Multicast packets can pass across different networks through routers, so - it is possible to use multicasts in an Internet scenario as long as your network provider - supports multicasting. - - - Hosts that want to receive particular multicast messages must register their interest by joining - the multicast group. Multicast messages are not sent to networks where no host has joined - the multicast group.

On - the other hand, if the log is debug enabled, you - will incur the cost of evaluating whether the logger is debug - enabled twice. Once in and once in - the . This is an insignificant overhead - since evaluating a logger takes about 1% of the time it - takes to actually log. This is the preferred style of logging. - - Alternatively if your logger is available statically then the is debug - enabled state can be stored in a static variable like this: - - - private static readonly bool isDebugEnabled = log.IsDebugEnabled; - - - Then when you come to log you can write: - - - if (isDebugEnabled) - { - log.Debug("This is entry number: " + i ); - } - - - This way the debug enabled state is only queried once - when the class is loaded. Using a private static readonly - variable is the most efficient because it is a run time constant - and can be heavily optimized by the JIT compiler. - - - Of course if you use a static readonly variable to - hold the enabled state of the logger then you cannot - change the enabled state at runtime to vary the logging - that is produced.

The results - depend on the conversion pattern. - - - The conversion pattern is closely related to the conversion - pattern of the printf function in C. A conversion pattern is - composed of literal text and format control expressions called - conversion specifiers. - - - You are free to insert any literal text within the conversion - pattern. - - - Each conversion specifier starts with a percent sign (%) and is - followed by optional format modifiers and a conversion - pattern name. The conversion pattern name specifies the type of - data, e.g. logger, level, date, thread name. The format - modifiers control such things as field width, padding, left and - right justification. The following is a simple example. - - - Let the conversion pattern be "%-5level [%thread]: %message%newline" and assume - that the log4net environment was set to use a PatternLayout. Then the - statements - - - ILog log = LogManager.GetLogger(typeof(TestApp)); - log.Debug("Message 1"); - log.Warn("Message 2"); - - would yield the output - - DEBUG [main]: Message 1 - WARN [main]: Message 2 - - - Note that there is no explicit separator between text and - conversion specifiers. The pattern parser knows when it has reached - the end of a conversion specifier when it reads a conversion - character. In the example above the conversion specifier - %-5level means the level of the logging event should be left - justified to a width of five characters. - - - The recognized conversion pattern names are: - - - - Conversion Pattern Name - Effect - - - a - Equivalent to appdomain - - - appdomain - - Used to output the friendly name of the AppDomain where the - logging event was generated. - - - - c - Equivalent to logger - - - C - Equivalent to type - - - class - Equivalent to type - - - d - Equivalent to date - - - date - - - Used to output the date of the logging event in the local time zone. - To output the date in universal time use the %utcdate pattern. - The date conversion - specifier may be followed by a date format specifier enclosed - between braces.

The - logger conversion specifier can be optionally followed by - precision specifier, that is a decimal constant in - brackets. - - - If a precision specifier is given, then only the corresponding - number of right most components of the logger name will be - printed. By default the logger name is printed in full. - - - For example, for the logger name "a.b.c" the pattern - %logger{2} will output "b.c". - - - - - m - Equivalent to message - - - M - Equivalent to method - - - message - - - Used to output the application supplied message associated with - the logging event. - - - - - mdc - - - The MDC (old name for the ThreadContext.Properties) is now part of the - combined event properties.

The key to - lookup must be specified within braces and directly following the - pattern specifier, e.g. %property{user} would include the value - from the property that is keyed by the string 'user'. Each property value - that is to be included in the log must be specified separately. - Properties are added to events by loggers or appenders. By default - the log4net:HostName property is set to the name of machine on - which the event was originally logged. - - - If no key is specified, e.g. %property then all the keys and their - values are printed in a comma separated list. - - - The properties of an event are combined from a number of different - contexts.

This conversion specifier - can be optionally followed by precision specifier, that - is a decimal constant in brackets. - - - If a precision specifier is given, then only the corresponding - number of right most components of the class name will be - printed. By default the class name is output in fully qualified form. - - - For example, for the class name "log4net.Layout.PatternLayout", the - pattern %type{1} will output "PatternLayout". - - - WARNING Generating the caller class information is - slow.

Its use should be avoided unless execution speed - is not an issue. - - - - - utcdate - - - Used to output the date of the logging event in universal time. - The date conversion - specifier may be followed by a date format specifier enclosed - between braces. For example, %utcdate{HH:mm:ss,fff} or - %utcdate{dd MMM yyyy HH:mm:ss,fff}. If no date format specifier is - given then ISO8601 format is - assumed (). - - - The date format specifier admits the same syntax as the - time pattern string of the . - - - For better results it is recommended to use the log4net date - formatters.

However, - with the aid of format modifiers it is possible to change the - minimum field width, the maximum field width and justification. - - - The optional format modifier is placed between the percent sign - and the conversion pattern name. - - - The first optional format modifier is the left justification - flag which is just the minus (-) character. Then comes the - optional minimum field width modifier. This is a decimal - constant that represents the minimum number of characters to - output. If the data item requires fewer characters, it is padded on - either the left or the right until the minimum width is - reached. The default is to pad on the left (right justify) but you - can specify right padding with the left justification flag. The - padding character is space. If the data item is larger than the - minimum field width, the field is expanded to accommodate the - data. The value is never truncated. - - - This behavior can be changed using the maximum field - width modifier which is designated by a period followed by a - decimal constant. If the data item is longer than the maximum - field, then the extra characters are removed from the - beginning of the data item and not from the end. For - example, it the maximum field width is eight and the data item is - ten characters long, then the first two characters of the data item - are dropped. This behavior deviates from the printf function in C - where truncation is done from the end. - - - Below are various format modifier examples for the logger - conversion specifier. - -

- - Note about caller location information.
- The following patterns %type %file %line %method %location %class %C %F %L %l %M - all generate caller location information. - Location information uses the System.Diagnostics.StackTrace class to generate - a call stack. The caller's information is then extracted from this stack. - - - - The System.Diagnostics.StackTrace class is not supported on the - .NET Compact Framework 1.0 therefore caller location information is not - available on that framework. - - - - - The System.Diagnostics.StackTrace class has this to say about Release builds: - - - "StackTrace information will be most informative with Debug build configurations. - By default, Debug builds include debug symbols, while Release builds do not. The - debug symbols contain most of the file, method name, line number, and column - information used in constructing StackFrame and StackTrace objects. StackTrace - might not report as many method calls as expected, due to code transformations - that occur during optimization." - - - This means that in a Release build the caller information may be incomplete or may - not exist at all!
