     3. Click Log Dump Location next to Create to set up the log storage location.

        • Project: iot-log-${uid}-${regionId}, where ${uid} is your Alibaba Cloud account ID and ${regionId} is the region code of your IoT Platform service.

        • LogStore: iot-second-monitor-logs.

        • MetricStore: iot-second-monitor-metricstore.

        The default retention period for data in LogStore and MetricStore is 7 days.

     Upon enabling second-level monitoring, two scheduled SQL queries will be created within the corresponding Project in SLS: iot-message-transmit-second-monitor-scheduled-sql and iot-message-second-monitor-scheduled-sql.
