Azure Functions - Application Insights - Custom Telemetry - EventSource instance already exists - azure

I am trying to follow the instructions in Insights Preview where I can create custom telemetry. I followed the instructions exactly. But maybe I've got it configured wrong.
I have the APPINSIGHTS_INSTRUMENTATIONKEY set in the local.settings.json file and it seems to work fine. But when I add a new TelemetryClient I start getting those duplicate errors (below). It happens when the function gets invoked.
I really would like the telemetry data from AF to go to the same AI instrumentation key so I can see it together.
I also pulled the Microsoft.Extensions.Logging out as I wanted to use AI only, if that makes any difference.
Anyone have any suggestions?
See below...
TIA

I started over with a fresh AF project (and a glass of wine) to keep it simple.
The following code works:
private static TelemetryConfiguration config = new TelemetryConfiguration { InstrumentationKey = System.Environment.GetEnvironmentVariable("APPINSIGHTS_INSTRUMENTATIONKEY", EnvironmentVariableTarget.Process)};
private static TelemetryClient telemetryClient = new TelemetryClient(config);
This code (directly from the Preview post) does not:
private static TelemetryClient telemetryClient = new TelemetryClient();
private static string key = TelemetryConfiguration.Active.InstrumentationKey = System.Environment.GetEnvironmentVariable("APPINSIGHTS_INSTRUMENTATIONKEY", EnvironmentVariableTarget.Process);
An unfortunate side effect is that the telemetry doesn't show up in te VS2017 Application Insights window automatically. You have to use the settings gear to select the AI repository you want and then you can see it. Minutes later, but better than nothing.

Azure function 1.0 Logging

I am using azure function with ILogger to log exception and tracing in Application Insights. I use log.LogError with an exception object as a second parameter. However, whatever log it only comes under traces in app insights and doesn't logs the entire exception object. Is there a way to get exception object with the entire stack?
Also, the dependency is empty and I make multiple HTTP calls and I am expecting it to log all HTTP calls as dependency.
The LogError extension method takes the exception object as the first parameter. Give that a try and your Exception object should show up correctly in App Insights.
public static void LogError (this Microsoft.Extensions.Logging.ILogger logger, Exception exception, string message, params object[] args);

Performance testing in Dynamics 365 for Operations - no endpoint listening

Short error description:
Ms.Dynamics.Performance.CreateUsers.exe from PerfSDK throws error
There was no endpoint listening at https://mytest.sandbox.operations.dynamics.com/Services/AxUserManagement/Service.svc/ws2007FedHttp that could accept the message.
Long error description:
I have created a single user C# test from an XML recording and run it with PerfSDK successfully as described in the first part of the PerfSDK and multiuser testing with Visual Studio Online guide.
I am having trouble running multiuser load tests as described in the second part of the lab. The link above seems to be the only resource online describing how a multiuser test can be created from a singleuser test and how Visual Studio Online can be used to run it in a sandbox environment. I've also watched a few videos such as Tools to Measure and Improve Microsoft Dynamics AX Performance, Performance Tools and the like, but none of them explains all the steps that need to be taken in as much detail as the above article.
I've done the following:
Created a recording of a scenario with Task Recorder in Dynamics 365
for Operations.
Created C# perf test from recording in Visual Studio using the
PerfSDKSample project from the PerfSDK folder.
Followed all 'Steps to run single user performance test with Perf
SDK' from the article;
Built the solution and successfully ran my test from Test Explorer:
Internet Explorer opened starting and replaying the scenario that I
had recorded.
Note: I used DEV environment usnconeboxax1aos.cloud.onebox.dynamics.com for testing. When I tried using another hostname in CloudEnvironment.Config (a sandbox, e.g. mysandbox.sandbox.operations.dynamics.com), the singleuser test failed with the following error message:
System.TypeInitializationException: The type initializer for 'MS.Dynamics.TestTools.CloudCommonTestUtilities.Authentication.UserManagement' threw an exception. ---> System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at https://mysandbox.sandbox.operations.dynamics.com/Services/AxUserManagement/Service.svc/ws2007FedHttp that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: The remote server returned an error: (404) Not Found..
For multiuser testing, I launched Visual Studio from Visual Studio
Online portal https://app.vssps.visualstudio.com/profile/view
I modified the TestSetup method as follows:
Single-user TestSetup:
public void TestSetup()
{
SetupData();
_userContext = new UserContext(UserManagement.AdminUser);
Client = DispatchedClient.DefaultInstance;
Client.ForceEditMode = false;
Client.Company = "GB01";
Client.Open();
}
Multi-user TestSetup:
public void TestSetup()
{
var testroot = System.Environment.GetEnvironmentVariable("DeploymentDir");
if (string.IsNullOrEmpty(testroot))
{
testroot = System.IO.Directory.GetCurrentDirectory();
}
Environment.SetEnvironmentVariable("testroot", testroot);
if (this.TestContext != null)
{
timerProvider = new TimerProvider(this.TestContext);
}
SetupData();
_userContext = new UserContext(UserManagement.AdminUser);
Client = new DispatchedClientHelper().GetClient();
Client.ForceEditMode = false;
Client.Company = "GB01";
Client.Open();
}
I set the HostName in CloudEnvironment.Config to the sandbox URL e.g. mysandbox.sandbox.operations.dynamics.com.
Logged in to the sandbox machine and installed the certificate I had generated earlier for the single-user testing.
Updated wif.config on the sandbox machine in the same way it had been updated in DEV earlier, and restarted IIS.
Double-clicked vsonline.testsettings in Solution Explorer and used the settings recommended in the above article (accordingly modified for my certificate and test scenario).
Opened SampleLoadTest.loadtest from Solution Explorer and tweaked it to use only my test in the Test Mix node, reduced test duration and user count.
Run the load test.
The load test ended with a few errors. The first TestError is the same as mentioned above:
Initialization method MS.Dynamics.Performance.Application.TaskRecorder.GenJnlBase.TestSetup threw exception. System.TypeInitializationException: System.TypeInitializationException: The type initializer for 'MS.Dynamics.TestTools.CloudCommonTestUtilities.Authentication.UserManagement' threw an exception. ---> System.ServiceModel.EndpointNotFoundException: There was no endpoint listening at https://mysandbox.sandbox.operations.dynamics.com/Services/AxUserManagement/Service.svc/ws2007FedHttp that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details. ---> System.Net.WebException: The remote server returned an error: (404) Not Found..
Finally, even though I was able to run Ms.Dynamics.Performance.CreateUsers.exe on my DEV machine successfully (a number of test AX users were created in usnconeboxax1aos.cloud.onebox.dynamics.com), when the sandbox environment URL was set in CloudEnvironment.Config, Ms.Dynamics.Performance.CreateUsers.exe failed with same error:
C:\PerfSDK>Ms.Dynamics.Performance.CreateUsers.exe 3 GB01
Failed with the following error:

As per the walkthrough,
If you have an ARR-enabled environment, i.e. you have 2 endpoints like
this:
apr-arr8aossoap.axcloud.test.dynamics.com
apr-arr8aos.axcloud.test.dynamics.com
You would need to enter both endpoints in CloudEnvironment.Config
The no endpoint listening error can be resolved by specifying correct SOAP hostname, e.g.
<ExecutionConfigurations Key="HostName" Value="mysandbox.sandbox.operations.dynamics.com" />
<ExecutionConfigurations Key="SoapHostName" Value="mysandboxaossoap.sandbox.operations.dynamics.com" />

Azure Web App - HTTP time out

After a deploy to our Azure Web App, we are getting 500 timeouts on any request to the service:
500 - The request timed out.
The web server failed to respond within the specified time.
This has come out of the blue and we cannot determine what's causing it. It seems to take around 230s consistently to time out.
I've enabled all the diagnostic logs in the portal:
But I honestly don't quite know what to look for in the logs. I've scoured through all the files in the following folders but nothing jumps out.
How can I troubleshoot this problem?
The trick to get debug messages is to set stdoutLogFile="D:\home\LogFiles\stdout.log" in your config, instead of the ..\logs path that you had. After changing that, you get an error file under D:\home\LogFiles. Here is the error you get:
Application startup exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentNullException: SMTP server password cannot be null or empty.
Parameter name: smtpPassword
at TransitApi.Infrastructure.Modules.Logging.EmailOutput.EmailLogger..ctor(String recipient, String sender, String smtpUsername, String smtpPassword, String smtpHost, Int32 smtpPort, String environmentName, LogLevel minimumLevel)
at TransitApi.Infrastructure.Modules.Logging.EmailOutput.EmailLoggerProvider.CreateLogger(String name)
at Microsoft.Extensions.Logging.Logger.AddProvider(ILoggerProvider provider)
at Microsoft.Extensions.Logging.LoggerFactory.AddProvider(ILoggerProvider provider)
at TransitApi.Api.Startup.Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
So some kind of issue setting up the mail server. That causes the process to crash, and that it behaves poorly.
But I highly suggest that you upgrade to Core RC2, as RC1 is quite obsolete.

Unity MVC GetService In Background Thread throws NullReferenceException

As far as I know the DependencyResolver is Thread-Safe, however, running the following code throws a null reference exception in a background thread.
public interface ITest {
}
public class Test : ITest {
}
//this works fine
var service = DependencyResolver.Current.GetService<ITest>();
var t1 = Task.Run(() => {
//This throws a Null Reference exception.
// note that DependencyResolver.Current is NOT null.
// The exception occurs in GetService
var s1 = DependencyResolver.Current.GetService<ITest>();
});
Task.WaitAll(t1);
Here's the stack trace:
at Unity.Mvc4.UnityDependencyResolver.get_ChildContainer()
at Unity.Mvc4.UnityDependencyResolver.IsRegistered(Type typeToCheck)
at Unity.Mvc4.UnityDependencyResolver.GetService(Type serviceType)
at System.Web.Mvc.DependencyResolverExtensions.GetService[TService](IDependencyResolver resolver)
at System.Threading.Tasks.Task.InnerInvoke()
at System.Threading.Tasks.Task.Execute()
I'm aware that the "Service Locator" pattern is an anti-pattern. At this point I'm just trying to understand why this doesn't work.
Any insights would be appreciated.
Thanks!
From the stack trace it is clear that you are using the the Unity.Mvc4 NuGet package, which is some unofficial package and is not published by Microsoft. This package contains a bug. Its UnityDependencyResolver.ChildContainer property calls HttpContext.Current.Items without checking whether HttpContext.Current is null and it causes a NullReferenceException when instances are resolved outside the context of a web request.
So instead of using that unofficial NuGet package, I think you're better off using the official NuGet package.

MOSS 2007 site in a farm type initializer exception

We have some solution that we built against a MOSS farm one of which includes a timer job. This job has been working just fine for months. Recently the administrator enlisted another server into the farm, and our timer job automatically started running on this new machine. As soon as this switch happened our timer job started yielding the error below (found this in the SP logs).
At first I thought it was a rights issue, but the timer service on the machine where it worked before and the new one are running under the same domain account. It seems to be failing while looping the site list in a site collection, on just one of the sites/webs (code snippet below). I know that this domain account has access to this because it works on the other box under same account. Does anyone have any ideas on why this cryptic error is occurring? Or if any special procedure needs to be done on this new machine to ensure it has proper ACL's for all databases in the MOSS farm?
Code:
public static void Main(string[] args)
{
SPSecurity.RunWithElevatedPrivileges(delegate() { setInputParameters(); });
}
private static void setInputParameters()
{
SPFarm farm = SPFarm.Local;
SPWebService service = farm.Services.GetValue<SPWebService>("");
foreach (SPWebApplication webApp in service.WebApplications)
{
foreach (SPSite siteCollection in webApp.Sites)
{
using(siteCollection)
{
siteCollection.CatchAccessDeniedException = false;
try
{
/* Here is the line that it fails on */
foreach (SPWeb web in siteCollection.AllWebs)

Check the DLLs for SharePoint, do all exists and all are the same version? Try putting a catch for the TypeInitializationException, and see what is wrong inside that exception.
It's not a solution, but as a workaround in the interim, I think my suggestion to one of your other questions here:
How do you instruct a SharePoint Farm to run a Timer Job on a specific server?
will keep you running while you investigate further.
Check the NLB (Network Load Balancing) configuration. Most of the time SharePoint and applications integrated to it fails when NLB changes its state. There is a patch available to solve this problem. Just a suggestion. Not sure if this is the reason. But I have faced a similar issue and the root cause was an NLB bug
A Type init exception just means an exception occurred in the .ctor of the class (as you probably know). The real exception should be in the InnerException property - can you get your hands on this? Likely it's stemming from the database alright, from Microsoft.SharePoint.Administration.SPPersistedChildCollection InitializeFromDatabse method.
Can you look into the sharepoint logs (on that errant server) for information about the database error, it will be there. Reading logs are a pain, but not if you install the ULS Log Viewer feature from http://www.codeplex.com/features
Since the stacktrace has SPAlternateUrl tinkering furhter up the stack, perhaps your zones are misconfigured (and do not include a mapping for this new server's machine name) - granted, it shouldn't fail this bad, but what can you do.
You can filter the ULS logs by source.
