[rrd-users] Re: Sparklines in RRD ?

[Woods, Craig]

100% correct if I was using the Sparklines php module. In fact, I only provided that link because it was a very concise and informative description of what a sparkline _is_, and how to use it. 

I rely on RRDgraph to produce graphs from RRD data - I just want them to be very small graphs, with the appropriate resolution and adjunct textual information.

I agree that some of the requirements do not _have_ to be integrated in the RRDgraph command, since they are technically external to the graph itself. E.g. the 'grid' layout, with text labels before and after the chart, and the ability to stack the charts & labels). But since the labels contain information from the RRDgraph command (like the Min, Max, Avg, Last data points, e.g.), I can also envision RRDGraph commands for creating 'sparkline' formated graphs.

Stop me if I'm way out in left field but...

It seems to me that you are only looking to RRDTool for data storage.  If this is true, you can collect your data and store it in an RRD (using whatever method you choose) and then roll your own PHP script to display using Sparklines utilizing rrdfetch to retrieve data from your RRD file.

Sparklines does not care where the data came from, just that it gets fed an array of data points.

Craig,

you should definitly go for rrdtool 1.2 since it has the only-graph option as well as support for --zoom which lets you zoom your graphs to your hearts delight ... you can also switch of the grid to get some thing sort of like what is on that webpage ..

cheers

so when I build very small graphs, I still get the background, with a relatively large buffer on the left of the chart.
