How to connect a metrics/logs/traces data source from another Observability Instance

Following tutorial explains how to connect

• metrics (Thanos)
• logs (Loki)
• traces (Tempo) data source from one Observability instance into another.

Get URL of data source

1. Login to STACKIT Portal
2. Choose the Observability Instance where you like to get the data source from
3. Open Service Dashboard and select API tab.
4. Copy the relevant URL, e.g. for Thanos: https://storage.api.stackit....

Create credentials

Next step is to create credentials to access your data source.

1. Choose the Observability Instance where you like to get the data source from
2. Create new credentials
3. Note username and password.

Setup new data source within Grafana

1. Choose the Observability Instance where you like setup the new data source
2. Login to Grafana and select Connections from the toogle menu
3. Choose Data sources and after that click on Add new data source
4. Select correct data source type:
   1. for Thanos choose Prometheus
      
   2. for Loki it’s Loki
   3. for Tempo it’s Tempo
