AspNetCore.Pulse.Azure.Storage.Files.Shares 8.0.2

Azure File Storage Health Check

This health check verifies the ability to communicate with Azure File Storage. It uses the provided ShareServiceClient to get first share or configured share properties.

Defaults

By default, the ShareServiceClient instance is resolved from service provider. AzureFileShareHealthCheckOptions does not provide any specific share name, so the health check fetches just first share.

void Configure(IHealthChecksBuilder builder)
{
    builder.Services.AddSingleton(sp => new ShareServiceClient(new Uri("azure-file-share-storage-uri"), new DefaultAzureCredential()));
    builder.AddHealthChecks().AddAzureFileShare();
}

Customization

You can additionally add the following parameters:

• clientFactory: A factory method to provide ShareServiceClient instance.
• optionsFactory: A factory method to provide AzureFileShareHealthCheckOptions instance. It allows to specify the share name.
• name: The health check name. The default is azure_file_share.
• failureStatus: The HealthStatus that should be reported when the health check fails. Default is HealthStatus.Unhealthy.
• tags: A list of tags that can be used to filter sets of health checks.
• timeout: A System.TimeSpan representing the timeout of the check.

void Configure(IHealthChecksBuilder builder)
{
    builder.Services.AddSingleton(sp => new ShareServiceClient(new Uri("azure-file-share-storage-uri"), new DefaultAzureCredential()));
    builder.AddHealthChecks().AddAzureFileShare(
        optionsFactory: sp => new AzureFileShareHealthCheckOptions()
        {
            ShareName = "demo"
        });
}

Breaking changes

In the prior releases, AzureFileShareHealthCheck was a part of Pulse.AzureStorage package. It had a dependency on not just Azure.Storage.Files.Shares, but also Azure.Storage.Queues and Azure.Storage.Blobs. The packages have been split to avoid bringing unnecessary dependencies. Moreover, AzureFileShareHealthCheck was letting the users specify how ShareServiceClient should be created (from raw connection string), at a cost of maintaining an internal, static client instances cache. Now the type does not create client instances nor maintain an internal cache and it's the caller responsibility to provide the instance of ShareServiceClient (please see #2040 for more details). Since Azure SDK recommends treating clients as singletons <see href="https://devblogs.microsoft.com/azure-sdk/lifetime-management-and-thread-safety-guarantees-of-azure-sdk-net-clients/"/> and client instances can be expensive to create, it's recommended to register a singleton factory method for Azure SDK clients. So the clients are created only when needed and once per whole application lifetime.
