-----------------------------------------
Thanks [~wangda],
Regarding the approach to display i had few concerns :
* There will be some common queue metrics across the labels, wont it get
repeated across for each label if a queue is mapped to multiple labels ?
* IIUC most of the queue Metrics might not be specific to a label, like
Capacity, Absolute max capacity, Max apps, Max AM's per user etc... . Correct
me if my understanding on this is wrong.
* Apart from the label specific queue metrics like (label capacity, label abs
capacity,used) are there any new Label specific queue metrics you have in your
mind ?
* would it be better to list like
{noformat}
+ root [=====================] 30% used
+ a [=======================================] 75% used
+ a1 [=================] 30% used
---------------------------------------------
| Queue Metrics |
|--------------------------------------------|
| metrics1 | value1 |
| metrics2 | value2 |
---------------------------------------------
| Active Users info (yarn-3273) |
|--------------------------------------------|
| user1 | info |
| user2 | info |
---------------------------------------------
| Label Resource usage info |
|--------------------------------------------|
| label_x [=====================] 30% used |
| label_y [================] 20% used |
----------------------------------------------
+ a2 [=================] 30% used
...
{noformat}
* Also if required we can have seperate page (/in the labels page/append at the
end of CS page) like :
{noformat}
+ label_x [=====================] 30% used [Actual Resource - Used resource ]
+ root [=====================] 30% used [Actual Resource - Used
resource ]
+ a [=======================================] 75% used [Actual
Resource - Used resource ]
+ a1 [=================] 30% used [Actual Resource - Used resource
]
+ label_y
+ root [...]
+ ...
+ label_z
+ root [...]
{noformat}
YARN-3273, has added more info to the CS page so we need to consider the size
of page and its usability.
Please provide your thoughts on the same
