

xosview*batteryCritColor: color
    APM case: the 'left' color if APM indicates 'critical' state. (less than 5%) ACPI case: the 'left' color if the remaining capacity is below the alarm value. (which can be set by the user in /proc/acpi/battery/BAT[01]/alarm )

xosview*batteryNoneColor: color
    If no battery is present - or all batteries get removed (while on AC).

Wireless Meter Resources

xosview*wireless: (True or False)
    If True then xosview will display the link quality of each wireless connection. Note that the graph will *never* show up, if you don't have any wireless devices, or no wireless extensions in the kernel (/proc/net/wireless). Default is true.

xosview*PoorQualityColor: color
    This is the color for the quality field when between 0 and 6.

xosview*FairQualityColor: color
    This is the color for the quality field when between 7 and 14.

xosview*GoodQualityColor: color
    This is the color for the quality field when higher than 14.

xosview*wirelessUsedColor: color
    This is the background color.

Disk Meter Resources

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

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

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

RAID Meter Resources

xosview*RAIDdevicecount: int
    Please enter your RAID device count (n) here or 0 if you don't have any supported RAID devices. xosview then will display n RAID state displays.

xosview*RAIDdiskOnlineColor: color

xosview*RAIDdiskFailureColor: color
    These colors will be used for indicating working/online or failed/offline disks. The order (from left to right) is the same as in /proc/mdstat.

xosview*RAIDresyncdoneColor: color

xosview*RAIDresynctodoColor: color

xosview*RAIDresynccompleteColor: color
    If a resync/rebuild of the RAID array is in progress, the "done" and "todo" colors will be used. If no rebuild/resync is running, then the "complete" color will be shown.
