Kibana Kibana 'Watcher' not triggering alerts

Incorrect watcher configuration or data conditions not met.

Understanding Kibana and Its Watcher Feature

Kibana is a powerful visualization tool that works with Elasticsearch to provide insights into your data. One of its key features is the 'Watcher', which allows users to set up alerts based on specific conditions in their data. This can be crucial for monitoring and responding to critical events in real-time.

Identifying the Symptom: Watcher Not Triggering Alerts

One common issue users encounter is when the Kibana Watcher does not trigger alerts as expected. This can be frustrating, especially when you rely on these alerts to monitor important metrics or events.

What You Might Observe

You may notice that despite setting up a watcher, no alerts are being sent or logged. This can occur even when the conditions you believe should trigger the alert are met.

Exploring the Issue: Why Watcher Fails to Trigger

The primary reason for this issue is often an incorrect configuration of the watcher or the conditions for triggering the alert are not being met. This can happen due to a variety of reasons, including logical errors in the conditions or misconfigured thresholds.

Common Misconfigurations

  • Incorrect indices or fields specified in the watcher query.
  • Logical errors in the condition script.
  • Thresholds set too high or too low, causing the condition to never be met.

Steps to Resolve the Watcher Issue

To resolve the issue of Kibana Watcher not triggering alerts, follow these steps:

Step 1: Review Watcher Configuration

Start by reviewing the configuration of your watcher. Ensure that the indices and fields specified in the query are correct. You can do this by navigating to the Kibana Watcher UI and checking the details of your watcher.

Step 2: Validate the Condition Script

Check the condition script for any logical errors. Make sure that the script accurately reflects the conditions under which you want the alert to trigger. You can test the script using the Elasticsearch scripting API.

Step 3: Adjust Thresholds

If your watcher uses thresholds, ensure they are set appropriately. You may need to adjust these thresholds based on the data patterns you observe. Consider using the range query to test different threshold levels.

Conclusion

By carefully reviewing and adjusting your watcher configuration, condition scripts, and thresholds, you can resolve issues with Kibana Watcher not triggering alerts. For more detailed guidance, refer to the Kibana Alerting Documentation.
