How to debug implementation as module ? Log not showing in Elasticsearch

Hi there,

I am trying top use this lib as a module but unfortunately logs are not showing in Elasticsearch and I don’t have anything displayed in my console related to this module.

Here is my code :

import * as pino from "pino";
import { multistream } from "pino-multi-stream";
const pinoElastic = require("pino-elasticsearch");

const streamToElastic = pinoElastic({
	node: "http://elastic:PASSWORD@URL:9200",
});

var streams = [{ stream: process.stdout }, { stream: streamToElastic }];

export const logger = pino({ level: "debug" }, multistream(streams)).child({ infoAddedToAllLogs: "test" });

logger.debug("Hello world");

Logs are successfully displayed in console, but unfortunately nothing related to Elasticsearch errors and nothing in Elasticsearch.

How can I debug this?

Thanks for your help

Hello! I’ve just run this code:

'use strict'

const Pino = require('pino')
const { multistream } = require('pino-multi-stream')
const pinoElastic = require('pino-elasticsearch')

const streamToElastic = pinoElastic({
  node: 'http://localhost:9200',
  index: 'logs',
  'flush-interval': 1000
})

var streams = [{ stream: process.stdout }, { stream: streamToElastic }]

const pino = Pino({ level: 'info' }, multistream(streams)).child({ infoAddedToAllLogs: 'test' })

pino.info('Hello world')

And everything works as expected. pino-elasticsearch sends the logs if either flush-bytes is reached or if flush-interval has elapsed. Unless something kills the process before flush-interval is triggered, the process will wait until all timers have been executed.

Be aware that you will not see the logs immediately in Elasticsearch because of the refresh interval.
