Hey Alex,
Ahh, that's a interesting feature.
I would very much like to see this get it's way into the source code, as
I want similar functionality for some other metrics.
These are called 'report's in Ganglia, btw.
The seperate interface idea sounds good.
I would suggest to move this discussion to the Ganglia-developers
mailing list, you might get some more feedback there.
Kind regards,
- Ramon.

Say I added 10 gmetrics for NFS. These metrics would appear in the
relevant node's graphs.
However, I would not have such graphs in cluster/grid view. This makes
sense as Ganglia has no way of knowing which gmetrics to group in each
graph and what graphical parameters to use for presenting them.
I'm looking to implement a web interface which lists all metrics
(builtin and gmetrics) present in the SummaryInfo for each cluster/grid,
and allows the user to choose which metrics to group in the aggregation
graph.
For example, the list of metrics could be:
cpu_wio
nfs_read
nfs_write
nfs_getattr
....
And the user could choose:
cpu_wio - red - line
nfs_read - green - line
nfs_write - blue - line
The system would then generate the summary graph based on these selected
metrics (along with some other required parameters).
Thanks,
Alex

Hi all,
I'm interested in viewing data gathered from gmetrics in a
cluster/grid
view, sort of like the aggregation graphs for load/memory. This would
require some changes to the web frontend code and I'd like to know,
has
anyone here made such changes?
I've written a quick & dirty hack that provides this functionality
(only
cluster-view at the moment) but it requires entering arguments to
rrdtool into some array in conf.php. Needless to say that's way too
ugly
to go in a production environment.
My plan is to write a separate interface in which one could choose
the
desired gmetrics, color, graph style and time interval, and the
graphs
would be generated accordingly. This interface will be linked from
each
cluster/grid view and would display the desired graphs for that view.
Your thoughts (and patches..) will be appreciated!
Cheers,
Alex

There are really only three types of people:
Those who make things happen, those who watch things happen
and those who say, "What happened?"
