Status Code Statistics

Last updated: 2020-04-28 14:50:53

    ECDN status code statistics allow you to query monitoring data of status codes. You can log in to the ECDN Console and click Statistics on the left sidebar to enter the Status Code Statistics page and try out this feature.

    Query Condition Description

    • Time Period: you can query data in the last 12 calendar months with a maximum time span of 31 days.
    • Project: you can query usage by project.
    • Domain Name: you can query usage of the specified domain name.
    • Granularity: it indicates the granularity of queried data and is subject to the selected time period.
      1. If the selected time period is 1 day, you can query data at a granularity of 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, or 4 hours.
      2. If the selected time period is 2–3 days, you can query data at a granularity of 15 minutes, 30 minutes, 1 hour, 2 hours, or 4 hours.
      3. If the selected time period is 4–7 days, you can query data at a granularity of 30 minutes, 1 hour, 2 hours, or 4 hours.
      4. If the selected time period is 8–30 days, you can query data at a granularity of 1 hour, 2 hours, or 4 hours.

    Notes on Status Code Data Display

    Status code data can be displayed in two modes: status data distribution pie chart and status code trend curve. All data can be exported.

    • All domain names that were connected in the last 30 days, including deleted ones, will be included in the All Domain Names drop-down list.
    • The real-time monitoring data on the current day is delayed for about 5 minutes. If you perform a query at 14:26:00, the query result will generally include data between 00:00:00 and 14:21:00 on the day.
    • Monitoring statistics are grouped by granularity. For example, if the query granularity is 5-minute, statistics between 10:00:00 and 10:04:59 will be grouped to the 10:00:00 sample point.
    • If the specified query time period is longer than the domain name connection period, only the statistics of the connection period will be displayed, while the time period during which the domain name has not been connected or has been deleted will be excluded.
    • To query monitoring data of multiple domain names or metrics, you can use the GetDsaStatistics API.

    Status Code Description

    Category Status Code Description Solution
    2XX 200 The access succeeds. A 2XX status code generally indicates a normal access state.
    206 The access succeeds.
    3XX 301 The accessed content has been permanently migrated. A 3XX status code generally indicates a normal access state.
    302 The access is redirected.
    304 The content to be accessed has not changed.
    4XX 400 A request parameter is incorrect. A 4XX status code generally indicates that the client request is incorrect or the acceleration service of the domain name has been disabled.
    401 The access request verification fails.
    403 Access to the content is denied.
    404 The requested content cannot be found.
    405 The request method is not supported.
    416 The range is invalid.
    5XX 500 An internal server error occurs. Please check whether the origin server service is exceptional; and if not, please submit a ticket for assistance.
    502 The server cannot provide service currently.
    501 The request method is not supported by the server and cannot be processed. Please check the request method.
    513 The ECDN edge server is overloaded, which is generally caused by user request surge or CC attacks. Please check whether the business request surge of the domain name is normal.
    522 Internal HTTP ECDN connection establishment fails, or HTTP ECDN origin-pull connection establishment fails. Please check whether the origin server port 80 has been opened.
    529 The domain name is newly added, and the route configuration has not taken effect. It takes 5–10 minutes for the platform to deploy the configuration. Please confirm that the configuration has taken effect before switching the CNAME resolution.
    The ping command is blocked by the origin server, and the origin-pull route information cannot be obtained. You need to grant the ping permission on your ECDN intermediate nodes. You can submit a ticket to get the list of IPs of ECDN intermediate nodes.
    533 ECDN edge or relay transfer fails, read times out, or connection establishment fails. Please submit a ticket for assistance.
    538 HTTPS SSL handshake fails, internal ECDN transfer fails, or ECDN origin-pull SSL handshake fails. Please check whether the origin server port 443 has been opened and SSL handshake is normal.
    564 ECDN origin-pull times out. Please check whether there are jitters on the origin server egress network.
    Other 0 The client actively closes the connection during response. Generally, it is caused by a client network problem or active stop of access by the user. If you find that user access is affected, please submit a ticket for assistance.
