I have installed marvel as plugin but I can't see any data. I see only error message "No results There were no results because no indices were found that match your selected time span". Other plugins like http://www.elastichq.org/support_plugin.html works fine.
My cluster name is differ from default, may be this is reason?
Did you restart ES after installing it?
You should see something like loaded [marvel], sites [marvel] in your logs to show that it has been correctly loaded.
