TrinityCore的日志有六个级别：Trace，Debug，Info，Warn，Error，Fatal
它们分别对应以下这六个接口，（filterType__也是在配置文件中指定的）
#define TC_LOG_TRACE(filterType__, ...) #define TC_LOG_DEBUG(filterType__, ...) #define TC_LOG_INFO(filterType__, ...) #define TC_LOG_WARN(filterType__, ...) #define TC_LOG_ERROR(filterType__, ...) #define TC_LOG_FATAL(filterType__, ...)
说明：这个在配置文件的注释中说得很详细，直接帖两段吧
Appender配置：
# Appender config values: Given a appender "name" # Appender.name # Description: Defines 'where to log' # Format: Type,LogLevel,Flags,optional1,optional2,optional3 # # Type # 0 - (None) # 1 - (Console) # 2 - (File) # 3 - (DB) # # LogLevel # 0 - (Disabled) # 1 - (Trace) # 2 - (Debug) # 3 - (Info) # 4 - (Warn) # 5 - (Error) # 6 - (Fatal) # # Flags: # 0 - None # 1 - Prefix Timestamp to the text # 2 - Prefix Log Level to the text # 4 - Prefix Log Filter type to the text # 8 - Append timestamp to the log file name. Format: YYYY-MM-DD_HH-MM-SS (Only used with Type = 2) # 16 - Make a backup of existing file before overwrite (Only used with Mode = w) # # Colors (read as optional1 if Type = Console) # Format: "fatal error warn info debug trace" # 0 - BLACK # 1 - RED # 2 - GREEN # 3 - BROWN # 4 - BLUE # 5 - MAGENTA # 6 - CYAN # 7 - GREY # 8 - YELLOW # 9 - LRED # 10 - LGREEN # 11 - LBLUE # 12 - LMAGENTA # 13 - LCYAN # 14 - WHITE # # File: Name of the file (read as optional1 if Type = File) # Allows to use one "%s" to create dynamic files # # Mode: Mode to open the file (read as optional2 if Type = File) # a - (Append) # w - (Overwrite) # # MaxFileSize: Maximum file size of the log file before creating a new log file
# Appender config values: Given a appender "name" # Appender.name # Description: Defines 'where to log' # Format: Type,LogLevel,Flags,optional1,optional2,optional3 # # Type # 0 - (None) # 1 - (Console) # 2 - (File) # 3 - (DB) # # LogLevel # 0 - (Disabled) # 1 - (Trace) # 2 - (Debug) # 3 - (Info) # 4 - (Warn) # 5 - (Error) # 6 - (Fatal) # # Flags: # 0 - None # 1 - Prefix Timestamp to the text # 2 - Prefix Log Level to the text # 4 - Prefix Log Filter type to the text # 8 - Append timestamp to the log file name.

Appender.Console=1,3,0 Appender.Server=2,2,0,Server.log,w Logger.root=2,Console Server
以上这三句，定义了两个Appender:Console, Server，一个log type:root
Appender.Console说明将日志输出到终端上，最低输出级别是Info，输出字体颜色是黑色（因终端的不同而不同）
Appender.Server说明将日志输出到文件，最低输出级别是Debug，输出文件是（Server.log），以重写（非添加）的方式写入
Logger.root最低输出级别是Info，使用Console和Server的配置
这里简单地说一下，就不太深入了
以 TC_LOG_INFO("qch","Hello, world"); 为例子
这句实现上是调用了
if(Log::instance()::ShouldLog("qch", LOG_LEVEL_INFO) )
Log::instance()::outMessage ("qch", LOG_LEVEL_INFO, "Hello,world");outMessage就比较麻烦了，层层调用，有兴趣的可以去看看，这里就不多作解释了。
如果把Appender的Type设为3（DB），那每写一条日志，就是在auth库的logs表中插入一条记录：
INSERTINTO logs (time, realm, type, level, string) VALUES (1409544332, 0, 'qch', 3,'Hello, world\n')
