[paymentservice] Adds otel logging support

[Kimbohlovette]

This PR adds otel instrumentation of the pino library to the payment service

[julianocosta89]

Hello @Kimbohlovette,

I've tested this PR and couldn't see any logs being exported via OTLP.

I do see trace data being added to the logs, but the logs are not being sent to the collector.

[Kimbohlovette]

Okay, similar thing as with the accounting service. Any recommendations on what to do?

[Kimbohlovette]

@puckpuck I've just reformatted the require statements as you requested. Could you take a look?

[Kimbohlovette]

@puckpuck @austinlparker @julianocosta89 is there a library or a stable exporter for javascript that can be used to export logs to opentelemetry?

[julianocosta89]

I spoke with @Kimbohlovette today and asked him to reach out to the otel-js team and check if the OTel logs are actually usable.
Whenever he gets a reply, he will either adjust this PR to properly export the logs, or close it as not implemented yet.

I answered on Slack as well, but for the record here: the OTel JS package @opentelemetry/instrumentation-pino does not yet support the logs bridge API for sending log records via OTLP. I intend to work on that, but haven't gotten to it yet. (FWIW, the other instrumentation JS logging framework instrumentations -- Bunyan and Winston -- have added logs bridge support recently.)

[Kimbohlovette]

@julianocosta89 I've done discussed with trentm I will use bunyan to implement this. So work is in progress

[Kimbohlovette]

@trentm @julianocosta89 I have replaced pino with bunyan and done the neccessary instrumentation.
I would like you to test and check if logs and coming to otel correctly. And I would also like to ask if checking these logs in opentelemetry is something that I can do locally before I push

[julianocosta89]

@Kimbohlovette you can build this service locally and then start the demo locally.
Once everything is up and running, you can navigate to grafana:
localhost:8080/grafana and check if the logs are arriving in the demo chart.

Okay I am on it

[Kimbohlovette]

@julianocosta89, I've updated the environment variables. I would like you to look at the instrumentation.
Aside from that I looked at the log api which is currently in experimental and it looks like something that can work fine if we we want to keep things simple

[julianocosta89]

@Kimbohlovette could you keep the same indentation we had before?

It would make our life as reviewers easier

[Kimbohlovette]

okay

[Kimbohlovette]

okay

We would like to have OTLP logs, if it works we will definitely get it merged.

Okay

[Kimbohlovette]

I've made the requested changes

Please update your IDE settings to not modify the indentation and line wrap of code files. This will make reviewing the PR much easier.

I ran this branch, and did not see the traces or logs being emitted from the payment service. With a quicker look I noticed you added console exporters for both. I don't think you need any exporter, since the default should be OTLP, which is configured using environment variables.

Alright, I've been finding where in vscode I can disable the automatic formatting on vscode for some time now

Hello @pichlermarc, I have tried to use @opentelemetry/sdk-logs in this service to send logs to open telemetry, Unfortunately I can not see any logs emitted on grafana.
Please can you look at my code to see what is not right?

[Kimbohlovette]

@trentm I tried bunyan but no lock too

Looking at this PR's diff, it looks like there's no exporter configured other than the console log exporter. Are you using a different set of changes to export to grafana/loki? 🤔

I don't have full understanding on how the logs gets to grafana dashboard but what I understand is that in this exercise open telemetry has already been configured to send logs to grafana (which is one of the servies in this app serving on 8080/grafana).

So the goal of this issue is to get the each service to send logs to open telemetry and then it will show on grafana under the current service

hi guys, is there any news on that? I also want to enable logging in the payment service.
