logG Source #

Arguments

:: LogLevel	Log severity level
-> ByteString	Log message
-> IO ()

Logs a message to the global Nginx log.

logM Source #

Arguments

:: LogLevel	Log severity level
-> Ptr ()	Pointer to the Nginx request object
-> ByteString	Log message
-> IO ()

Logs a message to the request's Nginx log.

This function accepts a pointer to the Nginx request object supposedly unmarshalled from Nginx variable $_r_ptr.

logR Source #

Arguments

:: LogLevel	Log severity level
-> ByteString	Log message
-> IO ()

Logs a message to the request's Nginx log.

This function expects that the log message contains the value of Nginx variable $_r_ptr at the beginning of the log message. All whitespace characters following the value of $_r_ptr are skipped.

logStderr Source #

Arguments

:: ByteString	Log message
-> IO ByteString

Logs a message with severity LogStderr to the global Nginx log.

This is the core function of the logStderr handler.

:: ByteString	Log message
-> IO ByteString

Logs a message with severity LogEmerg to the global Nginx log.

This is the core function of the logEmerg handler.

logAlert Source #

Arguments

:: ByteString	Log message
-> IO ByteString

Logs a message with severity LogAlert to the global Nginx log.

:: ByteString	Log message
-> IO ByteString

Logs a message with severity LogCrit to the global Nginx log.

This is the core function of the logCrit handler.

logErr Source #

Arguments

:: ByteString	Log message
-> IO ByteString

Logs a message with severity LogErr to the global Nginx log.

This is the core function of the logErr handler.

This is the core function of the logNotice handler.

logInfo Source #

Arguments

:: ByteString	Log message
-> IO ByteString

This is the core function of the logDebug handler.

logStderrR Source #

Arguments

:: ByteString	Log message
-> IO ByteString

Logs a message with severity LogStderr to the request's Nginx log.

This is the core function of the logStderrR handler.

logEmergR Source #

Arguments
