kandi X-RAY | StatusMonitor Summary
HealthMonitor is a sample of OpenCL multi-GPU application exercising the GPUs by executing 3 OpenCL featured kernels. The GPU devices IDs to be tested are defined by the "-iDD" parameter, and the number of times the kernels are executed is defined by the "mode" parameter value. Program options: -m mode mode=0 perform 31 iterations, mode=1 perform 310 iterations, mode=2 perform 2000 iterations. -iDD Id0,...,Idn comma separated list of GPU device Ids.

QUESTION
I'm using Azure Application Insights on the free tier. We also use amazon AWS health checks that hits a pre-determined page expecting a 200 response it then does things if it gets a different response.
All the requests from AWS are filling up telemetry pretty quickly.
Is there a simple way to filter or exclude these requests?
Can it be done from the App Insights console, or does it require modifying the telemetry collector on the actual application. I'd rather not create my own implementation of the ITelemtryProcessor...
And if i am stuck going that route, would this work to filter AWS Route53 checks?
...ANSWER
Answered 2017-Sep-13 at 18:22You'll have to write a telemetry initializer like you have above.
However, you might want to look more specifically at the synthetic source and verify content and only throw away the amazon health checks instead of all synthetic traffic (you could also look at request name, etc to make your decisions), as i'm not exactly sure what information is in those inbound requests from amazon.
Otherwise, you might be throwing away incoming requests/dependencies/exceptions that might occur from your webtests, which would also show up as synthetic.

QUESTION
We have an application which is based on micro services architecture and we have enabled application insights for the application. We have multiple asp.net Web APIs which call each other and also are called from angular based UI. Currently we are able to trace all the telemetry through Operation Id which is constant or same for all telemetry. Till here everything works fine . But next we want to enable hierarchical correlation so that we can know when a Request is triggered what all other requests / dependencies it is triggering and if there are any exceptions which request caused it .
What I want to know is if this is enabled by default (below I have given my applicationinsghts.config) or is there a step by step guide telling what are the steps we need to follow to enable this kind of correlation.
I have already gone through most of the documentation which is on MSDN and other resources and understand conceptually how it works but I am not able to find a code sample or example which does this for a setup like us.

QUESTION
I have an Azure Cloud Service with a single worker role that will deploy, start, and run without fail every time, but I ran into some intermittent problems I wanted to diagnose with Application Insights. I followed directions from this article as well as here.
After installing the nugget packages and adding the one line of code, I ran the cloud service locally in both debug and release mode, and was able to see the AI info being reported to the Application Insights resource. So I packaged it up and uploaded the new configuration to my cloud service.
But then from the cloud the worker role will not actually start--it goes into a recycle death spiral, and in the "Diagnose and Solve Problems" blade I get a variation of the error below, always about "System.Threading.AsyncLocal'1'" and not being able to load the RoleEntryPoint. Following this article did not shed much light onto things, as the error pretty much tells me why it keeps recycling but not any clues on what to do about it.
Production - WebReportDownloader_IN_0: BusyRole Waiting for role to start... Failed to load role entrypoint. System.TypeLoadException: Could not load type 'System.Threading.AsyncLocal`1' from assembly 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. at Microsoft.ApplicationInsights.Extensibility.SdkInternalOperationsMonitor.Exit() at Microsoft.ApplicationInsights.Extensibility.Implementation.TelemetryConfigurationFactory.Initialize(TelemetryConfiguration configuration, TelemetryModules modules, String serializedConfiguration) at Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration.get_Active() at WebReportDownloader..ctor() in C:\Users\User\Source\Repos\Program\WebReportDownloader\WebReportDownloader.cs:line 21 --- End of inner exception stack trace --- at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark) at System.Activator.CreateInstance(Type type, Boolean nonPublic) at System.Activator.CreateInstance(Type type) at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.GetRoleEntryPoint(Assembly entryPointAssembly) at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.CreateRoleEntryPoint(RoleType roleTypeEnum) at Microsoft.WindowsAzure.ServiceRuntime.RoleEnvironment.InitializeRoleInternal(RoleType roleTypeEnum) [2017-09-14T15:28:21Z] Last exit time: [2017/09/14, 15:28:21.944].

Normally I can get enough of a hint from searching the exception and/or details, but this time I can't find anything that resembles my problem. All I can guess is that something small but critical is awry with my configuration, but I haven't been able to determine where I've gone off the rails based on the instructions I linked above.

I have setup AppllicationInsights resource in Azure portal. There are 2 services writing to it: windows service on premise and service fabric service running on a local service fabric cluster. I am using TelemetryClient object in both services to send data to the Azure ApplicationInsights resource. It looks like I am getting all messages I wanted, but there are some messages origin of which I don't understand. Here is example of the strange message:

...ANSWER
Answered 2017-Jul-28 at 21:59if it is a Azure Web App, only a subset of the perfcounters are exposed by Azure, they are somewhat documented here:
If you're controlling the server, you need to make sure that whatever user is running that IIS website / app pool is a member of Performance Monitor Users group so that it can read the perf counters.
These messages are coming out from the default configuration of the PerfCounterCollector package, which is included by the WindowsServer package, which you can see here at the github source for the perf counter collector
if you aren't using performance collector stuff at all and just want that to all go away, you can remove the entire
QUESTION
When changing some of the configuration settings of a webrole, the RoleEnvironment.Changing event is triggered. As far as I understand it, if Cancel is set to false in the RoleEnvironmentChangingEventArgs, the role should not recycle and the changes are just accepted and should be applied as soon as the RoleEnvironment.Changed event fires.
However, our roles are recycling despite setting Cancel to false.
This is the content of the event handler:

Answered 2017-May-25 at 18:32Any process running on the VM which hooks into the service runtime can trigger a recycle. Check WaHostBootstrapper logs to see which process is causing the recycle.
