sysmon, stats - display graphs of system activity
sysmon [ machine [ -option ] ]
stats [ -option ]
Sysmon displays a rolling graph of various statistics collected 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 a
mouse button anywhere in the window cycles through the list of parameters to monitor; an
option letter sets the initial choice. The option letters and parameters are:
total pages of active memory. The memory is displayed as a fraction of the
machine's total memory.
number of packets sent and received per second.
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.
number of process context switches per second.
number of interrupts per second.
number of memory faults per second.
number of translation look-aside buffer misses per second.
number of translation lookaside buffer flushes per second.
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.
Some machines do not have TLB hardware.
