You can export logs from the Nebius AI Cloud services you use.

Prerequisites

  1. Make sure that you are in a group that has at least the editor role within your tenant; for example, the default editors group. You can check this in the Administration → IAM section of the web console.
  2. Make sure that you have sufficient logging quotas.

How to export logs

  1. In the web console, go to https://mintcdn.com/nebius-ai-cloud/1Ha0sWR6e1mnIaHS/_assets/sidebar/observability.svg?fit=max&auto=format&n=1Ha0sWR6e1mnIaHS&q=85&s=911a6fc7da512bdf286067c68245a501 ObservabilityLogs.
  2. Use the period, resource or log level filters to find the logs to export. You can also use the LogQL query language to filter logs.
  3. Click https://mintcdn.com/nebius-ai-cloud/1Ha0sWR6e1mnIaHS/_assets/arrow-up-to-line.svg?fit=max&auto=format&n=1Ha0sWR6e1mnIaHS&q=85&s=5ed27f4ff211ee66d1ee185f2af2955e Export logs.
  4. In the window that opens:
    • Select a time range.
    • Select an existing bucket or create a new one to store the logs. To create a new one, see Bucket parameters.
    • Select a format:
  5. Click Export.
If the Object Storage quota is exceeded, the export fails with a timeout after 90 minutes.

How to view log exports

To see a list of all your log exports:
  1. In the web console, go to https://mintcdn.com/nebius-ai-cloud/1Ha0sWR6e1mnIaHS/_assets/sidebar/observability.svg?fit=max&auto=format&n=1Ha0sWR6e1mnIaHS&q=85&s=911a6fc7da512bdf286067c68245a501 ObservabilityLogsExports. This tab shows the following information for each export:
    • Operation ID: The unique identifier for the export operation. Use this ID to distinguish between exports stored in the same bucket.
    • Status: In progress, Finished or Canceled.
  2. Click https://mintcdn.com/nebius-ai-cloud/1Ha0sWR6e1mnIaHS/_assets/button-vellipsis.svg?fit=max&auto=format&n=1Ha0sWR6e1mnIaHS&q=85&s=e80b8e57c43bfd117679262e6a1334adView bucket next to an export. The exported logs are stored in the selected bucket with the following path structure:
    logs/<operation_ID>/<timestamp>/<segment_number>.<extension>
    
    Large exports may be split into segments and stored as separate files. The files are numbered sequentially starting from 0. In some cases, segments may be split further into parts, indicated by a dash (-) and the part number after the segment number.

How to cancel an export

You can cancel an export while its status is In progress. If an export has the status Finished, you can delete the exported logs instead. To cancel an export:
  1. On the Logs page, switch to the Exports tab.
  2. Next to the export that you want to cancel, click Cancel.
  3. In the window that opens, confirm the cancellation.
