Adding a second or third poller on the same server?

[GlueGuy]

I've been looking around for information on how to set up a second poller on the same server. In this particular case, we want some critical systems to be polled on a 1-minute interval, but other less-critical systems polled on a 5-minute interval.

Just looking at the poller.php and config.php files, my initial thought is that I would have to install two separate installations of cacti, but that doesn't make sense.

Can someone point me to the overview on how this is done?

TIA

You don't need separate pollers on the same system, you should instead setup RRD Profiles for faster times, and utilize those on separate data sources for the other hosts. Then set your poller to fastest time.
