[Acronym] for __S__imple __N__etwork __M__anagement __P__rotocol.

A easy way to retrieve data from a device, simple enough to be implemented in almost anything.  Your [ADSL] router probably speaks [SNMP], network printers support [SNMP] etc.  If you have a device that has [SNMP] try the commands:

<pre>
 snmpwalk  ''ip.of.machine'' public .
 snmptable ''ip.of.machine'' public udp.udpTable
 snmptable ''ip.of.machine'' public ip.ipNetToMediaTable
 snmptable ''ip.of.machine'' public ip.ipRouteTable
 snmptable ''ip.of.machine'' public ip.ipAddrTable
 snmptable ''ip.of.machine'' public interfaces.ifTable
 snmptable ''ip.of.machine'' public tcp.tcpConnEntry
 snmptable ''ip.of.machine'' public host.hrStorage.hrStorageTable
</pre>

(change public if you know the community name is something else) to see all the information you can get out of [SNMP].

There are lots of programs that will graph from [SNMP], including [MRTG] and [rrdtool].  There are some nice wrappers around these tools like cricket and [Cacti] (I highly recommend [Cacti], it's pretty)
