Function Overview

  • Log Tank Service

    • Log Tank Service (LTS) collects log data from hosts and cloud services. By processing massive amounts of logs efficiently, securely, and in real time, LTS provides useful insights for you to optimize the availability and performance of cloud services and applications. It also helps you efficiently perform real-time decision-making, device O&M, and service trend analysis.
      Real-time log ingestion: You can ingest logs from hosts and cloud services using ICAgent, APIs, or SDKs.
      Log transfer: Log transfer is to create log copies in destination cloud services. You can transfer logs to Object Storage Service (OBS) or Data Ingestion Service (DIS) for long-term storage.

      Service Overview

      Getting Started

  • Log groups

    • A log group is a group of log streams which share the same log retention settings. Up to 100 log groups can be created for a single account.

      Creating a Log Group

  • Log streams

    • A log stream is the basic unit for reading and writing logs. You can separate different types of logs (such as operation logs and access logs) into different log streams for easier management. Sorting logs into different log streams makes it easier to find specific logs when you need them. Up to 100 log streams can be created in a log group.

  • Host management

    • ICAgent is the log collection tool of LTS. You need to install ICAgent on the hosts from which you want to collect logs.

  • Host groups

    • Host groups allow you to configure host log ingestion efficiently. You can sort multiple hosts to a host group and associate the host group with log ingestion configurations. The ingestion configurations will be applied to all the hosts in the host group, saving you the trouble of configuring the hosts one by one.

      • When there is a new host, simply add it to a host group and the host will automatically inherit the log ingestion configurations associated with the host group.
      • You can also use host groups to modify the log collection paths for multiple hosts at a go.

  • Ingesting ECS Text Logs to LTS

    • ICAgent collects logs from hosts based on your specified collection rules, and packages and sends the collected log data to LTS on a log-stream basis. You can view logs on the LTS console in real time.

  • Log transfer

    • LTS retains the log data reported by hosts and cloud services. To store logs for a long time, you can transfer them to other cloud services.

      The transfer to OBS function is available in all regions. However, other transfer destinations (DIS or DMS) are available only to whitelisted users. To enable these destinations, submit a service ticket.
