@rajvi-elastic , please complete peer review

@SubhrataK , JFYI, i noticed the change from Donut Chart to Table representation for representing the cluster information and i agree with the change. Hope you are good too.

@rajvi-elastic,

• Please change the description of the issue which represents Redis Enterprise
• When replacing the control filter the current integration enables the Database selection based on the host selection. Are we having the same functionality in the control panel migration. If not is this captured somewhere ?

@SubhrataK - Please let me know your thought process on the mentions below.

• Can we make Node and Cluster Info tables to the fit in the entire screen ?
• The Read Latency, Write Latency and Range Slice Latency all together looks cluttered. Can we realign ?
• Similarly for Storage Exception and Unavailable Requests.

@muthu-mps,

1. Updated the description.
2. No in the new control panels dependency filtering is not possible. We have mentioned this issue in the meta in below format.

In input control visualization, we can make dependency filters that strictly depend on each other but in new controls, dependency filtering is possible but filters are not required to be strict. As per the #4768 (comment), this is the expected behavior of new controls.
Impact : [ Severity : Low, Workaround : No (Expected Behaviour) ]

LGTM!
