Hello Artium Nihamkin,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you would like to connect Cosmos Table DB to managed Grafana.
You will need to understand that Azure Cosmos DB plugin for Grafana is a closed source and only available for Grafana Enterprise which makes it a little bit tricky.
If you have access to Grafana Enterprise, you can use the Azure Cosmos DB plugin. This plugin allows you to query and visualize Cosmos DB data directly in Grafana - https://grafana.com/docs/plugins/grafana-azurecosmosdb-datasource/latest/ and you can connect your Azure Managed Grafana workspace to Azure Cosmos DB using managed private endpoints - https://learn.microsoft.com/en-us/azure/managed-grafana/how-to-connect-to-data-source-privately - this makes sure secure and private connectivity.
If you decide to host Grafana on Azure, you can still use the Azure Cosmos DB plugin if you have a Grafana Enterprise license. Alternatively, you can explore other methods such as:
- Tools like Connect Cloud can help you configure Cosmos DB connectivity for Grafana. - https://www.cdata.com/kb/tech/cosmosdb-cloud-grafana.rst
- Power BI - https://betterstack.com/community/comparisons/grafana-alternatives
- Azure Monitor
- Azure Data Explorer
