Log4net log output format-log4net. layout. patternlayout usage

Characters	Effect
A	EquivalentAppdomain
Appdomain	Used to output the friendly name of the appdomain where the logging event was generated. A friendly name used to indicate the appdomain generated by a daily event.
C	EquivalentLogger
C	EquivalentType
Class	EquivalentType
D	EquivalentDate
Date	The date used to indicate the date of the sunrise event in the previous time zone. to export a common time, use the % utcdate mode. after a date Delimiter is specified, a pair of tokens can be matched with the delimiter. The Delimiter is specified for the date format. for example:% Date {hh: mm: SS, fff}Or% Date {dd Mmm yyyy hh: mm: SS, fff },If no format is specified, it is deemed as iso8601 (iso8601dateformatter ). The format of the Delimiter is the same as that of the tostring. We recommend that you use the log4net date formatter to improve the effect of loading to logs. They can use the following strings: "absolute", "date", "ISO 8601" To specify absolutetimedateformatter, datetimedateformatter, andIso8601dateformatter.For example: % Date {iso8601}Or% Date {absolute}. The date formatter used for these operations is much better than the tostring.
Exception	Used when the same day when the same token information is merged. If a regular photo object is stored in a daily registration event, it will be output in the trailing newline mode. No, no.
F	EquivalentFile
File	Used to export the name of the file requested by log reference. Example: C: \ Inetpub \ wwwroot \ logtest \ webform1.aspx. CS Warning:The location information of the production caller is relatively slow. The number of callers should not be used unless the record speed is not a problem.
Identity	Used to specify the principal name (principal. Identity. Name) used before execution ). Warning:The location information of the production caller is relatively slow. The number of callers should not be used unless the record speed is not a problem.
L	EquivalentLocation
L	EquivalentLine
Location	The location information of the caller who generates the birthday event. This location information is based on the actual situation of CLI, but it is usually named as a method with a limited space and is used to include the caller's name and line numbers. Example: logtest. webform1.button3 _ click (C: \ Inetpub \ wwwroot \ logtest \ webform1.aspx. CS: 93) Location information is very useful. However, its production is quite slow. The number of snapshots should not be used unless the speed of the rows is not a problem.
Level	It is used to record events.
Line	Used to parse the line for sending the log reporter request. Warning:The location information of the production caller is relatively slow. The number of callers should not be used unless the record speed is not a problem.
Logger	This parameter is used to indicate the name of the day when a daily event is generated. this day's response character can follow the precision. The precision is a constant of 10 hexadecimal notation, which is enclosed by flowers. if an accuracy character is specified, only the corresponding data names from right to left are displayed, and all values are entered. The name of A. B. C is as follows ",% Logger {2}"B. C"
M	EquivalentMessage
M	EquivalentMethod
Message	Used to compile the information provided by the application to log on to the event.
MDC	MDC (Region name: threadcontext. properties) is a part of the event consistency. This mode supports compatibility, but is equivalentProperty.
Method	The name of the method used to calculate the log reference. Warning:The location information of the production caller is relatively slow. The number of callers should not be used unless the record speed is not a problem.
N	EquivalentNewline
Newline	Limit row, equivalent to "\ n" or "\ r \ n"
P	EquivalentLevel
P	EquivalentProperty
Properties	EquivalentProperty
Property	It is used to specify the adequacy of an event. the property name should be included in the parameter and placed directly behind the property. example: % property {user }. every attention in the Daily Routine must be specified by the daily routine. properties is added to the event by the log recorder or append. the default value is log4net: Hostname, which is the name of the machine that generates the event. If no irrelevant word is specified, for example:% Property, The shard value will be used to tease the shard list
R	EquivalentTimestamp
T	EquivalentThread
Timestamp	Used to indicate the time when a program was created from a program event to a daily event, in milliseconds.
Thread	It is used to indicate the name of the program that initiates a daily event. If no program name is specified, the program name is used.
Type	Use the same Logger Warning:The location information of the production caller is relatively slow. The number of callers should not be used unless the record speed is not a problem.
U	EquivalentIdentity
Username	Used to extract the windowsidentity that was previously used Warning:The location information of the production caller is relatively slow. The number of callers should not be used unless the record speed is not a problem.
Utcdate	Use the same date
W	EquivalentUsername
X	EquivalentNDC
X	EquivalentMDC
%	% Outgoing one %
