Accounting Files
When a policy has been created and applied to a service or network port, the accounting file is
stored on the compact flash in a compressed XML file format. The router 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. The directory named act
stores the files that have been closed and are awaiting retrieval.

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 like rollover and
retention are discussed in more detail in
Design Considerations
The router 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. For example, with a 1GB CF and using the default collection interval, the
system is expected to hold 48 hours worth of billing information.
