Logs

The Logs tab provides the postgres_db_data_log PostgreSQL DB logs. Use these log files to troubleshoot issues. These logs are stored in the customer's cloud subscription and are only streamed to the Tessell console for viewing purposes. Tessell does not store or move these logs out of the customer's cloud accounts.

1. Choose an instance name from the dropdown list to view the logs of that instance, if there are multiple instances.
2. On the left side, view the log entries. Select a log file to view its details on the right side.
3. Click Go Live to view logs updated every 15 seconds. A Live status indicates you are viewing updated logs.
4. Use the search bar to look for specific log terms.
5. Toggle Show line numbers to view line numbers for all logs in the log file.
6. To view previous logs, use the Load previous logs button. To go to the last log line, use the Jump to bottom button.
7. Log files for the last hour are displayed by default. You can choose to view logs for 1, 3, 6, 12, or 24 hours.

Downloading logs

To download logs for a standard time range (1h, 3h, 6h, 12h, or 24h), select the download button. The log file downloads to your local machine in your Downloads folder.

To download logs for a custom date range (AWS subscriptions only):

1. Select Custom in the time range selector, choose your desired start and end date and time, and select Apply.
2. Select the download button. A download request dialog box opens.
3. Select an expiry duration for your exported file — 1, 2, 3, 7, or 30 days — or select No Expiry to retain the file indefinitely.
4. Select Submit to queue the export request.

   Note: The export is processed asynchronously. Depending on queue position and log volume, the download may not be immediately available.

5. To check the status of your export, go to the Download History section of the Logs tab. The following statuses are possible:

   Status	Description
   Queued	The export request is waiting to be processed. Only one export can run at a time per AWS account per region.
   In Progress	The export is being processed.
   Completed	The export is ready. Select Download to retrieve the file via a pre-signed URL.
   Failed	The export could not be completed. Retry or contact support.

6. After the export reaches Completed status, select Download to download the file.

   Note: The download link is valid for 1 hour. If the link expires before you download the file, go back to the Download History section and select Download again to generate a fresh link. The exported file remains available in storage until the expiry duration.

7. To delete an exported file before it expires, select Delete next to the completed export in the Download History section.

Notes:

• AWS only: Custom range log downloads using the export flow are supported for AWS subscriptions only. For non-AWS subscriptions, the existing download behavior applies.
• Feature enablement: The DB log export feature must be enabled for your AWS subscription. For new AWS subscriptions, this is enabled by default. For existing subscriptions, contact your administrator to enable it.
• Queue behavior: Only one export can run at a time per AWS account per region. If another export is in progress for the same account and region, your request is queued and processed when the current export completes.
• Size limit: Export requests are limited to 5 GB of log data. Requests exceeding this limit are rejected at submission.
