# Collecting Accounting Statistics

You can use the aaa accounting statistics command to specify how the AAA server collects statistics on the sessions it manages. Use the volume-time keyword to specify that AAA notifies applications to collect a full set of statistics from each of their connections. Use the time keyword to specify that only the uptime status is collected for each connection. Collecting only uptime information reduces the amount of data sent to AAA and is a more efficient use of system resources for customers that do not need a full set of statistics. The router collects a full set of statistics by default.
