    Simple Log Service:Usage notes

    Last Updated:Aug 18, 2023

    Alibaba Cloud IoT Platform provides the log dump feature. You can use this feature to dump logs from IoT Platform to Simple Log Service. You can query, ship, and transform logs in real time in the Simple Log Service console. You can also visualize the results of log analysis and configure alerts. This topic describes the resources, billing, and limits of loT Platform logs.

    Assets

    • Dedicated project and Logstore

      After you enable the log dump feature, Simple Log Service creates a project named iot-log-Alibaba Cloud account ID-Region ID and a dedicated Logstore named iot_logs by default.

      Important

      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 dump feature, a dashboard is generated by default.

      Note

      The dedicated dashboard may be updated at any time. We recommend that you do not modify the dedicated dashboard. You can manually create a dashboard to visualize the results of log analysis. For more information, see Create a dashboard.

      Dashboard

      Description

      IoT operation center

      Shows the statuses and errors of devices that are connected to loT Platform. You can view the number of times that you have logged on and off the devices, device IP addresses distributed by region, and error distribution for data parsing script. You can also view the error distribution for Thing Specification Language (TSL) validation, the number of forwarded subscription messages at the server side, the number of forwarded cloud service messages, and error distribution for API calls.

    Billing

    • You are not billed when you use the log dump feature to dump logs.

    • If the dedicated Logstore uses the pay-by-feature billing mode, you are charged for storage, read traffic, number of requests, data transformation, and data shipping after the logs are collected from IoT Platform to Simple Log Service. The fees are included in the bills of Simple Log Service. For more information, see Billable items of pay-by-feature.

    • If the dedicated Logstore uses the pay-by-ingested-data billing mode, you are charged only for read traffic over the Internet after the logs are collected from IoT Platform to Simple Log Service. The fees are included in the bills of Simple Log Service. For more information, see Billable items of pay-by-ingested-data.

    Limits

    • You can write only IoT Platform logs to a dedicated Logstore. You cannot modify the indexes of the Logstore.

    • You cannot delete dedicated projects or Logstores.

    • You can create only one log configuration file in each region. The operational logs of all cloud services in the region are automatically dumped to the dedicated Logstore based on the log collection configurations in the file.
