loki_distributor_lines_received_total are not equal to loki_client_lines

[Shin-Taiwan]

I am using Grafana xk6 to do the writing loading test.
The metrics loki_distributor_lines_received_total exposed by Loki Distributors are not equal to loki_client_lines exposed by xk6.

P.S there is not any error in Loki components
My Javascript

import { check, fail } from 'k6';
import loki from 'k6/x/loki';

const HOST = "localhost:3100";

const TENANT_ID = "my_org_id"

const BASE_URL = `${TENANT_ID}@${HOST}`;

const KB = 1024;
const MB = KB * KB;

const labelCardinality = {
  "app": 1,
  "namespace": 1,
};
const timeout = 10000; // 10s
const ratio = 0.9; // 90% Protobuf
const conf = new loki.Config(BASE_URL, timeout, ratio, labelCardinality);
const client = new loki.Client(conf);

/**
 * Entrypoint for write scenario
 */
export function write() {
  let streams = randomInt(10, 10);
  let res = client.pushParameterized(streams, 1 * MB, 2 * MB);
  check(res,
    {
      'successful write': (res) => {
        let success = res.status === 204;
        if (!success) console.log(res.status, res.body);
        return success;
      },
    }
  );
}

/**
 * Return a random integer between min and max including min and max
 */
function randomInt(min, max) {
  return Math.floor(Math.random() * (max - min + 1) + min);
}

./k6 run -vus 10 --duration 60s script.js

Fixed with #54
