Add Annotations

Overview

The annotation system overlays log events onto chart timelines, enabling visual correlation between data patterns and discrete events.

Understand How Annotations Work

When annotations are configured, a secondary timeline appears at the top of the chart. Each mark on this timeline represents a log event. Hovering over a mark reveals the event details.

This allows you to correlate observable spikes or anomalies in the chart data with specific events, such as a container restart or a deployment.

Add an Annotation to a Panel

To add an annotation to a panel:

1. Click the + (plus) button used to add queries within the panel editor.
2. The resulting menu offers two options: Add a Query or Add an Annotation.
3. Select Add an Annotation and configure the log event filter.

Annotations are currently available for log events. This feature is comparable to the event overlay available in the Trace Explore view.
