| Each <a href="T_log4net_Core_LoggingEvent.htm" target="">LoggingEvent</a> has an associated <span class="selflink">Level</span>. |
| </p><p> |
| Levels have a numeric <a href="P_log4net_Core_Level_Value.htm" target="">Value</a> that defines the relative |
| ordering between levels. Two Levels with the same <a href="P_log4net_Core_Level_Value.htm" target="">Value</a> |
| are deemed to be equivalent. |
| </p><p> |
| The levels that are recognized by log4net are set for each <a href="T_log4net_Repository_ILoggerRepository.htm" target="">ILoggerRepository</a> |
| and each repository can have different levels defined. The levels are stored |
| in the <a href="P_log4net_Repository_ILoggerRepository_LevelMap.htm" target="">LevelMap</a> on the repository. Levels are |
| looked up by name from the <a href="P_log4net_Repository_ILoggerRepository_LevelMap.htm" target="">LevelMap</a>. |
| </p><p> |
| When logging at level INFO the actual level used is not <a href="F_log4net_Core_Level_Info.htm" target="">Info</a> but |
| the value of <span class="code">LoggerRepository.LevelMap["INFO"]</span>. The default value for this is |
| <a href="F_log4net_Core_Level_Info.htm" target="">Info</a>, but this can be changed by reconfiguring the level map. |
| </p><p> |
| Each level has a <a href="P_log4net_Core_Level_DisplayName.htm" target="">DisplayName</a> in addition to its <a href="P_log4net_Core_Level_Name.htm" target="">Name</a>. The |
| <a href="P_log4net_Core_Level_DisplayName.htm" target="">DisplayName</a> is the string that is written into the output log. By default |
| the display name is the same as the level name, but this can be used to alias levels |
| or to localize the log output. |
| </p><p> |
| Some of the predefined levels recognized by the system are: |
| </p><ul><li><a href="F_log4net_Core_Level_Off.htm" target="">Off</a>.</li><li><a href="F_log4net_Core_Level_Fatal.htm" target="">Fatal</a>.</li><li><a href="F_log4net_Core_Level_Error.htm" target="">Error</a>.</li><li><a href="F_log4net_Core_Level_Warn.htm" target="">Warn</a>.</li><li><a href="F_log4net_Core_Level_Info.htm" target="">Info</a>.</li><li><a href="F_log4net_Core_Level_Debug.htm" target="">Debug</a>.</li><li><a href="F_log4net_Core_Level_All.htm" target="">All</a>.</li></ul><a name="seeAlsoSection"><!----></a><div class="OH_CollapsibleAreaRegion"><div class="OH_regiontitle">See Also</div><div class="OH_CollapsibleArea_HrDiv"><hr class="OH_CollapsibleArea_Hr" /></div></div><div class="OH_clear"></div><div class="seeAlsoStyle"><a href="AllMembers_T_log4net_Core_Level.htm" target="">Level Members</a></div><div class="seeAlsoStyle"><a href="N_log4net_Core.htm" target="">log4net.Core Namespace</a></div></div></div></div></div><div id="OH_footer" class="OH_footer"><p>Apache log4net, Apache and log4net are trademarks of The Apache Software Foundation.</p><p><a href="http://logging.apache.org/log4net/" target="_blank"><img src="./../icons/online_icon.gif" class="OH_offlineIcon" alt="Online" title="Online" /> |
