tidb-cloud: add New Relic dashboards for Premium and Essential

[Yujie-Xie]

What is changed, added or deleted? (Required)

Add New Relic dashboard JSON templates under tidb-cloud/ for TiDB Cloud Premium, Essential, and Essential v2 (instances created on or after July 1, 2026). Follow the dashboard asset naming and placement used in #22662.

The three templates are copied byte-for-byte from artifacts/dashboard/newrelic/ in tidbcloud/metrics-integration at commit 7ccec7a2731a5709d3d1802ee26a2a4957065a4b. New Relic account IDs remain empty for users to configure during import.

Validation: parsed all three files with Python's JSON parser, verified SHA-256 equality with the source files, confirmed all accountIds fields are empty, and ran git diff --cached --check. This is an asset-only change; no application code or documentation prose changes.

Which TiDB version(s) do your changes apply to? (Required)

Tips for choosing the affected version(s):

By default, CHOOSE MASTER ONLY so your changes will be applied to the next TiDB major or minor releases. If your PR involves a product feature behavior change or a compatibility change, CHOOSE THE AFFECTED RELEASE BRANCH(ES) AND MASTER.

For details, see tips for choosing the affected versions.

• master (the latest development version)
• v8.5 (TiDB 8.5 versions)
• v8.4 (TiDB 8.4 versions)
• v8.3 (TiDB 8.3 versions)
• v8.2 (TiDB 8.2 versions)
• v8.1 (TiDB 8.1 versions)
• v7.5 (TiDB 7.5 versions)
• v7.1 (TiDB 7.1 versions)
• v6.5 (TiDB 6.5 versions)

Summary by CodeRabbit

• New Features
  • Added New Relic dashboards for TiDB Cloud Essential and Premium instances, with views of performance, storage, connections, commands and transactions, and resource-unit usage.
  • Added filters for instance name and ID. Dashboards also include changefeed metrics where available; those panels remain empty when CDC is not enabled.

Hi @Yujie-Xie. Thanks for your PR.

I'm waiting for a pingcap member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Before / after behavior

• observed — Modified behavior in tidb-cloud/monitor-new-relic-integration-tidb-cloud-dynamic-tracker-essential-v2.json: Adds the TiDB Cloud Essential dynamic tracker dashboard, including its Overview page, metric panels and NRQL queries, markdown section headings, and instance_name and instance_id variables. The variables default to * and query available values from tidb_cloud.% metrics. Panels cover database time, query throughput and duration, failures, storage, connections, SQL commands, plan-cache queries, transactions, request units, and CDC changefeed lag and status.
• observed — Modified behavior in tidb-cloud/monitor-new-relic-integration-tidb-cloud-dynamic-tracker-essential.json: Adds the public dashboard metadata and introductory markdown panels, identifying the dashboard as an Essential-instance overview and excluding Dedicated-only node, DM, and CDC metrics.
• observed — Modified behavior in tidb-cloud/monitor-new-relic-integration-tidb-cloud-dynamic-tracker-essential.json: Adds performance and storage panels for database time, queries per second, average query duration, failed queries, and row and columnar storage. The panels use 24-hour time series filtered by the instance variables; performance panels include configured SQL-type or operation-type breakdowns, and storage panels report bytes.
• observed — Modified behavior in tidb-cloud/monitor-new-relic-integration-tidb-cloud-dynamic-tracker-essential.json: Adds a Connections section with time-series panels for total and active connections and disconnections. The disconnection panel breaks results down by result; all three filter on the instance variables.
