Expected Behaviour

echo "GET http://localhost/" | vegeta attack -duration=15m -prometheus-addr 0.0.0.0:9090 command works fine. I can see the prometheus stats in the browser. But the Grafana integration is failing.

Actual Behaviour

While trying to add Prometheus data source in Grafana showing below error.

Steps to Reproduce

1. Install vegeta
2. Install grafana
3. Run vegeta w/ prometheus flag
4. Add prometheus datasource in Grafana

Additional Context

grafana version 10.2.0

That seems like an issue between Grafana and Prometheus. Or am I misunderstanding?

[QAInsights]

Yes, that's correct. I reinstalled everything starting from scratch. Started the test in vegeta. But the dashboard is blank.

But the Grafana dashboard looks empty.

Prometheus data source

It seems that adding the -prometheus-addr is not pushing any data to prometheus, I wonder why would that be.
