As clusters are in bigtop, creating the system there and update for review.

PR Changes includes these:

• Added variable for consistency group
• Added panel of Consistency Group in Highlights which shows count of cg and can be filtered by CG var
• Added Consistency Group Data Protection Analysis per Cluster panels which can be filtered by CG var.

This comment is not part of this PR, but it's something that could be improved if possible in seperate PR.

Given that SnapMirror is not node-driven, could we also consider removing destinationNode and sourceNode dropdowns. They are used as filter in 'SnapMirror per Node' section? This change might reduce the number of dropdowns in the dashboard and simplify the dashboard.

[Hardikl]

Sure, We can discuss this in meeting.

Merged 2 tables for snapmirror

Merged 2 tables for CG

pending item:

• filtering in highlights table based on CG var

[Hardikl]

Supporting Top $TopResources Last Transfers by Transfer Data Size table filter with CG var,

Just to note,
There are 3 queries in table and below graphs, snapmirror_last_transfer_duration, snapmirror_last_transfer_size and snapmirror_lag_time. If any point in time the metrics won't be available for that relationship(there may be many reason as no lag or no successful transfer or unhealthy relationhsip, etc..), then it won't be visible in the table/graph.

[Hardikl]

After hide the node vars, validated that all the panels were populated as expected after hiding them.

[Hardikl]

Added sourceConsistencyGroup and DestinationConsistencyGroup variables.

[Hardikl]

Updated the UI panels to accommodate the flexgroup panel count.

Added decent documentation of all kind of relationships.
