We would like to generate reports on per node Impala daemon memory usage for a particualr user over a period of time(like 7 Days). We used the historical queries by user [impala]in reports tab in cloudera manager to generate reports for a specific user but unable to configure parameters like memory_aggregate_peak, coordinator_host_id . It shows invalid attribute error and we are unable to generate reports for users based on their impala daemon memory usage.
Is there any way that we can get report on per node Impala daemon memory usage for a particualr user over a period of time?

You can navigate to CM -> Impala -> Queries -> (Select the history duration from 30min to 30day - Top right) -> "Select Attributes" to customize -> Select User (Bottom left) -> Press "Search" button
You can also generate Chart out of it.

This wont give the total memory usage, it only has peak memory attributes.
Is it possible to get a view such as:
I have 10 daemons, each 40 GB for daemon memory ( so total 400 GB for Impala daemon)
How can I know at any point of time, how much memory out of 400 GB is used?
Also, each impala-daemon:25000/memz gives the memory used in that node but where can I get a collective view?
