    • Resource monitoring
      You can view and download the details about the following metrics by domain name, region, provider, time granularity (1 minute, 5 minutes, or 1 hour), and time range (today, yesterday, last seven days, last 30 days, or a custom period).
      Item Metric
      Traffic/Bandwidth Bandwidth and traffic
      Back-to-origin Statistics Back-to-origin bandwidth and back-to-origin traffic
      Visits Requests and QPS
      Hit Rate None
      HTTPCODE 5xx, 4xx, 3xx, and 2xx status codes

      Resource monitoring

      The data shown in the resource monitoring line chart differs slightly from the billing data. For example, a 30-day resource statistics line chart is plotted at 14,400s intervals, while the billing data is plotted at 300s intervals. The line chart does not take into account certain points and is mainly used to show the bandwidth trend. The billing data has finer granularity to help you calculate the actual bandwidth usage.

    • Real-time monitoring
      You can view the details about the following metrics by domain name, region, provider, and time range (last hour, last 6 hours, last 12 hours, or a custom period).
      Item Metric
      Basic Data Bandwidth, traffic, requests, and QPS
      Back-to-origin Statistics Back-to-origin bandwidth and back-to-origin traffic
      Quality Monitoring Request hit rate, byte hit rate, 5xx, 4xx, 3xx, and 2xx status codes
