Unable to scrape metrics using Victoriametrics VMServiceScrape

Hello,

Our Grafana setup utilizes VictoriaMetrics, a Prometheus-compatible system. I’m currently attempting to scrape the metrics exposed on /service/metrics/prometheus, but encountering login issues resulting in a 500 error. Below, you’ll find the configuration for the vmservicescrape component I’m using, along with the documentation I’ve referenced. Your prompt assistance would be greatly appreciated. Thank you.

  jobLabel: nxrm
  namespaceSelector:

Is the 500 error from Nexus? If so, is there a stack trace?

I suppose the authentication process isn’t functioning properly. Consequently, logging in isn’t possible, and the metrics aren’t being displayed. Is there an alternative method we can use for logging in, such as using a bearer token?
