public GPUdbLogger()

Method Detail

initializeLogger

public static void initializeLogger()

Initializes the default logger with the value of the 'logging.level.com.gpudb' system property. Log level can be set when executing a jar with a '-Dlogging.level.com.gpudb=DEBUG' arg.

info

public static void info(String message)

error

public static void error(String message)

error

public static void error(Throwable exception,
                         String message)

warn

public static void warn(String message)

debug

public static void debug(String message)

trace

public static void trace(String message)

isDebugEnabled

public static boolean isDebugEnabled()

isTraceEnabled

public static boolean isTraceEnabled()

debug_with_info

public static void debug_with_info(String message)

Print extra information with the debug message.

trace_with_info

public static void trace_with_info(String message)

Print extra information with the trace message.

setLoggingLevel

public static boolean setLoggingLevel(String logLevel)

Dynamically set the log level for the 'com.gpudb' logger at runtime. Supports multiple SLF4J backend implementations:

• Logback - Native SLF4J implementation (most common)
• Log4j2 - Apache Log4j 2.x via slf4j-log4j2 binding
• JUL - Java Util Logging via slf4j-jdk14 binding

Note: slf4j-simple does not support runtime log level changes. For slf4j-simple, set the level via system property at startup: -Dorg.slf4j.simpleLogger.defaultLogLevel=DEBUG

Parameters:

logLevel - One of the supported log levels: TRACE, DEBUG, INFO, WARN, ERROR, OFF. null value is treated as 'OFF'.

Returns:

true if the log level was successfully set, false if no supported backend was detected or an error occurred.

setDependencyLogLevel

public static boolean setDependencyLogLevel(String loggerName,
                                            String logLevel)

Sets the log level for a dependent library logger. Useful for silencing verbose third-party libraries.

Parameters:

loggerName - The fully qualified logger name (e.g., "org.apache.http")

logLevel - The desired log level

Returns:

true if successful, false otherwise
