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 table displays all annotations available in the organization along with the total number of displayed annotations. Table columns provide annotation details.

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
Created at	The time indicating when the annotation was added
Project	The name of the project holding the annotated SLO
Service	The name of the service holding the annotated SLO
Objective	The name of the annotated SLO objective

Not all columns are displayed by default; however, you can configure the table view.

The Events section provides the following options:

• 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
• Export annotations to CSV
• Customize the table

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

To preview the annotation, click its row:

Annotation preview

To export filtered annotations and to show, hide, and reorder table columns, click next to the time picker. Then select the required option:

• Export to CSV to download a CSV file with filtered annotations. The CSV contains all available columns, including hidden, sorted in the current order.
  Up to 10k entries
• Customize columns to view all available columns and handle their visibility in the table.

  

  Customizing the table

Table customization

The following table customization options are available:

• Show and hide columns—select the required columns in the list.
• Reorder the displayed columns—drag the required column and drop it into the desired position.
• Add custom columns—click + Add custom column, enter a header, and select the label key.
  • The column will display this key's values.
  • To delete a column, hover over it in the menu and click .

Adding a custom column

Custom column key points

• Prerequisite: SLOs in your organization must have annotations with the required labels.
• Functionality: Custom columns are populated with label values from annotations. The column will only display the values found in the annotations.
• Limitation: You can use only existing labels—it's not possible to create new labels while adding a custom column.
• Visibility: Custom columns are private and visible only to you.

Table filtering

To filter annotations, 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.

Filter	Description
Annotation type	Includes the User, Alert, and Data event types with their subtypes.
Project	Projects that contain annotated SLOs.
Service	Services that contain the annotated SLOs.
SLO	Specific annotated SLOs.
Labels	Labels added to SLOs and SLO annotations.
Author	Annotation author for the User annotation type. Contains user names and API keys

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
