Help wanted: How do I integrate it with express-pino-logger

[usama-dev]

I am using express-pino-logger and want to log the http and routes logs to elasticsearch using this module.

Can you please provide an example for such case?

Thanks.

Just pipe the two processes.

This is how I am doing it:

const streamToElastic = pinoElastic({
    index: 'an-index',
    type: 'log',
    consistency: 'one',
    node: 'http://localhost:9200',
    'es-version': 6,
    'bulk-size': 200,
    ecs: true
})
const logger = pino({ level: 'info' }, streamToElastic)

var myLogger = function (req, res, next) {
    logger.info(loggerHttp(req,res))    // This does not work
    req.logger = logger;
    next()
}
app.use(myLogger)

app.get('/demo', (req, res, next) => {
    req.logger.info('Route Log!')   // This works
    res.send('demo')
})

These are the records saved in ES:
{
  "took": 3,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 2,
    "max_score": 1.0,
    "hits": [
      {
        "_index": "an-index",
        "_type": "log",
        "_id": "BQURU3ABd7Iq_pY3IBo_",
        "_score": 1.0,
        "_source": {
          "ecs": {
            "version": "1.0.0"
          },
          "@timestamp": "2020-02-17T12:13:15.459Z",
          "message": "Route Log!",
          "log": {
            "level": 30
          },
          "host": {
            "hostname": ""
          },
          "process": {
            "pid": 23332
          }
        }
      },
      {
        "_index": "an-index",
        "_type": "log",
        "_id": "BAURU3ABd7Iq_pY3IBoR",
        "_score": 1.0,
        "_source": {
          "ecs": {
            "version": "1.0.0"
          },
          "@timestamp": "2020-02-17T12:13:15.448Z",
          "log": {
            "level": 30
          },
          "host": {
            "hostname": ""
          },
          "process": {
            "pid": 23332
          }
        }
      }
    ]
  }
}

This is the HTTP log I get in terminal and want this in ES too:
`{"level":30,"time":1581941935630,"pid":23332,"hostname":"","req":{"id":2,"method":"GET","url":"/demo","headers":{"host":"localhost:4000","user-agent":"insomnia/7.1.0","x-access-token":"123","content-type":"application/json","accept":"*/*","content-length":"192"},"remoteAddress":"::1","remotePort":61463},"res":{"statusCode":200,"headers":{"x-powered-by":"Express","access-control-allow-origin":"*","content-type":"text/html; charset=utf-8","content-length":"4","etag":"W/\"4-ieSV55Qc+eQOaYDRSha/AjzNTJE\""}},"responseTime":6,"msg":"request completed","v":1}`

what is loggerHttp?

If it's pino-http, you need to pass the the pino logger to pino-http: https://github.com/pinojs/pino-http#examples.
