JSON interpretation issue with promtail

[sergiomayoral]

Hello,

I’m using flog to generate this kind of events:
“{“host”:“138.130.28.48”, “user-identifier”:”-", “datetime”:“25/Apr/2022:16:32:50 +0000”, “method”: “DELETE”, “request”: “/expedite”, “protocol”:“HTTP/1.0”, “status”:403, “bytes”:17719, “referer”: "https://www.dynamicproactive.name/models/relationships/expedite/vertical"}"
"{“host”:“236.116.30.89”, “user-identifier”:“kihn7123”, “datetime”:“25/Apr/2022:16:32:50 +0000”, “method”: “POST”, “request”: “/synergize/revolutionize/incentivize”, “protocol”:“HTTP/1.0”, “status”:301, “bytes”:3488, “referer”: “http://www.futurecross-media.com/infrastructures/applications”}
"
I’m using grafana loki with promtail to index events with this config:

`clients:

• url: http://loki:3100/loki/api/v1/push
  scrape_configs:

• job_name: flog
  static_configs:

  • targets:
    • localhost
      labels:
      job: flogs
      check: test4
      path: /tmp/log/*.log

  pipeline_stages:

  • json:
    expressions:
    datetime: datetime
    method: method
    host: host
    status: status
    bytes: bytes
    referer: referer
    `

The problem is that no field selected in the configuration is parsed.

Do you see any mistake in the configuration?

Thanks
