      <p>A logging node with multiple log outputs using the winston, winston-elastic and winston-loki logging libraries</p>
      <h3>Details</h3>
      <p>Output <code>msg.payload</code> (or <code>msg.&lt;custom path&gt;</code>) or complete <code>msg</code> is used as input of the logged message.
      If it contains an Object it will be converted to a JSON string before being sent.</p>
      <p>The Log Level (error, warn, info, debug) used can be configured in the node or can be set
      by <code>msg.loglevel</code> (or <code>msg.&lt;custom path&gt;</code>). 
      If the content is not one of ('error', 'warn', 'info', 'debug'), 'debug' will be used as fallback</p>
      <p>If <code>msg.meta</code> is set, the meta info Object will be added to the output.</p>

      <h3>References</h3>
      <p>This node is based on parts of node-red-contrib-advance-logger</p>
