Re: [Ganglia-developers] ganglia.h cannot be compiled with C++
Hi, Bemard Thanks for the reply. Wrapping in C first, and use them will work for C++ application, but not ideal solution.

The documentation I provided is for writing gmond C modules, however we do support writing modules in C++ at least according to the release notes: http://sourceforge.net/apps/trac/ganglia/wiki/ganglia_release_notes#GangliaRelease3.1.1 Perhaps you can use the guide and try writing a C++ module and see if you can make it work? I also found this thread, perhaps it will come in handy: http://www.mail-archive.com/ganglia-developers@lists.sourceforge.net/msg05278.html On the other hand, it looks like you're trying to write a C++ program using ganglia header files, that is not the same as writing a C++ gmond module. You need to figure out whether writing a module will work in your case.

[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.

What about formatting like this: { metric: cpu_num, color: 00FF00, label: Nodes, line_width: 2, type: line, DS: num, contexts: [cluster, meta] } You could implement with: if ( isSet($item[ 'contexts' ]) array_key_exists($context, $item['contexts']) ) { continue; } The context names seem like data here, not keys, so I just thought an array might be more appropriate. Yes, it is much simpler now. Markus Ah, yeah, especially since my suggested change implemented the opposite of your idea. Oops. :) Also, I'm remembering to reply to everyone this time. alex -- Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
