Sorry to see this! However, I don't see any metric sink being configured - Can you add one please?
https://promitor.io/configuration/v2.x/runtime/scraper#metric-sinks

Just so you know, there is a newer version of Promitor if you want to give it a go.

[ggustin]

Sure, here you go:

version: v1
metricDefaults:
  aggregation:
    interval: 00:05:00
  scraping:
    # Every minute
    schedule: "0 * * ? * *"
runtime:
  metricSinks:
    prometheusScrapingEndpoint:
      enabled: true
      baseUriPath: /metrics
      enableMetricTimestamps: True

[tomkerkhove]

Note that you'll need to remove the runtime as this is not how it is configured:
https://promitor.io/configuration/v2.x/runtime/scraper

[ggustin]

Thank you very much. I got confused among all possible configurations

[tomkerkhove]

No problem, feel free to let me know what the outcome is.
