Each cache device aggregates its statistics before sending them to Content Accountant Server. Then Content Accountant Server also aggregates the statistics from all the devices before sending them to the FTP server.
Statistics are sent to the FTP server in one of three formats:
This format stores a log entry for each request.
This format stores a log entry for each request.
This format reports aggregated statistics
SQUID and Extended W3C are useful for content networks that need to track and report on single objects in small collections. For example, if you are tracking large media files and need to know exact information regarding each object usage, SQUID or W3C would provide that information. If large numbers of object requests are logged, the data collected becomes very large very quickly and can consume large amounts of network bandwidth for transmission. For example, 5,000 requests for a single object result in 5,000 entries in the logged data.
Summarized W3C is useful for content networks that have large sites with many objects. Because content usage data is summarized, bandwidth required for data transfers is less by orders of magnitude. For example, 5,000 requests for a single object result in one log entry.
