Logger

Page Summary

Logger is a simple interface for logging error, warning, info, debug, and verbose messages within Google Tag Manager.
By default, Google Tag Manager logs errors and warnings, while ignoring info, debug, and verbose messages.
Developers can customize logging behavior by implementing the Logger interface and setting it using TagManager.setLogger(Logger).
The logging level can be adjusted using TagManager.getLogger().setLogLevel(level) to control the types of messages that are output.
The Logger interface provides methods for logging messages at different levels: d (debug), e (error), i (info), v (verbose), and w (warning), with optional Throwable parameters for exceptions.

Known Indirect Subclasses

TagManager.Logger

A simple interface for error/warning/info/debug/verbose logging.

By default, Google Tag Manager logs error/warning messages and ignores info/debug/verbose messages. You can install your own logger by calling setLogger(Logger) or set your own log level by calling TagManager.getLogger().setLogLevel(level);.

Public Methods

public abstract void d (String message)

Logs a debug message.

public abstract void d (String message, Throwable t)

Logs a debug message.

public abstract void e (String message, Throwable t)

Logs an error message.

public abstract void e (String message)

Logs an error message.

public abstract Logger.LogLevel getLogLevel ()

Returns the current log level.

public abstract void i (String message, Throwable t)

Logs an info message.

public abstract void i (String message)

Logs an info message.

public abstract void setLogLevel (Logger.LogLevel logLevel)

Sets the log level. It is up to the implementation how the log level is used, but log messages outside the log level should not be output.

public abstract void v (String message, Throwable t)

Logs a verbose message.
