Tracing Openstack Mitaka - profiling

I'm trying to trace services in Openstack Mitaka using osprofiler, but i'm having some issues. It seems it's not possible to trace nova service in Mitaka using osprofiler (correct me if i'm wrong). So i was thinking of using Zipkin.
Can anyone tell me if Zipkin integrates with openstack mitaka?

OpenStack does not have Zipkin as an inbuilt tracer. Hence OSProfiler was adopted as a standard project for tracing in OpenStack.
As far as i can see from the documentation, Nova should have OSProfiler support for Mitaka. Although i have not used OSProfiler with Mitaka, I have worked with OSProfiler with Newton and subsequent releases.
You can post the issue that you are facing so that it will be easier to debug.

Google Cloud Platform: Cloud Monitoring API errors showing in metrics

I seem to be getting around 30% errors related to:
google.monitoring.v3.MetricService.CreateTimeSeries
In The Cloud Monitoring API Metrics dash.
Any idea what could be causing this? As far as I know I am using the default install, having only at one time manually installed StackDriver on Debian 9. I have no idea how to interrogate the cause of these errors and where to do so in order to trace the issue.
Can anyone please point me in the right direction?
Unless you have reason to believe these errors are a problem, I wouldn't bother investigating them on their own.
You can look at the logs in your project to get error details.

Does anyone know how to use AWS App2Container(A2C)?

AWS App2Container (A2C) is a recently launched feature by AWS. It is a CLI tool to help you lift and shift applications that run in your on-premises data centres or on virtual machines so that they run in containers that are managed by Amazon ECS or Amazon EKS. Since there is not much info on the internet about this, apart from the AWS document so does anybody knows how to implement it and what are the dependencies required for it?
This is a fairly new service so most people will be relying on reading at the moment.
For JAVA applications the setup instructions on Linux indicate that you just download the app2container package and then run the following over your code
sudo app2container containerize --application-id java-app-id
For .NET applications the setup instructions on Windows indicate that it is exactly the same process, run the install file and that will have all dependencies.
The best way to try and implement this will be by following these tutorials step by step. Also remember at this time it is JAVA or .NET only.

HANA Express in Google Cloud Platform

Is HANA Express still available in GCP ? Earlier I used it and can still see $165 and 155 days left in free trial. But then when I am trying to search HANA from "Deploy Prebuilt application" I am not getting any hit .

I am also noticing this behavior recently, when I contacted the SAP, they said there is an issue going on currently with the HXE installation available, it will be fixed soon.

AKS traffic issues after Istio install

Has anyone else been experiencing severe networking issues after installing Istio onto a cluster? We are seeing helm deploys (of other services) hang and fail as well as the kube dashboard runs extremely slow. Kubectl commands still are quick (sub 200ms via -v=6).
This is after a vanilla Istio 0.8 install onto a fresh AKS (w/ RBAC enabled), have attempted various regions (East/West/Central US) and they all exhibit the same issue.
It's currently unusable for us, but maybe I'm just missing something, I haven't found any tickets about the same issue? I believe this began happening about a week ago (6/27) which is around the time Microsoft made some changes to their AKS clusters, but we started using RBAC at the same time so it could be any combination of the two.
Experiencing the same issue with istio v1.0, I think it's because of the continuously crashing galley instance in v1.0, but I did not experience such slowness with istio v0.8. Did you come up with a solution? For me it started to slow down when I deployed all my the applications.
The galley issue in v1.0 is solved by the way, it will be merged into the 1.0 release hopefully very soon. (https://github.com/istio/istio/pull/7605)

C++ in the cloud. Casablanca REST Service on Microsoft Azure

Hello fellow Azure users. I have created quite an extensive C++ REST service using the CasaBlanca REST SDK. When I began working on this project I as lead to believe that I could run it in the Cloud (Azure) . Please explain how best I can get this service to run on Microsoft Azure. I can't afford to re-program the entire project in another language like C# or Java. Thanks in advance!
If you're wondering why I believed CasaBlanca was meant for the Cloud:

Looking at the TechEd video I can see that they are using the SpeechService demo which you can find the source of here: https://hg.codeplex.com/microsoftcasablanca so you can understand how they performed the deployment to Azure.
Looking at the code I can see the solution is designed to be deployed to a Cloud Service Worker Role and includes a "Cloud Service" project in the Visual Studio solution - this is the project type which gives the "Deploy To Cloud" option which you see in the video.
Given that the demo is from 2012 there will have been many Azure SDK releases since then so the demo code may require an update, but the deployment method from Visual Studio 2012 and 2013 remains essentially unchanged.
Regardless how you're using casablanca, c++ applications can be run on Virtual Machines, web/worker role (stateless) VMs in cloud services, probably websites... Choosing between these is a matter of opinion (or at least dependent on the app you're building), and there's no single right answer.
