stats – display graphs of system activity
The right mouse button presents a menu to enable and disable the display
of various statistics; by default,
percentage battery life remaining.
number of process context switches per second.
draw memory allocation size in bytes.
total number of packets sent and received per second.
number of packets sent and received per second, displayed as separate graphs.
number of page faults per second.
number of interrupts per second.
system load, % time in idle, and % time in interrupts. The last two are averaged over all processors on a multiprocessor.
kernel memory allocation size in bytes.
(default) system load average. The load is computed as a running average of the number of processes ready to run, multiplied by 1000.
total pages of active memory. The graph displays the fraction of the machine’s total memory in use.
number of packets sent and received per second, and total number of errors, displayed as separate graphs.
number of translation lookaside buffer flushes per second.
total pages of reclaimable memory. The graph displays the fraction of the machine’s total memory in use.
number of system calls per second.
number of translation lookaside buffer misses 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.
display the signal strength detected by the 802.11b wireless ether card; the value is usually below 50% unless the receiver is in the same room as the transmitter, so a midrange value represents a strong signal.
The graphs are plotted with time on the horizontal axis. The vertical axes range from 0 to 1000*sleepsecs, multiplied by the number of processors on the machine when appropriate. The only exceptions are memory, and swap space, which display fractions of the total available, system load, which displays a number between 0 and 1000, idle and intr, which display percentages and the Ethernet error count, which goes from 0 to 10.. If the value of the parameter is too large for the visible range, its value is shown in decimal in the upper left corner of the graph.
Upper-case options control details of the display. All graphs are affected; there is no mechanism to affect only one graph.
Set the number of seconds between samples to
Sets a scale factor for the displays. A value of 2, for example, means that the highest value plotted will be twice as large as the default.
Plot all graphs with logarithmic
If the display is large enough to show them,
place value markers along the
Some machines do not have TLB hardware.
