I've been having a problem with some data sources being graphed hourly rather than every 10 minutes. I can provide more detailed info (sample data, rrdtool info output, or whatever) if it would be helpful - just let me know what you want to see.
Here's one with the problem... notice that the 3 average values seem to show one combined point per hour, rather than every 10 minutes: http://veggiechinese.net/example2.png compared to my original graph w/ 2 data sources: http://veggiechinese.net/example3.png If I change the cfunc to "max" (from nothing) in the GRAPH statement for the data sources that are average, it seems to graph as expected (though that doesn't seem to be necessary for the rrd with two data sources, which is setup the same way). I'm creating this with RRDTool::OO, but printed the actual commands being issued below. Am I creating this wrong? Should I just use "MAX" as the cfunc in the graph, since I'm already doing averaging for the archive points? Sorry about the weird quoting...
