To Reproduce

1. Promtail 1.5.0 binaries from releases on github

Config

server:
  grpc_listen_port: 9095
  http_listen_port: 9080

positions:
  filename: /var/log/promtail.positions.yaml
clients:
  - url: http://127.0.0.1:3100/loki/api/v1/push

scrape_configs:
  - job_name: logfile
    pipeline_stages: []
    static_configs:
    - labels:
        __path__: /var/log/{,*/}{*[._]log,{mail,news}.{err,info,warn}}
        host: host
        job: logfile
      targets:
      - localhost

Expected behavior
entry_parser is not used. I do not expect this message.

Thanks for reporting this @j0ju, I noticed too that I was seeing this in the logs and hadn't looked very closely, seems like a bug has slipped in here displaying this warning when it shouldn't be there!

[vsile]

I have the same issue.

This issue has been automatically marked as stale because it has not had any activity in the past 30 days. It will be closed in 7 days if no further activity occurs. Thank you for your contributions.

I am seeing this behavior as well with v1.6.1. Nowhere in my config is the entry_parser option being used.

https://grafana.com/docs/loki/latest/clients/promtail/configuration/#scrape_config

should be

- job_name: grafana
  pipeline_stages:
    - docker: {}
  static_configs:
  - targets:
      - grafana
    labels:
      job: grafana
      __path__: /usr/local/var/log/grafana/grafana.log

iow at least one key is required and that will make the warning stop
