azure - 从 Azure Function App 将自定义跟踪消息写入 Application Insight

Question

我正在开发 Azure Function App，希望添加自定义消息/跟踪，以帮助调试和提高性能。这是我正在使用的代码:

var telemetry = new Microsoft.ApplicationInsights.TelemetryClient();
telemetry.TrackTrace("Alert Button Pressed by Device ->"+CloudObject.A, SeverityLevel.Warning,new Dictionary<string, string> { { "IoT Object", IOTMESSAGE } });

但是当我转到 Application Insight 和查询跟踪(全部)时，我没有看到我正在设置的跟踪消息。

我做错了什么吗？

我用相同的代码重现并得到了预期的结果，如下:

 [FunctionName("Function1")]
        public static async Task<HttpResponseMessage> Run([HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)]HttpRequestMessage req, TraceWriter log)
        {
            log.Info("C# HTTP trigger function processed a request.");
            string name = req.GetQueryNameValuePairs()
                .FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
                .Value;
            var telemetry = new TelemetryClient();
            telemetry.TrackEvent("Loading HomeController-Index View");          
            telemetry.TrackTrace("Alert Button Pressed by Device ->" + CloudObject.A, SeverityLevel.Warning, new Dictionary<string, string> { { "IoT Object", IOTMESSAGE } });
            if (name == null)
            {
                // Get request body
                dynamic data = await req.Content.ReadAsAsync<object>();
                name = data?.name;
            }

            return name == null
                ? req.CreateResponse(HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
                : req.CreateResponse(HttpStatusCode.OK, "Hello " + name);
        }
