High Network usage - SqlServer storage

[dbarwikowski]

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

What happened: I've noticed that my application is using ~20MB/s of network bandwidth. It pulls tons of data from sql server DB. Not sure why it needs to pull so much data every second. After changing from SqlServerStorage to SqliteStorage problem disappeared.

What you expected to happen: I have 10s delay between healthchecks. I would assume, that reads/writes would happen less often.

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

Source code sample:

            services.AddHealthChecksUI(setup => {
                setup.SetHeaderText($"Health of [{Environment.MachineName}]");
                setup.AddHealthCheckEndpoint($"{Environment.MachineName}", $"http://{Environment.MachineName}/MyAPI/healthz");
            })
                //.AddSqlServerStorage(configuration.GetConnectionString("dbConnection"));
                .AddSqliteStorage($"Data Source=HealthChecksUI.db");

Anything else we need to know?: HealthChecks-UI and tested application are the same application.

Environment:

• .NET Core version: netcoreapp3.1
• Healthchecks version:
  • AspNetCore.HealthChecks.UI 3.1.3
  • AspNetCore.HealthChecks.UI.Client 3.1.2
  • AspNetCore.HealthChecks.UI.SQLite.Storage 3.1.2
  • AspNetCore.HealthChecks.UI.SqlServer.Storage 3.1.2
• Operative system: Windows Server 2016
• Others:

On the same server we have other .net applications and their network usage is 50x smaller.

Server setup causes this behavior - cannot reproduce on other devices
