Simple Log Service:Usage notes

Last Updated:Aug 04, 2023

Simple Log Service and Apsara File Storage NAS (NAS) jointly launch the log analysis feature. You can use the feature to collect NAS access logs in real time. You can also query, analyze, transform, and consume the collected logs. This topic describes the assets, billing, and limits of the log analysis feature.

Assets

  • Dedicated project and Logstore

    After you enable the log analysis feature, Simple Log Service creates a project named nas-Alibaba Cloud account ID-Region ID in the region where your NAS file system resides and a dedicated Logstore in the project.

    • If the file system uses Network File System (NFS), the Logstore is named nas-nfs.

    • If the file system uses Server Message Block (SMB), the Logstore is named nas-smb-access-log.

    Important
    • Do not delete the project or Logstore that is related to NAS logs. Otherwise, NAS logs cannot be sent to Simple Log Service.

    • If you have enabled the pay-by-ingested-data billing mode, Simple Log Service creates a dedicated Logstore that uses the pay-by-ingested-data billing mode by default. If you want to switch the billing mode from pay-by-ingested-data to pay-by-feature, you can modify the configuration of the Logstore. For more information, see Modify the configurations of a Logstore.

  • Dedicated dashboards

    After you enable the log analysis feature, Simple Log Service automatically creates dashboards. The following table describes the dashboards.

    Note

    We recommend that you do not make changes to the dedicated dashboards because the dashboards may be upgraded or updated at any time. You can create a custom dashboard to visualize log analysis results. For more information, see Create a dashboard.

The fees are included in the bills of Simple Log Service. For more information, see Billable items of pay-by-feature.
