Description Prasad Mukhedkar 2016-12-13 06:43:51 UTC
Description of problem:

Self_Service portals shows aggregate memory for all the instances of a
service.  There are two memory related matrix displayed.  "Memory"
and "Memory on Disk". Please See attached screenshot attached.

"Memory" corresponds to the aggregated value of vRAM configured but 
there is no info available about  "VM Memory on Disk"?  How "VM Memory 
on Disk" is calculated. What is the use case of this metric.

Hello,

this isn't really a bug per se, it's more I need a question answered.  The best place for that is to go to: https://gitter.im/ManageIQ/manageiq and ask the development team in there.

Re-opening this bug with request to remove the word "disk" from 
the name. 

As per the code , I found :

 def ram_size_in_bytes_by_state
    ram_size_by_state * 1.megabyte
  end



  def ram_size_by_state
    state == 'on' ? ram_size : 0
end


"Memory on Disk", Is the aggregated value of all the running virtual
machines configured memory. if virtual machine is not running, The value
shows 0. 


My Customer believes this term "Memory on Disk" is not suitable for this dashboard. Because there is no disk. Here the average active memory. Or something like that should be set to. I think we should also have infotip/
tooltip displaying brief info of all the matrices .
