Metric logging does not work as per the docs

[Antman261]

When I attempt to send metrics as per the docs, it attempts to JSON parse the graphite string.

in your code:

   const messages = message.map((item) => {
      if (this.config.graphite) {
        return `${item.path} ${item.value} ${Math.round(ts.getTime() / 1000)}`;
      }

conflicts with

batchReadyToSend() {
    if (this.config.batchSize === 0) {
      return this.config.interval === 0;
    } else {
      const pendingMessages = this.pendingLogs.reduce((acc, curr) => {
        const log = JSON.parse(curr);
        return acc + log.msg + '\n';
      }, '');

the code i'm calling with

const sumoLogger = new SumoLogger({
  endpoint: ENV_VARS.SumologicMetricsCollectorEndpoint,
  graphite: true,
  hostName: `WMS-${process.env.COMMIT_HASH}`,
  batchSize: 10000,
  interval: 5000,
});

sumoLogger.log({
  path: 'metric.path', // metric path as a dot separated string
  value: 100, // value of the metric
});

results in
