Appender in eiam.log4net.config

An appender contains parameters that control the logging of each logger. By default, the logger configuration files contains the following appenders:

• SDK

  Logs the SDK messages into a log file. Specifies the path including the file name of the log file.

  Default: EIAM.C#SDK.log

  Note: If you are deploying your application under Tomcat server on Windows, ensure that you use forward slash '/' in the path instead of the backward slash '\'. If you use backward slash, the log file is not created at the path you have specified; instead, the log file is created in the Apache Tomcat folder.

• Network

  Logs the network call related messages into a log file.

  Default:EIAM.NETWORK.C#SDK.log

• Performance

  Logs the performance call related messages into a log file.

  Default: EIAM.PERFORMANCE.C#SDK.log

• Console

  Displays the log messages on the console.

SDK appender is enabled by default. To enable other appenders, remove the comment strings (<!-- and -->) from their respective code.

An appender consists of the following configurable parameters:

• file

  Specifies the log filename of the appender.

• appendToFile

  Specifies if a set of log messages is appended to the log file. If the value is true, the set of log message is appended to the last log message in the log file.

• maxSizeRollBackups

  Specifies the maximum number of backup log files used for keeping old logs. If the number of log files exceeds the maximum backup index value, the file with the oldest log messages is deleted.

  Default: 1

  Minimum: 1

  Maximum: 12

• rollingStyle

  Specifies if the latest log message is buffered. If the value is true, latest few log messages are kept in memory before writing to log file. This minimizes IO operation and is beneficial if the log level is higher.

  Value: [true|false]

  Default: false

  Note: The default size of BufferedIO is 8 KB.

• maximumFileSize

  Specifies the maximum size of the log file. If a log file exceeds the maximum size, a new log file filename log.1 is created and the contents of log file are transferred to log.1 file. The log file now contains latest log messages. If this file too exceeds the maximum size, a new log file filename log.2 is created, the contents of log.1 are transferred to log.2 file, and the contents of log file are transferred to log.1 file.

  Default: 10 MB

  Minimum: 10 KB

  Maximum: 2 GB

  Note: The minimum size of the maxFileSize must be greater than or equal to the size of rollingStyle.

• ConversionPattern

  Specifies the formatting of a log message. Configure the format modifiers and conversion characters to define the conversion pattern.

  Note: For more information about conversion patterns, refer the topic log4net in www.apache.org.
