Also, memory is so cheap these days, why not use add a lot of memory, 16GB total for example, and have plenty of headroom.
I don't know the criticality of the application, but for the unix.com server, I like to have double the memory the system typically requires, for those days when things go south on the net or a process hangs, etc.
Hi all
I currently use the following in shell.
#!/bin/sh

sysmon
SYSMON(8) System Manager's Manual SYSMON(8)NAME
sysmon, stats - display graphs of system activity
SYNOPSIS
sysmon [ machine [ -option ] ]
stats [ -option ]
DESCRIPTION
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:
[m] mem
total pages of active memory. The memory is displayed as a fraction of the machine's total memory.
[e] ether
number of packets sent and received per second.
[w] 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.
[c] contxt
number of process context switches per second.
[i] intr
number of interrupts per second.
[f] fault
number of memory faults per second.
[t] tlbmiss
number of translation look-aside buffer misses per second.
[p] tlbpurge
number of translation lookaside buffer flushes per second.
[l] 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.
FILES
/net/*/[0-n]/stats
#c/sysstat
SOURCE
/rc/bin/sysmon
/sys/src/cmd/stats.c
BUGS
Some machines do not have TLB hardware.
