I put owfs and temploggerd on an NSLU2 running Debian 4.0r2. Owfs is working, but I couldn't get any of the temploggerd web pages. I traced the problem down to the rrdtool graph function, and for certain parameters it takes a terribly long time to generate pages. Temploggerd generates a cgi file that has an RRD::GRAPH tag to generate the graph image, and that includes instructions to print out the average, min, max and last. I ran the equivalent by running "rddtool graph" by hand, printing out only the max. It turns out that a graph that includes
PRINT:2629A880000000tempe:MAX:"%5.1lf C" makes it take 37 minutes to generate the image. If I remove that instruction, it takes 5.7 seconds to generate the image. I tried the version of rrdtools installed by aptitude (1.2.15), and even compiled the latest (1.2.26), and both act the same. Interestingly enough, the print directives work fine on my NSLU2 unit running Unslung 6.8. Some difference between big- and little-ending versions?
