hello every1 ,
I have problem with ganglia . I have a small 2 node cluster + 1 head node.
Problem is ..ganglia web frontend ..does not display any information (the
graphical) about the usage of nodes.
OSCAR = 2.2.1
Ganglia = 2.5.1-1
OS = Redhat 7.3
1)
THIS IS ALL I GET @ my headnode (where gmetad is running) browser :
Overview of Linux_Cluster
There are 3 nodes (3 CPU) up and running.
There are no nodes down.
2)
#> gstat a
