[Ganglia-developers] whishlist: compare a metric from two (arbitrary?) periods
Hello, today I was playing with the timeshift overlay for metrics and I like it. I have a system, where regular jobs are scheduled once a month (swinging some days back and forth, as the start is always on the same weekday) or once every two weeks. I've added a fortnight period to $conf['time_ranges'] for the two week schedule. I have a useful overlay for these periods. For the other, more volatile schedule it would be useful to have an option to select start (and end) for the original metric and the start for the period to compare to. Right now I don't see where this could be implemented in the ganglia wabfrontend. Any ideas?

[Ganglia-developers] [PATCH] Make size of optional graphs in cluster / host view configurable
We'd like to have the optional graphs in the cluster and host view
bigger. In the past, I just modified cluster_view.php and
host_view.php. To avoid that modification and forward porting of my
changes I've added a new configuration option.
Comments are welcome.

Re: [Ganglia-developers] bacula: graph backup-size per client in ganglia

[Ganglia-developers] add extras parsing to json graph-definitions
Hi,
I'm working on getting ganglia to display correct units for one
custom graph. One of the first tries was to give some extra option
to rrdtools.
When using php-graphs, this is done via $rrdtool_graph[ 'extras' ],
but there is nothing for json graphs.
That simple patch (against 3.4.2) should fix that:
