SYSMON(8) SYSMON(8)
NAME
sysmon, stats - display graphs of system activity
SYNOPSIS
sysmon [ machine ]
stats
DESCRIPTION
Sysmon displays a rolling graph of various statistics col-
lected by the operating system. The statistics may be from
a remote machine. A sample value is taken once per second.
The number in the top left corner of the graph gives the
peak value for the duration of the graph.
Lines across the graph represent 75%, 50% and 25% of the
peak value. Clicking the mouse buttons anywhere in the win-
dow selects a new parameter to monitor. The parameters are:
mem total pages of active memory. The memory is dis-
played as a fraction of the machine's total mem-
ory.
ether number of packets sent and received per second.
swap number of valid pages on the swap device. The
swap is displayed as a fraction of the number of
swap pages configured by the machine.
contxt number of process context switches per second.
intr number of interrupts per second.
fault number of memory faults per second.
tlbmiss number translation lookaside buffer misses per
second.
tlbpurge number translation lookaside buffer flushes per
second.
load system load average. The load is computed as a
running average of the number of processes ready
to run multiplied by 1000 to give some precision.
The stats program is invoked by sysmon to display the graph.
