- Example Request
- Example Response

Retrieves a compressed (.gz) log file that contains a range of log messages for a particular host in an Atlas cluster.

Process and audit logs are updated from the cluster backend infrastructure every five minutes and contain log data from the previous five minutes. If you are polling the API for log files, polling every five minutes is recommended.

Example

If the logs are updated at 4:00 UTC and then you poll the API, the API returns log data from the interval between 3:55 UTC and 4:00 UTC.

Feature unavailable in Free and Shared-Tier Clusters

This feature is not available for M0 (Free Tier), M2, and M5 clusters. To learn more about which features are unavailable, see Atlas M0 (Free Tier), M2, and M5 Limitations.

Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

Important

You must have the Project Data Access Read Only role or higher in the project that the cluster belongs to in order to retrieve the log.
