I understand that there would be complications with altering rrdtool such that it could handle different types of data, but the reason I first started using it was for its (superior :) graphing capabilities. I looked high and low for a similar 'free' tool to create graphs and found none. I would like to see rrdtool extended to handle time data that occurs more than once a second, or where an accuracy of greater than once a second is required. > <snip> >>3. Make it possible to get all input from standard in, not from file.rrd It is a small trade off to create an rrd first before creating the graph, but I would be curious to see how a stdin interface to rrdgraph, much like rrdtool update, would work (my data comes all at once with time stamps). But then thinking about it, rrdtool would have to store this data somewhere anyway while it was waiting for it to finish arriving, hence an rrd! > <snip> -- Iain Buchanan -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
