Phenix Web SDK

Using logger functionality

Phenix Web SDK gives a lot of possibilities to manage the logging functionality. You can set the level of logging. Turn logging of or manage the level of logging for different type of log appenders.

Manage logging functionality on pre-init

Turn off logging

There are multiple ways to turn off logging. To turn off logging, you can add a meta tag to the head of the web page that loads the SDK:

    <meta name="phenix-logging-level" value="Off"/>

Or if you want to turn off only logging to the console, you can specifically disable the console logger:

    <meta name="phenix-console-logging-level" value="Off"/>

For debugging purposes, you can enable URI parameter parsing which enables you to control logging via URI parameters. To turn off logger from query parameter:

    <meta name="phenix-logging-level-uri-parmeter-name" value="logLevel"/>

And then add the query parameter to the URL ?logLevel=Off. Or turn off only console.log functionality of the logger:

    <meta name="phenix-console-logging-level-uri-parameter-name" value="consoleLogLevel"/>

And then add the query parameter to the URL ?consoleLogLevel=Off

Controlling the log levels

The same way you control disabling logs, you can use to set the custom log threshold with the following levels:

  All,
  Trace,
  Debug,
  Info,
  Warn,
  Error,
  Fatal,

If you set All, you will get all logs. If you set Info, you will get Info and all logs with higher severity: Warn, Error, Fatal. Example setting the log threshold to Error and higher severity:

For all log appenders

    <meta name="phenix-logging-level" value="Error"/>

Or using query parameters:

    <meta name="phenix-logging-level-uri-parmeter-name" value="logLevel"/>

And then add the query parameter to the URL ?logLevel=Error

Specifically for the console log appender

    <meta name="phenix-console-logging-level" value="Error"/>

Or using query parameters:

    <meta name="phenix-console-logging-level-uri-parameter-name" value="consoleLogLevel"/>

And add query parameter to the url consoleLogLevel=Error

Manage logging functionality after pre-init

Turn off logging

To turn of logging after pre-init, you can use SDK.init function:

    phenix.SDK.init({
        loggingLevel: 'Off'
    });

Or if you want to turn off only logging to the console, you can specifically disable the console logger:

    phenix.SDK.init({
        consoleLoggingLevel: 'Off'
    });

Controlling the log levels

For all log appenders:

    phenix.SDK.init({
        loggingLevel: 'Error'
    });

Specifically for the console log appender:

    phenix.SDK.init({
        consoleLoggingLevel: 'Error'
    });

Setting different levels for the console log appender and other appenders:

    phenix.SDK.init({
        loggingLevel: 'Info',
        consoleLoggingLevel: 'Error'
    });
