To make this compatible with kb-dashboard 0.4.0 (released 3/17), run the automated upgrade and recompile:

# 1. Upgrade YAML files in-place (handles all schema renames automatically)
uvx kb-dashboard-cli upgrade --write --input-dir packages/<PACKAGE>/_dev/shared/kibana

# 2. Recompile
uvx kb-dashboard-cli compile \
  --input-dir packages/<PACKAGE>/_dev/shared/kibana \
  --output-dir packages/<PACKAGE>/kibana/dashboard \
  --format json

The upgrade command automatically handles:

• dimensions → breakdowns (pie, treemap, datatable)
• dimension → breakdown (waffle)
• dimensions_by → metrics_split_by (datatable)
• titles_and_text → appearance fields (pie, mosaic, waffle, XY)
• legend.size → legend.width
• appearance.shape camelCase → snake_case (gauge)
• color.stops → color.thresholds with stop → up_to (gauge)
• Static numeric minimum/maximum/goal → EVAL expressions (ESQL gauge)

Review the diff after upgrading to confirm the changes look correct, then recompile and commit.

Upgrade and post-upgrade compile succeeded with 0.4.0.
Please apply these commands in your branch and commit both YAML + regenerated JSON artifacts.

Suggested commands:

• The percent calculation in some queries is OK, in some is off by *100 (see comments)
• I am not sure that SUM(RATE(cumulative_field)) becomes rate of field (see comments)
• The OTel config example doesn't include resource processor to add data stream name of etcd.otel which is used in the assets
• Alerting rule templates have ratio calculations (division), please make confirm that those are not integer divisions

@stefans-elastic -
Can you check the overview dashboard panels below?

1. Has Leader by Instance. Should this be Leader by Instance? Also if we represent the count then the panel should be updated to display exact number format values.
2. Leader Changes Seen. Should this be Leader Changes?

[muthu-mps]

Can you confirm whether we are able to install an Alerting Rule in 9.2.1 stack version? This is to make sure that everything works fine with the minimum supported stack version.

yes, I was able to install an Alerting Rule in 9.2.1.

• "Has Leader by Instance" → Renamed to "Leader by Instance" and updated the metric label from "Has Leader" to "Leader".
  I kept decimals: 1 for the number format — with decimals: 0 Kibana renders duplicate tick labels on the Y-axis (multiple fractional ticks round to the same integer). Since the axis is bounded to 0–1, the values display as 0.0 and 1.0 which are still unambiguous.
• "Leader Changes Seen (cumulative)" → Renamed to "Leader Changes Seen", dropping the "(cumulative)" suffix since the query actually computes a rate (SUM(RATE(...))), not a cumulative value. Kept "Seen" to stay consistent with the underlying metric name etcd_server_leader_changes_seen_total.
