Introduction

This is a quick page to note about setup of Grafana

CA Cert

The CA Cert is configured against the datasource. You cut and paste the rootCA.pem. Otherwise you get the error

client: failed to call resources: error querying resource: Post \"https://192.168.1.220:9090/api/v1/labels\": tls: failed to verify certificate: x509: certificate signed by unknown authority
