## TL;DR

Either wait for the alert to trigger again (the default repeat interval is one hour) or recreate the alert. Notifier changes take effect only after the next alert trigger.

## Fix

1. Either wait for the alert to trigger again (the default repeat interval is one hour) or recreate the alert.
   Expected: You get the expected result; the problem is gone.

## When to use

- You are setting up or using this Chronosphere feature.
- The symptom matches: notifier doesn't trigger after an alert fires.

## When NOT to use

- Unrelated Chronosphere issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Variant phrasings

### notifier doesn't trigger after an alert fires

## Why it happens

The alert fired but the notifier change you made didn't take effect. Notifications send after the alert triggers, so notifier edits apply from the next trigger.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
