How many times/over what period did you run the updates ? You have a step size of 300s (5 minutes), and your most granular consolidated data for MIN and MAX is 12 times that (ie one hour). You'll need to run updates less than 600s (10 minutes) apart until both of the following are true :
- You go "past the hour", since your consolidated data points will all start end on the hour (ie 1am, 2am, and so on)
- You have more than 50% of the preceding primary data points "filled".
This means you must be regularly updating for *AT LEAST* half an hour, and up to almost 1 1/2 hours depending on when you start, before you'll see data.
Use rrdtool fetch ... to see what data is available.
