Gmail log events

Security investigation tool

Supported editions for the Gmail log events data source in the investigation tool:
Enterprise Plus, Education Plus

As your organization's administrator, you can use the security investigation tool to run searches related to Gmail log events, and to take action based on search results. From the investigation tool, you can view a record of actions to see your organization's user and admin activity in Gmail—for example, when emails are classified as spam, released from quarantine, or sent to admin quarantine. If you have the appropriate privileges in the investigation tool, you can also view the content of a Gmail message as part of an investigation.

You can also conduct a search based on Gmail log events, and then use the investigation tool to take action—for example, to delete specific messages, mark messages as spam or phishing, send messages to quarantine, or send messages to users' inboxes.

Your access to the security investigation tool

  • The security investigation tool requires a premium Google Workspace edition (Enterprise Plus, Enterprise Standard, or Education Plus).
  • You can access logs using the Chrome browser for the Google apps you have installed. For example, Gmail.
  • Your ability to run a search in the investigation tool depends on your Google edition, your administrative privileges, and the data source. If you're unable to run a search in the investigation tool for a specific data source, you can use the audit and investigation page instead. 
  • You can run a search in the investigation tool on all users, regardless of the Google edition they have.
