Hi all,
I’m working with a relatively new install, and I’m running into two problems. The first problem is no graphs anywhere are being generated.
Here’s a RRDTool Command from one of the graphs:

RRDTool Output
1105x612
OK u:0.14 s:0.02 r:0.16
The other problem, and probably more severe one, is a memory leak that I appear to be incurring. I think I fixed this by enabling selective port polling globally, but I’m not sure that was the best idea. There appears to be about 100 rrdtool processes running.
Here’s the validate.php output:
