Dear all,
After a clean install on my cluster on a centos 6.8 ,all works fine (1
head and 28 nodes) except ganglia (3.7).
On each graph, the load of the nodes are shown with the good background
color but no data are drawed and, at the bottom of the graph, this
message is written : *Empty RRDtool command. Likely bad graph config*.
If click on Inspect, no data appear. If i click on JSON, 'null' is
written, and when i export a cvs, i get a file with only 1 line :
'Timestamp'.
I hope somebody will help me ...
Sincerely
Laurent CARREL
