The Events section provides a centralized view of all annotations added to SLOs across your organization. It facilitates visibility into key events or changes that impact your system performance for better monitoring and tracking meaningful updates such as budget adjustments, alerts, or key milestones.

When an annotation is added to an SLO, it automatically appears in the Events > Annotations table.

Events section

The available columns are listed in the table.

Column header	Description
Applied from	The beginning of the annotated period
Applied to	The end of the annotated period
Created by	Annotation origin: system or user-created
SLO name	The name of the annotated SLO
Description	The annotation body

Project	The name of the project holding the annotated SLO

The following options are available:

• Search annotations by keywords in annotation descriptions
• Filter annotations
• Shift the time window to display annotations with an annotated period falling within the selected time frame
• Preview annotations

Accessing Events

To access Events, select Events in the main navigation menu:

Accessing the event list

The table with annotations opens. By default, it displays annotations as follows:

• Sorted by the annotated period start date, in the descending order
• The Last month time window
  Annotations with the annotated period ending within the last month are displayed

You can show, hide, and reorder columns in the table to configure your required view. To configure the table view, select the desired columns in the table customization menu next to the time picker:

Table filtering

You can filter annotations displayed in the table by the following parameters:

• Annotation type—alert, budget adjustment, user
• Project
• SLO
• User

For this, click Show filters under the section header:

Opening the filter controls

The filter controls open. Select the required filters to apply them to the table.

Key points for annotation filtering:

• Next to each filter option, the total number of available annotations is displayed.
• Filters are interconnected. Selecting a filter dynamically adjusts the available choices in other categories.

Applying a filter narrows down the available filters in other categories.
Since the Alert annotation type is system-added, the Users list is empty. The number of annotations per project is also reduced
