[rrd-users] YAI: Viewing rrd file details over the web.

Yet Another Idea (YAI): Allowing end users of an RRD-driven MRTG
collection to view not only the MRTG graphs but also the data collection
in detail.

One way to do it (which I'm going to try out with 14all.cgi eventually)
is do create this on the server side and then return the output from
rrdfetch or rrddump (partially preferably as those files are pretty

Another way is to have a Java applet available which will allow the
intrested user to look at the details.  For each collection, have the
option of "viewing graph data".  When that link is followed, a page
opens up with this RRD-applet which upon load do fetch the actual
RRD-file (which is just a 97K file).  Once that is done, the applet
allows you to walk around in the graphs, zoom in on some specific period
of time or perhaps view the exact sample values at specific points in
time.  There are quite some possibilities here.

Also, when we are at providing rrd-file data details to the users, you
could consider to let a filter use the rrd-file to create a presentation
in a Excel or Star office spreadsheet or any other nice kind of
format.   What those filters should look like, I don't know, to be
frank, but still...

(so easy to get all these ideas, so little time to implement them...)

Best regards
