NAME

perfmeter − display system performance values in a meter or strip chart

SYNOPSIS

perfmeter [ −s sample-time ] [ −h h-hand-int ] [ −m m-hand-int ] [ −M smax minmax maxmax ]

[ −v value ] [ hostname ]

AVAILABILITY

Although this command is available with both the SunView  software installation option and the OpenWindows environment its appearance is not the same for both environments. The man page you are currently viewing refers to the perfmeter that is available with OpenWindows. The primary difference between this and the SunView perfmeter is the user interface.  All OpenWindows standard tools use the OPEN LOOK Graphical User Interface. For more information about the OPEN LOOK UI, refer to the OpenWindows User’s Guide.  For information about installing OpenWindows, refer to the OpenWindows Installation and Start-Up Guide. 

DESCRIPTION

perfmeter is an OpenWindows XView utility that displays performance values (statistics) for a given hostname. If no host is specified, statistics on the current host are metered. The rstatd(8C) daemon must be running on the machine being metered. 

When open, perfmeter displays a performance value in the form of a strip chart.  When closed, it displays a meter dial.  By default, the display is updated with a sample-time of 2 seconds.  The hour hand of the meter represents the average over a 20-second interval; the minute hand, the average over 2 seconds. The default value displayed is the percent of CPU being utilized. 

The maximum scale value for the strip chart will automatically double or halve to accommodate increasing or decreasing values for the host machine.  This scale can be restricted to a certain range with the −M option. 

OPTIONS

−s sample-time
Set the sample time to sample-time seconds. 

−h h-hand-int
Set the hour-hand interval to h-hand-int seconds. 

−m m-hand-int
Set the minute hand interval to m-hand-int seconds. 

−M smax minmax maxmax
Set a range of maximum values for the strip chart.  Values for each of the arguments should be powers of 2. smax sets the starting maximum-value.  minmax sets the lowest allowed maximum-value for the scale.  maxmax sets the highest allowed maximum-value. 

−v value
Set the performance value to be monitored by pressing the menu mouse button and sliding the pointer to one of the following options:

cpu Percent of CPU being utilized. 

pkts Ethernet packets per second. 

page Paging activity in pages per second. 

swap Jobs swapped per second. 

intr Number of device interrupts per second. 

disk Disk traffic in transfers per second. 

cntxt Number of context switches per second. 

load Average number of runnable processes over the last minute. 

colls Collisions per second detected on the ethernet. 

errs Errors per second on receiving packets. 

USAGE

Commands

You can change the statistic being displayed by clicking the RIGHT mouse button, and bringing up the property sheet for the tool.  The property sheet will allow you to modify what the perfmeter is monitoring and how often it checks.  Other meter parameters can be modified  through the use of keyboard accelerators. Move the pointer into the window and type one of the following keyboard keys:

m Decrease minutehandintv by one

M Increase minutehandintv by one

h Decrease hourhandintv by one

H Increase hourhandintv by one

1−9 Set sampletime to a range from 1 to 9 seconds.
