Hi,
I am finding difficult to create the scrape config that can create labels “sec,min,hr,month,year”.I am using the helm chart grafana/promtail and trying to add some code in the extraScrapeConfigs.
below is the code we have implemented in instances and now we are looking to use in K8.

scrape_configs:
- job_name: logs
  pipeline_stages:
  #- timestamp:
  #    source: time
  #    format: RFC3339
  - regex:
      expression: ^(?P<timestamp>\[[^\]]*])
  - regex:
      expression: (?P<year>\d{4})-(?P<month>\d{2})-(?P<date>\d{2})\ (?P<hour>\d{2})
      source: “timestamp”
  - labels:
      year:
      month:
      date:
      hour:

Please suggest any modifications we may do in the above code to create “sec,min,hr,month,year” labels.
Thanks in Advance.

Hi @dkumarkaran ,

I can’t help you with your question but I would like to point out that high cardinality labels like this are strongly discouraged.
