I created my free account on grafana cloud and would like to monitor my underlying Linux OS. Installed Node exporter and prometheus on my linux OS and both are running. When adding this prometheus as datasource I am getting below error:
Post "http://127.0.0.1:9090/api/v1/query": dial tcp 127.0.0.1:9090: connect: connection refused - There was an error returned querying the Prometheus API.
Is there anything I am misssing ?
