NAME

perfmeter − meter display of system performance values

SYNOPSIS

perfmeter [ −s sample-time ] [ −h h-hand-int ] [ −m m-hand-int ]

[ −M smax minmax maxmax ] [ −v value ] [ hostname ]

DESCRIPTION

perfmeter starts a tool whose iconic form is a meter displaying a system performance value, and whose open form is a strip chart of that value.  By default, the meter is updated with a sample-time of 2 seconds.  The hour hand represents the average over a 20-second interval; the minute hand, an average over 2 seconds. The default value displayed is the percent of cpu being utilized. 

These defaults can be modified with command line options, or dynamically after the tool has been started using a popup menu. 

If there is no hostname argument, then the data displayed will be for the local host.  In either case, the rstatd(8C) daemon must be running on the machine for which statistics are being reported. 

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 to one of:

cpupercent of cpu being utilized

pktsethernet packets per second

pagepaging activity in pages per second

swapjobs swapped per second

intrnumber of device interrupts per second

diskdisk traffic in transfers per second

cntxtnumber of context switches per second

loadaverage number of jobs running on the server over the last minute

collscollisions per second detected on the ethernet

errserrors per second on receiving packets

COMMANDS

The value being displayed can be changed by clicking the tool with the rightmost mouse button, and then selecting the appropriate menu item.  The other meter parameters can be modified by moving the mouse cursor into the tool (either open or closed), and typing:

mdecreases minutehandintv by one

Mincreases minutehandintv by one

hdecreases hourhandintv by one

Hincreases hourhandintv by one

1-9Sets sampletime to a range from 1 to 9 seconds.
