General :

Private Key – A unique ID which represents your company, this Id will be sent to your mail once you register to Coralogix.

Application Name – The name of your main application, for example, a company called “SuperData” would probably insert the “SuperData” string parameter or if they want to debug their test environment they might enter the “SuperData– Test”.

SubSystem Name – Your application probably has multiple subsystems, for example, Backend servers, Middleware, Frontend servers, etc. to help you examine the data you need, inserting the subsystem parameter is vital.

Via Log4NET configuration XML:

<?xml version="1.0" encoding="utf-8" ?>
  <appender name="CoralogixLog4NetAppender" type="CoralogixLog4Net.CoralogixLog4NetAppender, CoralogixLog4Net" >
    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date [%thread] %-5level %logger [%ndc] - %message%newline" />
    <level value="INFO" />

Via code:

//Initilizing new CoralogixLog4Net appender.

CoralogixLog4NetAppender coralogixAppender = new CoralogixLog4NetAppender();

coralogixAppender.PrivateKey = "11111111-1111-1111-1111-111111111111";

coralogixAppender.ApplicationName = "MyTestApp";

coralogixAppender.SubsystemName = "BL";

//Configure the Level filter for the Coralogix Appender

var coralogixFilter = new log4net.Filter.LevelRangeFilter();

coralogixFilter.LevelMin = Level.All;



//Adding the Coralogix log4Net appender to the Repository

var root = ((log4net.Repository.Hierarchy.Hierarchy)LogManager.GetRepository()).Root;

var attachable = root as IAppenderAttachable;

if (attachable != null)




// Define the actual log4net logger which through it all log entires should be reported

ILog logger = log4net.LogManager.GetLogger(typeof(Program));

//Activate the Coralogix appender to the log4net logger which was just created above
