why not add them to $optional_graphs in web/conf.php instead? I agree with you that at the end it might make more sense to treat all the reporting graphs the same regardless of if they are custom or part of the core just like metrics are treated now in 3.1 > However, it'd also be really useful to: > > 1. See the custom graphs relevant to a cluster show up in the cluster > view at the top, summarizing or totaling the whole cluster agree, but you are going to have to be able to configure which reports you want to have per cluster (as you will most likely need different reports in each cluster) otherwise you can just change the template (web/templates/default/cluster_view.tpl) to show the list of reports you are interested for all cluster pages (in that case is probably a good idea to create your own template name and refer to it in conf.php) > 2. See those graphs in the grid view, in each cluster's summary if it is the same list for all clusters can be done in the template (web/templates/default/meta_view.tpl), if you want a different list per cluster then you could probably use the same configuration defined above, but could get difficult to handle and to understand as space is limited in the grid view per cluster and is IMHO useful to have all cluster reporting the same metric vertically so you can see global trends easily. > 3.
