feat(nodejs): add logger sdk, fix metrics and update some packages

[pragmaticivan]

fixes #1458

[martinkuba]

It looks to me like the sdk-logs package is missing in the package.json file.

Good catch @martinkuba , just realized one my changes didn't go through

[pragmaticivan]

Hi @martinkuba @tylerbenson is there a way to release an alpha version of this layer for some manual tests?

[tylerbenson]

I'm not sure what the process is, but I believe you can publish the layer to your own account and test from there.

I have this working on my own account for Metrics and Tracing already, checking logs

[pragmaticivan]

I now have Logs, Tracing, Metrics, and Tracing correlation with Logs working!

Log code:

const otelLogger = logsAPI.logs.getLogger('default');
  otelLogger.emit({
    severityNumber: logsAPI.SeverityNumber.INFO,
    severityText: 'INFO',
    body: 'this is a log record body - test on new build',
    attributes: { 'log.type': 'LogRecord' },
  });

Also tested producing logs with Winston Transport

👋🏽 @tylerbenson do you think we can release this change this week?

[pragmaticivan]

Hi @tylerbenson mind approving the last merge test run? there was a conflict with the other PR merged yesterday

[serkan-ozal]

LGTM!

One question: Does enabling logging exporter mean that console log methods (log, trace, debug, info, error, ...) are automatically patched/wrapped and all console logs are exported by default?

[pragmaticivan]

@serkan-ozal no, your own lib has to be compatible with the OTEL SPEC, OR you have to manually emit logs using the OTEL Logs API:

const otelLogger = logsAPI.logs.getLogger('default');
  otelLogger.emit({
    severityNumber: logsAPI.SeverityNumber.INFO,
    severityText: 'INFO',
    body: 'this is a log record body - test on new build',
    attributes: { 'log.type': 'LogRecord' },
  });

In my example, my project was using winston, so I just had to add https://github.com/open-telemetry/opentelemetry-js-contrib/tree/main/packages/winston-transport so that my existing logging lib can also emit otel resources automatically
