Important Information Regarding Google Workspace Event Lag Times
- As per Google’s documentation, Google Workspace administrators may observe lag times ranging from minutes up to 3 days between the time of an event’s occurrence and the event being visible in the Google Workspace admin/audit logs.
- This rule is configured to run every 10 minutes with a lookback time of 130 minutes.
- To reduce the risk of false negatives, consider reducing the interval that the Google Workspace (formerly G Suite) Filebeat module polls Google’s reporting API for new events.
-
By default,
var.intervalis set to 2 hours (2h). Consider changing this interval to a lower value, such as 10 minutes (10m). - See the following references for further information:

Setupedit
The Google Workspace Fleet integration, Filebeat module, or similarly structured data is required to be compatible with this rule.
