  • Find causes and solutions for service unavailable exceptions. See documentation.

Troubleshoot query issues for Azure Cosmos DB API for MongoDB

Monitoring Azure Cosmos DB database operations

  • You can gather server-side metrics about the data stored in Azure Cosmos DB using tools in the Azure portal or Azure Monitor, or by using the .NET, Java, Python or Node.js SDKs. See documentation.
  • Performance and availability can also be monitored with a reference of log and metric data. See documentation.

Use the Azure Cosmos DB .NET SDK to define a group of point operations that must succeed or fail together in order to be committed. See documentation.

Migrate v1 .NET applications to v2 .NET SDK

The Azure Cosmos DB .NET SDK v1 will be retired. You can enjoy new features and functionality by migrating your applications to the Azure Cosmos DB v3 .NET SDK.  You can also move to v2 if you’d prefer. See documentation.
