Question

我有一个自定义的AI Telemetry Initializer。最近，我开始收到编译器警告，说Context.Properties已过时： “ TelemetryContext.Properties已过时。请使用GlobalProperties设置全局级别的属性。对于项目级别的属性，请使用ISupportProperties.Properties。 1.我该怎么做？使用ISupportProperties.Properties？ 2.我正在根据请求记录委托人中的声明中的租户ID和deviceID。该应用程序是全球性的还是支持性的？

    public class JsonTelemetryInitializer : ITelemetryInitializer
    {
        private readonly IHttpContextAccessor _httpContextAccessor;
        private readonly SystemOptions _systemOptions;

        /// <summary>
        /// Constructor
        /// </summary>
        /// <param name="accessor">For accessing the http context</param>
        /// <param name="systemOptions">System options</param>
        public JsonTelemetryInitializer(IHttpContextAccessor accessor, IOptions<SystemOptions> systemOptions)
        {
            _httpContextAccessor = accessor;
            _systemOptions = systemOptions.Value;
        }

        /// <summary>
        /// Initialize the custom telemetry initializer
        /// </summary>
        /// <param name="telemetry">Telemetry</param>
        public void Initialize(ITelemetry telemetry)
        {
            if (_httpContextAccessor.HttpContext == null)
            {
                return;
            }

            if (_httpContextAccessor.HttpContext.User.Identity.IsAuthenticated)
            {
                const string tenantId = "northstar_tenantid";
                if (!telemetry.Context.Properties.ContainsKey(tenantId))
                {
                    var user = _httpContextAccessor.HttpContext.User;
                    telemetry.Context.Properties[tenantId] =
                        ClaimsHelper.GetClaim<int>(user, TokenNames.TenantId).ToString();

                    var userId = ClaimsHelper.GetClaim<int>(user, TokenNames.UserId).ToString();

                    telemetry.Context.Properties["northstar_userid"] = userId;
                    var deviceId = ClaimsHelper.GetClaim<string>(user, TokenNames.DeviceId);
                    if (deviceId != null)
                    {
                        telemetry.Context.Properties["northstar_deviceid"] = deviceId;
                    }

                    telemetry.Context.User.Id = userId;

                    var sessionId = ClaimsHelper.GetClaim<string>(user, TokenNames.SessionId);
                    if (!string.IsNullOrEmpty(sessionId))
                    {
                        telemetry.Context.Session.Id = sessionId;
                    }
                }
            }
        }
    }

Answer 1

1。我该怎么做？使用ISupportProperties.Properties？

只需将ITelemetry投射到ISupportProperties。

我的示例代码如下：

  using Microsoft.ApplicationInsights.Channel;
  using Microsoft.ApplicationInsights.DataContracts;
  using Microsoft.ApplicationInsights.Extensibility;

  public class MyTelemetryInitializer:ITelemetryInitializer
  {

     public void Initialize(ITelemetry telemetry)
     {
          //cast ITelemetry to ISupportProperties
          ISupportProperties propTelemetry = (ISupportProperties)telemetry;

          if (!propTelemetry.Properties.ContainsKey("isuport_key"))
          {
              propTelemetry.Properties.Add("isuport_key", "isupport_value");
          }

      }
  }

然后在执行后，该属性显示在azure门户中，屏幕截图如下：

2。我正在按请求记录委托人中的声明中的租户ID和deviceID。该应用程序是全球性的还是支持性的？

根据我的理解，您可以使用支持属性（项目级别），因为它与您之前使用过的telemetry.Context.Properties["northstar_deviceid"] = deviceId;

类似

Answer 2

我遇到了类似的问题并找到了这篇文章。他们添加了用于向 TelemetryContext 添加属性的文档。只需将 ITelemetry 转换为 RequestTelemetry。

public void Initialize(ITelemetry telemetry)
{
    var requestTelemetry = telemetry as RequestTelemetry;
    
    if (requestTelemetry == null) return;

    requestTelemetry.Properties["customProp"] = "test";
}
