Simple Log Service:Usage notes

The CloudLens for CLB application automatically aggregates real-time access logs and provides features such as intelligent inspection and real-time alerting.

• The application allows you to manage all CLB instances within your Alibaba Cloud account in a centralized manner.

• The application allows you to enable the log collection feature for instance logs and global logs with a few clicks and manage the log collection status in a centralized manner. Instance logs are access logs, and global logs consist of Cloud Config logs and CloudMonitor events. For more information, see Enable the data collection feature.

  • Access logs record detailed information about all requests that are sent to CLB instances. The information includes the time when the request is initiated, client IP address, latency, request path, and response from the server.

  • Cloud Config logs consist of change logs and resource non-compliance logs of Cloud Config.

  • CloudMonitor events are the events that are related to SLB certificate expiration.

  

• The application allows you to store, query, and analyze CLB access logs in real time.

• The application provides various reports, including Monitoring Center and Instance Inspection. You can subscribe to these reports and configure settings to send the reports by using emails or DingTalk group messages.

• The application supports custom alert settings and can send alert notifications by using the following methods: Message Center, text messages, emails, voice calls, DingTalk, and custom webhooks.

• The application extracts various metrics in real time based on raw access logs. The metrics include page views (PVs), request success rates, average latency, P50 latency, P99 latency, and inbound and outbound traffic. The application can extract metrics from one or more of the following dimensions: slbid, host, method, and status.

• The application provides the intelligent inspection feature and supports global inspection and slbid-based inspection. You can label anomalies in reports.

You can view the assets of the CloudLens for CLB application in the project that you specify. The following assets are included:

• Logstore

  • The Logstore that is used to store CLB access logs. You can use a custom Logstore.

  • The Logstore that is used to store Cloud Config logs. You can use a custom Logstore.

  • The Logstore that is used to store CloudMonitor events. You can use a custom Logstore.

  • The Logstore that is used to store inspection results. After you enable the log collection feature for access logs, Simple Log Service automatically generates a dedicated Logstore named Logstore for access logs-metrics-result.

  Warning

  • Do not delete the preceding Logstores. If you delete the preceding Logstores, related logs cannot be collected to Simple Log Service.

  • Do not delete the indexes of specific fields in the Logstore that is used to store CLB access logs. If you delete the indexes, metric conversion fails.

• Metricstore

  The Metricstore is used to store the metrics that are generated after raw metrics are aggregated. After you enable the log collection feature for access logs, Simple Log Service automatically generates a dedicated Metricstore named Logstore for access logs-metrics.

  Note

  The Metricstore stores the metrics that are generated after raw metrics are aggregated. The data volume significantly reduces after aggregation, and you can store aggregated metrics for a long period of time.
