Why am I not seeing data in my Grafana OpenTelemetry dashboard?

Context When viewing OpenTelemetry metrics in Grafana, you may encounter situations where the dashboard appears empty or shows no data over a specified time period. This usually occurs when viewing the explore view without any specific query parameters selected. Answer If you're not seeing any data in your Grafana OpenTelemetry dashboard, ensure that you have selected appropriate query parameters. An empty query without any parameters will not return any data as the scope is too broad. To see data in your dashboard: Navigate to your Grafana explore view Select your data source (e.g., "duplo-metrics" for metrics or "duplo-logging" for logs) Add specific query parameters to filter your data. For example: Select specific metrics you want to monitor Add relevant filters like node, namespace, or service name Specify the time range for your query Run the query to view the filtered results Once you've added the appropriate query parameters, you should see the relevant metrics data displayed in your dashboard.
