Code Review
This pull request aims to resolve layout conflicts in the TiCDC Grafana dashboards by adjusting panel IDs and coordinates. Additionally, it introduces a new script, check-ticdc-dashboard.sh, to automate the detection of duplicate panel IDs and overlapping panels, which is a great initiative to maintain dashboard quality.
My review focuses on the new script. While it's a valuable addition, I've identified a couple of areas for improvement to make it more robust and reusable. Specifically, the script currently checks a hardcoded file path, and the logic for detecting overlapping panels is not comprehensive. My suggestions aim to address these points to ensure the script is effective for all dashboards.

1114-26015: Consider enhancing the PR description.The PR description contains only template placeholders without specific details about:
- Which panels had duplicate IDs or layout conflicts
- How the new ID ranges (62002-62005) were chosen
- What testing was performed to verify the fixes
- The specific issue number being addressed
While not a code issue, adding these details would improve traceability and make it easier for reviewers to verify that the changes fully address the layout conflicts mentioned in the PR title.

- Line 1114: The dashboard JSON still contains duplicate panel "id" values
(notably 22476, 3, and 60007) even though you added unique new IDs
(62002–62005); locate every panel object with an "id" field (search for "id":
22476, "id": 3, and "id": 60007) and reassign each duplicated panel a globally
unique integer ID that does not collide with existing IDs (including the newly
added 62002–62005), updating any internal references if present so all panels
have unique "id" values and the layout conflicts are fully resolved.
In `@metrics/nextgengrafana/ticdc_new_arch_next_gen.json`:
- Around line 20177-20179: The dashboard JSON contains duplicate panel IDs
(notably id 22476 used in the panel object referenced by
root.panels[11].panels[19] and again as root.panels[20], and id 60007 used in
root.panels[9].panels[23] and root.panels[18]); to fix, assign new unique
numeric IDs for the duplicated panel objects (e.g., replace one instance of
22476 and one instance of 60007 with freshly generated IDs that do not exist
elsewhere in the document) and update any internal references to those panel IDs
(for example in dashboard links, repeats, or panelTarget references) to the new
values so no two panels share the same id property (verify uniqueness across
root.panels and nested panels after changes).
In `@scripts/check-ticdc-dashboard.sh`:
- Around line 20-25: The duplicate-ID detection uses the jq expression assigned
to dup which only inspects nested panels (.panels[] | .panels[]?) and thus
misses top-level panels/rows; update the jq expression (the one building dup and
the separate jq that computes max id) to collect both nested panels and
top-level panel objects (so top-level entries are treated the same as .panels[]
items) before grouping by .id and computing max, ensuring the dup variable and
the max-ID query operate over the same complete set of panels for
"$dashboard_file".

- Line 9869: Update the PR description and release notes to explicitly document
the change to the dashboard refresh interval: the JSON key "refresh" in
ticdc_new_arch_with_keyspace_name.json was changed to "10s", which increases
dashboard responsiveness but also raises query/load on the metrics backend;
mention the reason this change was made (e.g., UX/layout fix), the expected
impact on query load, and any recommended migration or rollback guidance so
reviewers and operators understand the behavioral change.
