File Storage NAS:Log analysis based on SLS

Assets

• Dedicated project and Logstore

  When you enable the log analysis feature, SLS creates a project named nas-Alibaba Cloud account ID-Region ID in the region of your NAS file system and a dedicated Logstore in the project.

  • General-purpose NAS file system

    • 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.

  • Extreme NAS file system

    The Logstore is named nas-extreme-nfs.

  Important

  • Do not delete the project or Logstore used for NAS logs. Otherwise, NAS logs cannot be sent to SLS.

  • If you have enabled the pay-by-ingested-data billing mode, SLS automatically creates a dedicated Logstore that uses pay-by-ingested-data. To switch to pay-by-feature, modify the Logstore configurations. For more information, see Modify Logstore configuration.

• Dedicated dashboards

  When you enable the log analysis feature, SLS automatically creates the following dashboards.

  Note

  • Only General-purpose NAS file systems support dedicated dashboards. Do not modify the dedicated dashboards because they may be upgraded or updated at any time.

  • You can create a custom dashboard to visualize query results. For more information, see Create a dashboard.

  Protocol type	Dashboard	Description
  NFS	nas-nfs-nas_summary_dashboard_cn	Shows the overall NAS status, including the number of recently accessed volumes, the number of recent clients, total write traffic, and total read traffic.
  	nas-nfs-nas_audit_dashboard_cn	Shows operations on NAS file systems, including the number of create operations, deleted files, and read files.
  	nas-nfs-nas_detail_dashboard_cn	Shows NAS file system details, including the number of recently accessed files and operation trends.
  SMB	nas-smb-nas_audit_dashboard	Shows file events on NAS file systems, including files that are recently created, deleted, read, and written.

Billing

• If your Logstore uses the pay-by-feature billing mode, you are charged for storage, read traffic, requests, data transformation, and data shipping after NAS logs are collected to SLS. These fees are included in your SLS bill. For more information, see Pay-by-feature billable items.

• If your Logstore uses the pay-by-ingested-data billing mode, you are charged for ingested raw data after NAS logs are collected to SLS. These fees are included in your SLS bill. For more information, see Billable items for the pay-by-ingested-data model.

Limits

Only NAS access logs can be written to the dedicated Logstore. No limits apply to the query, analysis, and alerting features.
