Audit Events (PREMIUM)

GitLab offers a way to view the changes made within the GitLab server for owners and administrators on a paid plan.

GitLab system administrators can also take advantage of the logs located on the file system. See the logs system documentation for more details.

You can generate an Audit report of audit events.

Overview

Audit Events is a tool for GitLab owners and administrators to track important events such as who performed certain actions and the time they happened. For example, these actions could be a change to a user permission level, who added a new user, or who removed a user.

Use cases

• Check who changed the permission level of a particular user for a GitLab project.
• Track which users have access to a certain group of projects in GitLab, and who gave them that permission level.

List of events

There are two kinds of events logged:

• Events scoped to the group or project, used by group and project managers to look up who made a change.
• Instance events scoped to the whole GitLab instance, used by your Compliance team to perform formal audits.

Impersonation data

Introduced in GitLab Premium 13.0.

When a user is being impersonated, their actions are logged as audit events as usual, with two additional details:

1. Usual audit events include information about the impersonating administrator. These are visible in their respective Audit Event pages depending on their type (Group/Project/User).
2. Extra audit events are recorded for the start and stop of the administrator's impersonation session. These are visible in the instance Audit Events.

Group events (PREMIUM)

A user with:

• Owner role (or above) can retrieve group audit events of all users.
• Developer or Maintainer role is limited to group audit events based on their individual actions.

Group events do not include project audit events.

To view a group's audit events:

1. Go to the group.
2. On the left sidebar, select Security & Compliance > Audit Events.

From there, you can see the following actions:

• Group name or path changed.
• Group repository size limit changed.
• Group created or deleted.
• Group changed visibility.
• User was added to group and with which permissions.
• User sign-in via Group SAML.
• Permissions changes of a user assigned to a group.
• Removed user from group.
• Project repository imported into group.
• Project shared with group and with which permissions.
• Removal of a previously shared group with a project.
• LFS enabled or disabled.
• Shared runners minutes limit changed.
• Membership lock enabled or disabled.
• Request access enabled or disabled.
• 2FA enforcement or grace period changed.
• Roles allowed to create project changed.
• Group CI/CD variable added, removed, or protected status changed. Introduced in GitLab 13.3.

Group events can also be accessed via the Group Audit Events API

Project events (PREMIUM)

A user with a Maintainer role (or above) can retrieve project audit events of all users. A user with a Developer role is limited to project audit events based on their individual actions.

Project event queries are limited to a maximum of 30 days.

Instance events (PREMIUM SELF)

Introduced in GitLab Premium 9.3.

Server-wide audit events introduce the ability to observe user actions across the entire instance of your GitLab server, making it easy to understand who changed what and when for audit purposes.

Instance events do not include group or project audit events.

To view the server-wide audit events:

1. On the top bar, select Menu > {admin} Admin.
2. On the left sidebar, select Monitoring > Audit Events.

The following user actions are recorded:

• Sign-in events and the authentication type (such as standard, LDAP, or OmniAuth)
• Failed sign-ins
• Added SSH key
• Added or removed email
• Changed password
• Ask for password reset
• Grant OAuth access
• Started or stopped user impersonation
• Changed username (introduced in GitLab 12.8)
• User was deleted (introduced in GitLab 12.8)
• User was added (introduced in GitLab 12.8)
• User requests access to an instance (introduced in GitLab 13.9)
• User was approved via Admin Area (introduced in GitLab 13.6)

Sign-in events (FREE)

Successful sign-in events are the only Audit Events available at all tiers. To see successful sign-in events:

1. Select your avatar.
2. Select Edit profile > Authentication log.

After upgrading from GitLab Free to a paid tier, successful sign-in events are the only Audit Events visible in Audit Events views until more events are logged.

Missing events

Some events are not tracked in Audit Events. See the following epics for more detail on which events are not being tracked, and our progress on adding these events into GitLab:

• Project settings and activity
• Group settings and activity
• Instance-level settings and activity

Don't see the event you want in any of the epics linked above? You can use the Audit Event Proposal issue template to create an issue to request it, or you can add it yourself.

Disabled events

Repository push

The current architecture of audit events is not prepared to receive a very high amount of records. It may make the user interface for your project or audit events very busy, and the disk space consumed by the audit_events PostgreSQL table may increase considerably. It's disabled by default to prevent performance degradations on GitLab instances with very high Git write traffic.

If you still wish to enable Repository push events in your instance, follow the steps below.

In Omnibus installations:

1. Enter the Rails console:

   sudo gitlab-rails console
   

2. Flip the switch and enable the feature flag:

   Feature.enable(:repository_push_audit_event)
   

Search

The search filters you can see depends on which audit level you are at.

Filter	Available options
Scope (Project level)	A specific user who performed the action.
Scope (Group level)	A specific user (in a group) who performed the action.
Scope (Instance level)	A specific group, project, or user that the action was scoped to.
Date range	Either via the date range buttons or pickers (maximum range of 31 days). Default is from the first day of the month to today's date.

Export to CSV (PREMIUM SELF)

• Introduced in GitLab Premium 13.4.
• Feature flag removed in GitLab Premium 13.7.

Export to CSV allows customers to export the current filter view of your audit events as a CSV file, which stores tabular data in plain text. The data provides a comprehensive view with respect to audit events.

To export the Audit Events to CSV:

1. On the top bar, select Menu > {admin} Admin.
2. On the left sidebar, select Monitoring > Audit Events.
3. Select the available search filters.
4. Select Export as CSV.

Sort

Exported events are always sorted by created_at in ascending order.

Format

Data is encoded with a comma as the column delimiter, with " used to quote fields if needed, and newlines to separate rows. The first row contains the headers, which are listed in the following table along with a description of the values:

Column	Description
ID	Audit event id
Author ID	ID of the author
Author Name	Full name of the author
Entity ID	ID of the scope
Entity Type	Type of the scope (Project/Group/User)
Entity Path	Path of the scope
Target ID	ID of the target
Target Type	Type of the target
Target Details	Details of the target
Action	Description of the action
IP Address	IP address of the author who performed the action
Created At (UTC)	Formatted as YYYY-MM-DD HH:MM:SS

Limitation

The Audit Events CSV file is limited to a maximum of 100,000 events. The remaining records are truncated when this limit is reached.
