Using pino logger with ECS format does not log custom attributes

Hi @ibadb, thanks for the question.

The pino Logger constructor doesn't accept a third argument, so your first example can't work.

To set options.name along with the pino options created by @elastic/ecs-pino-format, you will need to merge the two sets of options together and pass them to pino(). Something like this should work:

const pino = require('pino')
const ecsPinoFormat = require('@elastic/ecs-pino-format')
const log = pino({ name: 'myName', ...ecsPinoFormat() })
log.info('hi')

Running that results in:

% node play-pino.js
{"log.level":"info","@timestamp":"2022-06-02T21:18:51.563Z","process":{"pid":59472},"host":{"hostname":"pink.local"},"log":{"logger":"myName"},"ecs":{"version":"1.6.0"},"message":"hi"}

Please let me know if I've misunderstood your question.
