Verification and Validation

• Verification of data count of after-migrated visualization with before-migrated visualization in Kibana
• Verification of Dashboard are not distorted in supported Kibana version (8.3.0)

  [Lens] Support bullet/gauge chart kibana#89859
  Impact : [ Severity : Critical, Workaround : Yes (Convert the panel into either horizontal/vertical gauge chart or metric visualization)]

[rajvi-patel-22]

As discussed with @SubhrataK, We will migrate gauge chart into horizontal/vertical gauge chart or metric type based on the below two scenario.

Scenario 1:
If the panel represents just the metric/count then it will be migrated to the metric visualization.

Before Migration:

After Migration:

Scenario 2:
If the panel represents the CPU Usage or Memory usage which can be represented as a part of whole then we will convert the panel to horizontal/vertical gauge chart.

After migration:

As the workaround suggested is meeting the objective, no concerns in making the proposed changes.

Running the latest Lens migrated version.

Before cluster name drop down:

After Lens Migration, cluster name drop down (version 0.4.0):

What is the extra "Exists" in the drop down? Is this an expected behaviour or some issue?

[lalit-satapathy]

In the Lens version is the info for each of the panel description now gone?

Before:

[rajvi-patel-22]

In the Lens version is the info for each of the panel description now gone?

Yes @lalit-satapathy, By value lens panel doesn't show panel description. [GitHub issue]

Yes @lalit-satapathy, By value lens panel doesn't show panel description. [GitHub issue]

The description seems empty for now and I am able to add them by editing as below.

What is the extra "Exists" in the drop down? Is this an expected behaviour or some issue?

@lalit-satapathy Yes! This is the new functionality added in new control panels. By default the option is enabled. However, we have an option to disable it.

Please find the below screenshot.

@lalit-satapathy, I don't see any option to add description in lens and Kibana issue is also open for the same. Can you please provide steps to add the description so that I can verify it from my end.

Can you also specify the Kibana version that you have?

[lalit-satapathy]

Can you also specify the Kibana version that you have?

It lets you update in 8.7.0-SNAPSHOT, May be its newly added.

[rajvi-patel-22]

It lets you update in 8.7.0-SNAPSHOT, May be its newly added.

Yes @lalit-satapathy. It could be the case. Because I tried to add description in 8.3.0 and 8.6.1 but I didn't get the option.

[agithomas]

@rajvi-elastic , as the PR is already merged, we have two options here considering the description is no longer available in the kibana dashboard

Option 1: Do a rollback
Option 2: Create a PR with say 8.7 as the version having the panel description.

The decision will soon be shared here. However, please work on the option 2 and share the issue & PR link here.

[agithomas]

We also need to find out how much dashboards under various integration has description in panels.

a. Identify the json block in vis that holds the description info of the panels.

b. Grep the visualisation json of all integrations having the block.

c. Do the dashboard screenshot validation additionally.

We need to have the names of dashboards with integration impacted by the above mentioned problem. How many among in this list had a lens migration completed. Please take this up at the highest priority.

@agithomas, We have looked into the other integrations but no any other integrations are having the panel description apart from the Redis Enterprise.
