Application labels best practices, `app` vs `app_name` vs `job` vs `service_name`


I’m trying to get more familiar with loki (and faro).

I’m struggeling a bit to find a best practice for “the name that tells me what application or service it is”.

I saw several examples that used either job or app.
Then there is grafana faro that adds app_name into the log.

And in opentelemtry they refer to it as so I guess service_name could also be valid choice.

Does anyone has some pointers to common best practices when it comes to this label?

Kind Regards,

I posted this already in grafana faro’s github discussion but it seems pretty dead so I dared a cross post, sorry :slight_smile:
