Azure SQL Data Warehouse: Troubleshoot with the Resource Health check

Azure DW Resource HealthAzure DW Resource Health2 New update for Azure SQL Data Warehouse…

Reduce troubleshooting time with the upgraded Resource Health check for SQL Data Warehouse.

This upgrade considers the health status of all components of the SQL Data Warehouse architecture, which includes each SQL database distribution and the SQL Data Warehouse engine on each compute node. Login and heartbeat signals of each component are emitted at least once every 2 minutes, providing you a low-latency, holistic view of the health status of your data warehouse. If your instance is Unavailable, we will provide the reason along with recommended actions that you should perform.

The Resource Health check can detect unavailability reasons, such as when your instance is pausing, scaling, or upgrading. This feature also detects when there are any connection issues, whether they are user connections or inner SQL database connections.

You check the health of SQL Data Warehouse by signing in to the Azure portal and clicking the Resource Health blade.

RESTful interactions with Azure Cosmos DB resources using the DocumentDB API, CRUD operations, API for MongoDB and additional quick starts

Azure Cosmos DB is a globally distributed system that supports the document, graph, and key-value data models which Microsoft have classified as a multi-model database service for mission-critical systems.

It also supports both the API for MongoDB and the DocumentDB API for creating, querying, and managing resources.

If you would like to understand how to answer any of the following questions: –

  • How do the standard HTTP methods work with Azure Cosmos DB resources?
  • How do I create a new resource using POST?
  • How do I register a stored procedure using POST?
  • How does Azure Cosmos DB support concurrency control?
  • What are the connectivity options for HTTPS and TCP?

Then take a look at Azure Cosmos DB REST API for full details first published on 18th July 2017 which covers these topics.


If interested in performing CRUD operations using REST, see Common tasks using the Azure Cosmos DB REST API.


If interested in performing CRUD operations using C# and REST, see the REST from .NET Sample on GitHub which can help you out.


If interested in more details of the MongoDB API, then see Introduction to Azure Cosmos DB: API for MongoDB which covers the benefits of using Azure Cosmos DB for MongoDB applications.

Querying Azure Cosmos DB resources using the REST API

Cosmos DB REST API Query
Azure Cosmos DB is a globally distributed multi-model database with support for multiple APIs. This is a link to an article which describes how to use REST to query resources using the Azure Cosmos DB API – https://docs.microsoft.com/en-us/rest/api/documentdb/querying-documentdb-resources-using-the-rest-api

All Cosmos DB resources (with the exception of account resources) can be queried using Azure Cosmos DB SQL language. See Query with Azure Cosmos DB SQL for additional details on syntax – http://azure.microsoft.com/documentation/articles/documentdb-sql-query
