Simple explanation
Once an alert's condition is met, something needs to actually happen — this lesson covers the available actions and how they're configured.
Technical explanation
- Common alert actions: send an email notification, run a script (allowing custom, arbitrary automated response), add the triggering event(s) to a lookup file, log the event, or trigger a webhook (notifying an external system).
- Multiple actions per alert — an alert can be configured with more than one action simultaneously (e.g., both emailing a team AND logging to a tracking lookup file).
- Trigger condition granularity: alerts can trigger based on the number of results, based on a specific field's value crossing a threshold (via custom eval-based conditions), or simply whenever any results are returned at all.
- Severity levels — many alert configurations support assigning a severity (informational, low, medium, high, critical), which can then be used to filter/prioritize in the alerts list or drive different response actions based on severity.
- Testing an alert before relying on it — running the underlying search manually first, confirming it returns the expected results under known conditions, is an important step before trusting a newly configured alert to fire correctly in production.

Concept Check
"An alert is configured to fire based on 'number of results > 0,' but the underlying search itself was never tested manually before enabling the alert." This isn't wrong configuration per se, but it's a risky operational practice — an alert should be tested manually first (running its search directly and confirming expected behavior under known conditions) before being trusted to run automatically and unattended, since an untested search could have a logic error that either never fires or fires constantly on false conditions.
Interview-style Q&A
Q: Why might an alert be configured with multiple actions rather than just one? A: "Different actions serve different purposes even for the same event. Email might notify the on-call team for immediate human awareness, while simultaneously logging the event to a lookup file builds a historical record for later trend analysis or reporting — the two aren't mutually exclusive, and combining them means the immediate notification need and the longer-term tracking need are both satisfied by the same alert configuration, rather than requiring two separate alerts watching the same condition."
Memory trick
"Fire the Action, once the Condition is True" — the basic if/then structure underlying every alert, regardless of which specific action or condition is configured.
