Welcome @pkmcnc

I think you are confusing Alloy with a datasource, such as Prometheus.

Looks like you successfully installed Alloy on your Linux server without any issues. Great! It would appear that you are sending the metrics to Prometheus hosted in Grafana Cloud and the logs to Loki hosted in Grafana Cloud, correct?

So in Grafana, have you added the datasources of Prometheus (in Grafana Cloud) and Loki (in Grafana Cloud)? If you add them successfully, you should see your metrics and logs being scraped by Alloy in those datasources.

Hi @grant2
Thanks a lot for your reply!
Everything is working now.
Still, “Test Alloy connection” failed until I set up integrations. After that everything went smooth.
The same happened with the second server. So probably something is wrong with that test.
