Phil,
imagine some four routers dying or not answering queries, you will see the poll script give you timeout after timeout after timeout and with some 50 to 100 routers and the respective interfaces you see mrtg choke badly, losing data.
You see, the poll script is doing one after the other, mainly, so you wait too long and then the next run starts and then something.
mrtg/rrd is not the tool of choice for accounting / billing but nice enough for showing you 'backup' graphs for visitors probably.
Hi.
From http://people.ee.ethz.ch/~oetiker/webtools/mrtg/reference.html:
Forks (UNIX only) On a system that can fork (UNIX for example) mrtg can fork itself into multiple instances while it is acquiring data via snmp. For situations with high latency or a great number of devices this will speed things up considerably. It will not make things faster though if you query a single switch sitting next door. As far as I know NT can not fork so this option is not available on NT. Example: Forks: 4 Of course, people would have to read the documentation first..
