Giving an alias to the to the data points in the CM charts

[#1]

Hi,

I have 6 datanodes and if I run this chart query:

select impala_admission_controller_local_num_admitted_running WHERE poolName="root.default"

I get six lines on my graph.  But each one has a human unfriendly name like:

impala-IMPALAD-00a06701e5a2bac3b893e59fde762af5:root.default

How to I get that display that name as the real hostname ?

Thanks
