[Ganglia-developers] let Grid and Cluster Load graphs at the web 2.0 interface lock like at the old interface
Attached is a patch to let the Grid and Cluster Load graphs lock like at the
old interface.
Add possibility to define a custom data source in the json template with DS
which will get used instead of the default 'sum'. To handle situations where
the data source is not available in all rrds define the context.
For example the number of Nodes:
data source 'num' only available in the summary rrds of 'cpu_num'
definition in the json template looks like:
{ metric: cpu_num, color: 00FF00, label: Nodes, line_width: 2,
type: line, DS: num, context:
{ cluster: true, meta: true } }
The metric will get ignored at the host context but not at the meta and
cluster context.

Re: [Ganglia-developers] Web 2.0 UI code freeze

I spoke to Bernard and we are considering doing a code freeze of the Web

Thoughts ?
Excellent work!
I did some small modifications:
- remove config option $conf['show_cores'] (There is no code which will use
it)
- link to the graph_all_periods.php at the grid overview (like at the cluster
overview)
- at graph_all_periods.php link the graphs to graph.php (like at the grid
overview)
