Simple Log Service:CloudLens for SLS

Last Updated:Jun 02, 2026

CloudLens for SLS helps you monitor and manage SLS assets such as projects and Logstores, improving management efficiency and resource consumption visibility.

Features

CloudLens for SLS provides the following capabilities.

  • Centrally manage projects and Logstores in your account that meet specific conditions. For more information about the conditions, see Limits.CloudLens for SLS

  • Enable one-click collection for instance logs (important logs, detailed logs, and job operational logs) and global logs (audit logs, billing logs, error logs, and monitoring metrics), and centrally manage collection status.

    Note

    Instance logs (important, detailed, and job operational) and global logs (audit, error, and monitoring metrics) are viewable only after you enable log collection.

    • Important logs: Consumer group consumption delay logs at the Logstore level, plus Logtail error, heartbeat, and statistics logs. Stored in the internal-diagnostic_log Logstore of a specified project.

    • Detailed logs: Operation logs for creating, modifying, updating, and deleting assets within a project, plus data read/write logs. Stored in the internal-operation_log Logstore of a specified project.

    • Job operational logs: Error and latency data for data import (new version), scheduled SQL, and data shipping (new version) tasks. Stored in the internal-diagnostic_log Logstore of a specified project.

    • Audit logs: Operation logs for creating, modifying, updating, and deleting resources across all projects in your account. Stored in the internal-audit_log Logstore of a specified project.

    • Billing logs: SLS billing data collected through Cost Manager, stored in Tablestore (OTS) and updated daily. Description of billing data.

      Note
      • Initial data import takes 1-2 hours, depending on billing data volume.

      • Only public cloud users can enable billing logs.

      • Once enabled, this feature cannot be disabled.

    • Error logs: Errors from resource operations (create, modify, update, delete) and data read/write across all projects in your account. Stored in the internal-error_log Logstore of a specified project.

    • Monitoring metrics: Traffic, request, and latency metrics at the project and Logstore levels. Stored in the internal-monitor-metric MetricStore of a specified project.

    CloudLens for SLS

  • CloudLens for SLS provides preset alert rules (baseline alerts, period-over-period comparisons) for resources such as projects, Logtail, and consumer groups. Notifications support text messages, DingTalk, email, voice calls, and custom webhooks. Set alerts.Alerts

  • Visual reports span eight categories: Overview, Access Monitoring, Collection Monitoring, Operation Monitoring, Job Monitoring, Quota Monitoring, SQL Quality Monitoring, and Billable Resource Monitoring. View data reports.CloudLens for SLS

  • View quota information for eligible projects and Logstores in your account. For more information about the conditions, see Limits.

Scenarios

  • Development and operations

    Monitor and manage SLS assets such as projects and Logstores. Query and analyze detailed logs, important logs, and job monitoring logs to troubleshoot issues faster.

  • IT O&M

    Detect and respond to anomalies in project service status, traffic, quotas, and Logtail metrics through built-in alerting.

  • Security audit

    Audit logs record resource operations (create, update, delete) within projects, enabling security analysis over specific time frames.

Asset details

  • Project, Logstore, and MetricStore

    • When you enable important log and job operational log collection, SLS creates an internal-diagnostic_log Logstore in your selected project.

    • When you enable detailed log collection, SLS creates an internal-operation_log Logstore in your selected project.

    • When you enable audit log collection, SLS creates an internal-audit_log Logstore in your selected project.

    • When you enable error log collection, SLS creates an internal-error_log Logstore in your selected project.

    • When you enable monitoring metric collection, SLS creates an internal-monitor-metric MetricStore in your selected project.

Notes

Warning

The CloudLens feature requires at least one project to exist under your Alibaba Cloud account.

When you enable and use the CloudLens feature, Simple Log Service checks whether a project exists under your account based on the following logic.

Detection logic

  1. When you enable the CloudLens feature for the first time, Simple Log Service checks whether a project exists under your Alibaba Cloud account. If no project exists, a project named aliyun-product-data-Alibaba Cloud account ID-cn-heyuan is created in the China (Heyuan) region.

  2. After you enable the CloudLens feature and navigate to the CloudLens page, Simple Log Service checks only whether a project exists under your Alibaba Cloud account. It does not automatically create a project in the China (Heyuan) region. You can manually create a project. For more information about how to create a project, see Manage projects.

Delete a project

  • To delete the aliyun-product-data-Alibaba Cloud account ID-cn-heyuan project, open Cloud Shell and run the following command. Replace Alibaba Cloud account ID with your actual account ID.

    aliyunlog log delete_project --project_name=aliyun-product-data-Alibaba Cloud account ID-cn-heyuan --region-endpoint=cn-heyuan.log.aliyuncs.com
  • For more information about how to delete other projects and Logstores, see Manage Logstores and Manage projects.
