The following describes each field of Global Edge standard log stored in the user bucket.

Log field name Description
date This is the date of event and the date is displayed in the MM/D/YY format (based on UTC).
time This is the time when a response is completed in response to a request by the Global Edge server and the time is displayed in the HH:MM:SS format (based on UTC).
c-ip IP address of the last user
c-port Port number used to connect to the Global Edge server in response to the last user's request
X-Forward-For Standard header for identifying the IP address of the last user when the last user's request through the HTTP proxy or load balancer
cs-method HTTP request method received from the last user
cs-uri-host HTTP Host header information in response to the last user's request
cs-uri-stem Request URI or a portion thereof for identifying the path and object in response to the last user's request
cs-uri-query Query strings of URL requested by the last user
cs-range HTTP Range header information in response to the last user's request
cs-acceptencoding This is the HTTP Accep-Encoding header for compression transfer with the last user and algorithm information used for compression transfer requested by the last user
s-pop Global Edge location information that processed the request
server-ip Global Edge server IP information that processed the request
time-response This is the time (millisecond) taken for responding to the first byte after the Global Edge server receives the request and the measured value in the server.
time-taken This is the time (millisecond) taken for responding to the last byte after the Global Edge server receives the request and the measure value in the server. Due to the network latency in the lastmile section, TCP buffering, and the like, the response time is greater than the time-taken value in the last user's perspective.
sc-cachehit Classification information of the operation type of the Global Edge server responded to the last user
  • MISS: because the cached object cannot be found, request an object to the origin and transmit it to the last user by receiving a response
  • HIT: transmit cached objects to the last user
  • BYPASS: always request an object to the origin server rather than caching the object in the Global Edge server and transmit it to the last user by receiving a response
  • EXPIRED: as the cached object TTL has expired, transmit the request to the origin and update the cached object and transmit it to the last user
  • STALE: if it is failed to check the object validity due to an issue in the origin server status, transmit the object of which the cache TTL has expired to the last user (in case where Serve stale if unable validate setting is applied to Serve Stale object setting in the cache setting field)
  • REVALIDATE: as the TTL of the cached object has expired, check (revalidate) that it is still a valid object when verifying the validity from the origin server and transmit it to the last user
    		•
    sc-status HTTP status code of the Global Edge server response in response to the request
    sc-bytes The number of total bytes transmitted to the last user by the Global Edge server (including the header)

    cs-procol-version Protocol version information of the last user's request
