Simple Log Service:Manage log storage space

Last Updated:Sep 04, 2025

After you enable the log analysis feature, Cloud Firewall allocates log storage space based on the storage capacity that you specify. This topic describes how to manage log storage space in the Cloud Firewall console. You can view, increase, and clear log storage space that you purchase.

Prerequisites

The log analysis feature of Cloud Firewall is enabled. For more information, see Enable the log analysis feature.

Manage log storage capacity

No limits are imposed on log storage capacity for Cloud Firewall that uses the pay-as-you-go billing method.

If the log storage capacity is exhausted, new logs cannot be written to the dedicated Logstore and the log data is incomplete. To avoid this issue, we recommend that you monitor the usage of log storage on a regular basis.

  1. Log on to the Cloud Firewall console.

  2. In the left-side navigation pane, choose Log Monitoring > Log Analysis.

  3. In the upper-right corner of the Logs tab, view the log storage usage.

    The log storage usage that is displayed is not updated in real time and is delayed for 2 hours. We recommend that you increase the log storage capacity or delete logs to release the used storage before the capacity is exhausted.

  4. Optional. If the capacity is about to be exhausted, increase the log storage capacity or delete existing logs to release the used storage.

    Warning

    You cannot restore logs after the logs are deleted. Proceed with caution.

    • Increase the log storage capacity: In the upper-right corner of the Logs tab, click Upgrade Storage. On the page that appears, specify a larger log storage capacity and complete the payment.

      Note

      The fee for additional log storage capacity is USD 80 per 1,000 GB-month. The subscription duration of the log storage capacity varies based on the subscription duration of Cloud Firewall and cannot be modified.

    • Delete existing logs: In the upper-right corner of the Logs tab, click Delete All Logs. In the dialog box that appears, click OK. The deletion requires approximately 1 to 2 hours to complete.

      Note

      After you enable the log analysis feature, you can clear the log storage four times. Each time you renew Cloud Firewall, the quota to clear the log storage is reset to four times.
