Description Ben England 2021-09-13 17:49:40 UTC
Description of problem:

(originally reported to me by Matt Currier) 
Flyover panel for Console -> Monitoring -> Metrics GUI interface is useless.   Consequently you cannot evaluate the metric's absolute value at a point in time other than the present (shown in table below the graph).

Version-Release number of selected component (if applicable):

OCP 4.8

How reproducible:

Every time

Steps to Reproduce:
1. Install OCP 4.8
2. fire up a workload utilizing I/O to storage devices
3. try to monitor storage block device throughput 

I don't believe this bug is specific to storage devices, this is just the example I'm using, details below

Actual results:

Flyover panel is useless because you cannot determine which device name and host (instance) corresponded to a particular number.  See the example screenshot below.

Expected results:

I should be able to move my mouse to a point over the x-axis and see all the values in descending order of value, along with the parameters that led to these values.   In this example, the parameters that should be displayed are the ones that are different for each curve, specifically device name and host (instance).

Additional info:

I added a link to a doc.

I'll attach a screen shot that illustrates the problem.  In this case, the metric queries that were being displayed were:

checked with 4.10.0-0.nightly-2021-10-27-230233, searched with "irate(node_disk_writes_completed_total{device=~"nvme[0-9]n1"}[1m])", the labels are ordered intelligently so that those with different values are visible, from the picture, it shows the pod in the first place
