Accounting Files
When a policy has been created and applied to a service, the accounting file is stored on the
compact flash in a compressed XML file format. The 7705 SAR creates two directories on
the compact flash to store the files. The following output displays a directory named
act-
collect
that holds accounting files that are open and actively collecting statistics, and a
directory named
act that stores the files that have been closed and are awaiting retrieval.

12/19/2006 06:08a <DIR> act-collect
12/19/2006 06:08a <DIR> act
ALU-1>file cf3:\act-collect\ # dir
Directory of cf3:\act-collect#

Accounting files always have the prefix act followed by the accounting policy ID, log ID
and timestamp. The accounting log file naming and log file destination properties (such as
rollover and retention) are discussed in more detail in Log Files on page 199.
A file ID can only be assigned to either one event log ID or one accounting log.
Design Considerations
The 7705 SAR has ample resources to support large-scale accounting policy deployments.
When preparing for an accounting policy deployment, verify that data collection, file
rollover, and file retention intervals are properly tuned for the amount of statistics to be
collected.
If the accounting policy collection interval is too brief, there may be insufficient time to
store the data from all the services within the specified interval. If that is the case, some
records may be lost or incomplete. Interval time, record types, and number of services using
an accounting policy are all factors that should be considered when implementing
accounting policies.
The rollover and retention intervals on the log files and the frequency of file retrieval must
also be considered when designing accounting policy deployments. The amount of data
stored depends on the type of record collected, the number of services that are collecting
statistics, and the collection interval that is used.
