Multiple CosmosDB health checks always use latest connection string

[junsaw]

Please, fill the following sections to help us fix the issue

Whenever multiple CosmosDB Health Checks used with the recommendation of implementing in a SingleTon it always uses the latest connectionString. IF a Singleton is not used it results in Memory Leaks, this is new problem.

Please see sample below:

What you expected to happen:

I expect the health check to health check on both instances of the implemented singleTon

How to reproduce it (as minimally and precisely as possible):

Just add multiple CosmsoDB endpoints to check

Source code sample:

SingleTon impelementation -> Latest Connection is always used.

services.AddSingleton(sp => new CosmosClient(Configuration["Data:AzureCosmosDBGremlinConnectionString"].ToString())).AddHealthChecks() .AddAzureCosmosDB(optionsFactory: s => new AzureCosmosDbHealthCheckOptions { ContainerIds = [Configuration["Data:AzureCosmosDBGremlincollectionId"].ToString()], DatabaseId = Configuration["Data:AzureCosmosDBGremlinDatabase"].ToString() }, name: "Azure_Gremlin_CosmosDB", timeout: TimeSpan.FromSeconds(network_check_timeout));

*/

services.AddSingleton(sp => new CosmosClient(Configuration["Data:AzureCosmosDBConnectionString"].ToString())).AddHealthChecks() .AddAzureCosmosDB(optionsFactory: s => new AzureCosmosDbHealthCheckOptions { ContainerIds = [Configuration["Data:AzureCosmosDBcollectionId"].ToString()], DatabaseId = Configuration["Data:AzureCosmosDBDatabaseId"].ToString() }, name: "Azure_CosmosDB", timeout: TimeSpan.FromSeconds(network_check_timeout));

Non-SingleTon Implementaiton > Results in Memory Leaks

.AddAzureCosmosDB(sp => new CosmosClient(Configuration["Data:AzureCosmosDBConnectionString"].ToString()), sp => new AzureCosmosDbHealthCheckOptions() { ContainerIds = [Configuration["Data:AzureCosmosDBcollectionId"].ToString()], DatabaseId = Configuration["Data:AzureCosmosDBDatabaseId"].ToString() }, "AzureCosmosDB")/ / .AddAzureCosmosDB(sp => new CosmosClient(Configuration["Data:AzureCosmosDBGremlinConnectionString"].ToString()), sp => new AzureCosmosDbHealthCheckOptions() { ContainerIds = [Configuration["Data:AzureCosmosDBGremlincollectionId"].ToString()], DatabaseId = Configuration["Data:AzureCosmosDBGremlinDatabase"].ToString() }

Environment:

• .NET Core version: 8
• Healthchecks version: 8.0.1
• Operative system: Windows / Linux
