It's not clear what you mean by "an entire separate ganglia installation", but given the way you've phrased the question, the answer may be both yes and no. Each grid corresponds to one gmetad process, so you can't have multiple grids on one gmetad. You can have multiple gmetads on the same host if you configure them to use different rrd_rootdir's and listen on different ports, though usually people put each gmetad on a separate host. One gmetad can collect data from other gmetad hosts, and make a "grid of grids". Ganglia-web will look at an rrd_rootdir and show you the stuff in there. You define the directory to look at in conf.php as: $gmetad_root = "/path..."; and by default it's set to the same /var/lib/rrds as gmetad's default, but you can make it point at any rrd_rootdir that one of your gmetad processes maintains and it will work. That could be a single grid or a grid of grids. Or you could hack up a simple way to select from one of several predefined $gmetad_root values, via the web, and have a single browser for multiple rrd trees. -- Cos ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
