What are two intervals when Tableau Server verifies if data conditions for data-driven alerts are...

Data-driven alerts notify users when data meets conditions (e.g., sales > $10K). Let’s examine when Tableau checks these:

Alert Mechanics:

Enabled per site (Settings > General > Data-Driven Alerts).

Backgrounder evaluates conditions against extract data.

Check Intervals: Configurable via tsm configuration set -k dataAlerts.checkIntervalInMinutes (default: 60 minutes).

Refresh Trigger: Also checks post-extract refresh for immediate updates.

Option A (Every 60 minutes): Correct.

Details: Default interval—Backgrounder polls every hour to evaluate alert conditions.

Config: Adjustable (e.g., -v 30 for 30 minutes).

Option D (Whenever extracts in the related workbook are refreshed): Correct.

Details: An extract refresh updates the data, triggering an immediate alert check to catch changes promptly.

Why: Ensures timely notifications without waiting for the next poll.

Option B (Every 10 minutes): Incorrect.

Why: Not the default—possible via config, but not standard.

Option C (Whenever a new extract is published): Incorrect.

Why: Publishing creates the extract; alerts trigger on refreshes or polling, not initial publication.

Why This Matters: Timing affects alert responsiveness—balancing frequency and server load is key.
