Today you sent me mail regarding [rrd-users] Re: VISIONARY: New tool to...:
JI> * protocol usage during the day JI> * top talkers during the day JI> * top listeners during the day JI> * top conversation during the day. JI> JI> (It also provides utilization graphs but that's not very intresting as RRDtool JI> VERY easily store and graphs such statistics, as we all know). JI> JI> On each graph, the legend contains colors/patterns to distinguish the topmost JI> candidates for each category. You can configure the reports to provide you with JI> top 10 talkers or top 5 talkers or top 40 talkers etc... any number you like JI> (too many messes up the graph, too few makes you miss some of the host). As you JI> can tell, the legend and the color scheme cannot be decided on advance, as you JI> don't know which hosts/protocols/conversations will be the top 10 (or 5 or 40) JI> contributers to the traffic. It has to be decide upon rendering the image. well I guess the sensible thing to look at for this problem would be some scientific tools for storing and handling sparse matrices ... I bet there are such things available ... cheers tobi JI> > make it probably unpractical with rrdtool, you might want to use a JI> JI> But still RRDtool has some intresting features I really do like and which I JI> would like to see in the new tool and I think borrowing some design and code (if JI> you don't mind of course) could be a good idea.

Actually, you could have something JI> very similar to an RRD but instead of storing values of how much utilization was JI> inbound at each sample period, you store a reference to a data structure which JI> contains what actually was seen during that sample period.

JI> > JI> JI> Ok, here's an example.Well, consider the case you have a WAN link connecting an JI> subsidiary to the rest or the corporate intranet. Suddenly some PC user decides JI> to do some gigantic download. You want the graphs to display not only that the JI> link is near 100% utilized inbound, you also want to see in some graphs WHO is JI> using the major part of the link. JI> JI> Another example is if you have a number of "favourite download servers" JI> somewhere on the intranet, and they become the source of the major portion of JI> traffic traversing the link, you want to the stats to indicate that (so you can JI> consider moving these servers or perhaps start replicate data to local download JI> servers.) JI> JI> The two cases above does imply that not ALL the statistics about traffic over a JI> link is used, we are mainly intrested in what are the biggest contributors. JI> Which might imply that we may do trade-offs in statistic gathering and JI> processing.
