const config = {
  config: {
    resource: {
      'service.name': "anxing",
      'service.namespace': "my-namespace"
    }
  },
  spanProcessor: {
    SimpleSpanProcessor: {
      spanExpoter: {
        ConsoleSpanExporter: {}
      }
    },
    BatchSpanProcessor: {
      config: {
        /** The maximum batch size of every export. It must be smaller or equal to
         * maxQueueSize. The default value is 512. */
        maxExportBatchSize: 1,
        /** The delay interval in milliseconds between two consecutive exports.
         *  The default value is 5000ms. */
        scheduledDelayMillis: 500,
        /** How long the export can run before it is cancelled.
         * The default value is 30000ms */
        exportTimeoutMillis: 3000,
        /** The maximum queue size. After the size is reached spans are dropped.
         * The default value is 2048. */
        maxQueueSize: 10,
      },
      spanExpoter: {
        JaegerExporter: {
          host: '47.100.254.204', 
          port: 30371
        }
      }
