Logging is the part of\u00a0development\u00a0which is normally not included in Product \/ Software release but\u00a0at the same time it is necessary to create the logging mechanism in your software\u00a0module.<\/strong><\/p>\n

\"implement<\/a><\/p>\n

<\/p>\n

Without logging, how you will track<\/p>\n

    \n
  1. run time errors and exceptions in Websites<\/li>\n
  2. Status of Windows service.<\/li>\n
  3. Softwares which will run in background.<\/li>\n
  4. Crash reports etc.<\/li>\n<\/ol>\n

    In this article i am going to explain that how to configure the log 4 net <\/strong>in you .net based applications.<\/p>\n

    To start with, you have to download the log 4 net from here<\/a>.<\/p>\n

    After downloading, you will need to set the configurations related to Log4net. (web.config <\/strong>in case of websites else app.config<\/strong>)<\/p>\n

    code snapshot in configuration file:<\/p>\n

    \n<configSections>\n    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" \/>\n  <\/configSections>\n <log4net>\n    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender,log4net">\n      <file value="Logs\/Notification" \/>\n      <appendToFile value="true" \/>\n      <rollingStyle value="Date" \/>\n      <StaticLogFileName value="false"\/>\n      <datePattern value="-dd-MMM-yy'.log'" \/>\n      <!--Roll every Day-->\n      <maxSizeRollBackups value="-1" \/>\n      <!--Infinite backups-->\n      <maximumFileSize value="2MB" \/>\n      <!--Maximum size of 1 file-->\n      <layout type="log4net.Layout.PatternLayout">\n        <!-- http:\/\/logging.apache.org\/log4net \/release\/sdk\/log4net.Layout.PatternLayout.html -->\n        <conversionPattern value="%date{dd-MMM-yy, HH:mm:ss} - %5level [%thread] - %message%newline " \/>\n      <\/layout>\n    <\/appender>\n    <appender name="SmtpAppender" type="log4net.Appender.SmtpAppender">\n      <to value="EMAIL" \/>\n      <from value="EMAIL" \/>\n      <subject value="Error in Component" \/>\n      <smtpHost value="SMTP SERVER" \/>\n      <bufferSize value="512" \/>\n      <lossy value="true" \/>\n      <evaluator type="log4net.Core.LevelEvaluator">\n        <threshold value="FATAL"\/>\n      <\/evaluator>\n      <layout type="log4net.Layout.PatternLayout">\n        <conversionPattern value="%newline%5level [%thread] [%file]- %message%newline " \/>\n      <\/layout>\n    <\/appender>\n    <root>\n      <!-- Ascending Priority: Debug,Info,Warn,Error,Fatal,ALL -->\n      <priority value="ALL" \/>\n      <appender-ref ref="RollingLogFileAppender" \/>\n      <appender-ref ref="SmtpAppender" \/>\n    <\/root>\n  <\/log4net>\n<\/pre>\n
    You can find the description inline in configuration.<\/p>\n
    For more info, you can visit this site.<\/a><\/p>\n
    To use log 4 net in code, after configuration you have to initialize the object of log 4 net like below line of code.<\/p>\n
    \n private static readonly ILog logger = LogManager.GetLogger(typeof(Program));\n<\/pre>\n
    After initialization, We have to configure the log 4 net.<\/p>\n
    \nXmlConfigurator.Configure();\n<\/pre>\n
    To log we can decide the log levels:
    \nThere are five log levels:<\/p>\n
      \n
    • Fatal (Highest Level)<\/strong><\/li>\n
    • Warn<\/strong><\/li>\n
    • Error<\/strong><\/li>\n
    • Debug<\/strong><\/li>\n
    • Info (Lowest Level)<\/strong><\/li>\n<\/ul>\n
      \n            XmlConfigurator.Configure();\n            logger.Info(new Exception("This is test Exception"));\n            logger.Debug(new Exception("This is test Exception"));\n            logger.Error(new Exception("This is test Exception"));\n            logger.Warn(new Exception("This is test Exception"));\n            logger.Fatal(new Exception("This is test Exception"));\n<\/pre>\n","protected":false},"excerpt":{"rendered":"
