I setupped ganglia and configured gmetric to collect some metrics with node spoofing. Theese virtuals metrics are collected, I able to see separate graphs of metrics for each node. I created summary graphs for metrics, but they are empty. I looked into rrds in SummaryInfo, they are filled with Nan values:

<!-- 2011-11-17 14:43:45 MSK / 1321526625 --> <row><v>NaN</v><v>NaN</v></row>

Please tell me how to fix it. If you need some configs I can attach them.

How did you create summary graph? – quanta Dec 1 '11 at 8:45
Please attach your gmetad config, if you don't mind. That will help us troubleshoot. – Handyman5 Dec 4 '11 at 9:08
