Logging client connections and other system events 35

Access log file

Flash Media Server 2 maintains an access log that includes statistics about client connections

and stream activity. Flash Media Server 2 also maintains application logs for application

activities and application logs for diagnostic logs. The application and diagnostic logs are an

addition to operating system logs that log error and informational messages about Flash

Media Server 2 operations.

The access log records information about requests by Flash Player and Flash Media Server 2

application instances. Using these logs, you can find out when a user connected to the server,

the total bandwidth consumed during the session, and information about resources such as

the streams accessed by the connection. You can use this information to determine which

applications are the most frequently used.

The default access log is access.xx.log, which is located in the Flash Media Server 2 logs

directory. The default configuration for Flash Media Server 2 creates a single access log per

server. You can also configure Flash Media Server 2 to create a separate file per vhost. When

logging is configured on a per-vhost basis, all logs for a particular vhost are found in a

subdirectory within the logs directory. The name of the subdirectory matches the vhost name.

Substitution strings can be found in the [] brackets, YYYY, MM, DD, and NN representing

year, month, date, and version. You can use the substitution string to customize the filename

of the access log.

To configure the server to create separate log files for each vhost, set the value of the

Scope tag

in the Server.xml file to “vhost” (see the description of the tag “Scope” on page 117).

For more information on logging, see “Logger.xml file” on page 135.

Flash Media Server 2 defines event categories, and for each category it defines events that can

be recorded. Logging can be customized to record all events or only specific events. This

determines how much information is collected.

The following table lists the access events defined in the Access logs.
