Promtail - error in config

1

Hi all,

I’m using loki 1.5.0 + promtail 1.5.0 + grafana 7.0.0 with three docker containers.
All worked fine for normal log files (var/log/… or apache2).
I found this interesting URL:

But when I tried to extract labels via regex out of the apache2 logs I’m getting promtail errors like

promtail_1 | Unable to parse config: /etc/promtail/docker-config.yaml: yaml: line 24: did not find expected key
promtail_1 | Unable to parse config: /etc/promtail/docker-config.yaml: yaml: line 26: mapping values are not allowed in this context

That’s my promtail-config.yaml

server:
  http_listen_port: 9080
  grpc_listen_port: 0

positions:
  filename: /tmp/positions.yaml

clients:
  url: http://loki:3100/loki/api/v1/push

scrape_configs:

 - job_name: system
   static_configs:
   - targets:
       - localhost
     labels:
       job: varlogs
       env: demo
       __path__: /var/log/*log

 - job_name: system  (I ALSO SKIPPED THIS LINE)
    pipeline_stages:
       - regex:
         expression: "^(?P<ip>\\S+) (?P<identd>\\S+) (?P<user>\\S+) \\[(?P<timestamp>[\\w:/]+\\s[+\\-]\\d{4})\\] \"(?P<action>\\S+)\\s?(?P<path>\\S+)?\\s?(?P<protocol>\\S+)?\" (?P<status_code>\\d{3}|-) (?P<size>\\d+|-)\\s?\"?(?P<referer>[^\"]*)\"?\\s?\"?(?P<useragent>[^\"]*)?\"?$"
     - labels:
         action:
         status_code:
    static_configs:
    - targets:
       - localhost
      labels:
       job: apache
       env: dev
       __path__: /var/log/apache2/access_log

I also tried ways like this:
pipeline_stages:
- match:
selector: ‘{job=“apache”}’
stages:
- regex:
expression: "above regex expression
- labels:
…

Perhaps anybody has an idea how to fix this?

Thanks, Uwe
