Configure Cluster-Wide Defaults

The Global query priorities page is where Admin users set the cluster-wide defaults that apply when an individual user, team, or service account hasn’t configured its own value. These defaults also drive the Scheduled class — the priority and timeout used for Grafana alert evaluation, the rule manager, and scheduled views.

Page Layout

Each class block follows the same shape:

1. Class header — Scheduled, Interactive, or Machine. The class identifies what kind of traffic these settings apply to.

2. Priority (all streams) — the wildcard priority. Applied to every stream that doesn’t have its own per-stream override below.

3. Timeout (all streams) — the wildcard timeout, in seconds. Applied to every stream that doesn’t have its own override.

4. Effective column — what the resolution chain produced for the wildcard row given the current configuration.

5. Source column — which level of the chain produced the effective value (class default (*) for the wildcard you just set, or another label if a more specific entry won).

6. Per-stream overrides disclosure — expand to add a stream-specific row that overrides the wildcard.

7. Save / Cancel buttons appear at the top right of the block once you have unsaved edits.

Set the Wildcard Default for a Class

The wildcard rows govern every stream that doesn’t have its own per-stream entry. In most clusters, the wildcard rows are the only thing you need to configure.

1. On the Global query priorities page, locate the class block you want to change ( Interactive or Machine; for Scheduled, see the section on configuring that).
2. In the Priority (all streams) drop-down, pick High, Medium, or Low (or (unset / use default) to clear).
3. In the Timeout (all streams) field, enter the timeout in seconds (or leave blank to clear).
4. The Effective and Source columns update live to show what the resolution chain will produce.
5. Click Save at the top right of the class block.

Add a Per-Stream Override

Per-stream overrides let you tune individual telemetry streams independently from the wildcard.

1. Expand the Per-stream overrides disclosure for the class.
2. Click + Add per-stream override and pick a stream from the drop-down ( APM, Events, Logs, Metrics, or RUM).
3. The new row appears with default Medium priority. Adjust the Priority and Timeout fields for the stream.
4. The Effective and Source columns on this row should update to show the new stream-specific values.
5. Click Save at the top right of the class block.

Configure the Scheduled Class

The Scheduled class block controls every alert evaluation, in-process rule manager query, and scheduled-view refresh in the cluster. We recommend keeping the Scheduled priority at High so alerts aren’t starved by interactive traffic.

Remove a Per-Stream Override

1. Expand the Per-stream overrides disclosure.
2. Click the (×) icon on the row you want to remove.
3. Click Save at the top right of the class block.

After removal, the stream falls back to the wildcard row.
