I am looking for a code sample that shows how reliable stateless services on Service Fabric can communicate with each other using Azure message bus and MassTransit middle-ware. Preferably asp.net core service.

I'm migrating a Cloud Service application to a Service Fabric application.
I'm looking for a ServiceEnvironment equivalent to RoleEnvironment in order to get the service name from the environment variables.

IBM internally monitor services which is offered on cloud but somehow I need to get status of middleware services such as kafka,API Connect etc. It will help me to automate things if some service stopped/not accessable.
To monitor your provisioned instances of these services you could exercise them. For example on API Connect create an API called /health and curl the API to verify it is working. For kafka create a topic to check the health.
Currently in our project, we have few Stateless and Stateful services and then we have an API (which is again a Stateless service). Our API service is exposed over http and run of frontEnd Nodes in cluster. Any client from outside hits the WebAPi stateless service, which inturn can call other services via SF remoting. But other services are not exposed over HTTP. and individual services also can call each other via SF remoting.
As a part of a new requirement, there are some other services hosted in other cloud (Openshift) needs to access our Stateless and Stateful services directly (i.e. without the WebAPI service) over REST. I understand that we can expose our Stateless and Stateful services over http, by writing our own custom HttpCommunicationListener (which should implement "ICommunicationListener"). But apart from this I guess, we would need to configure some reverse proxy and Load Balancer stuff etc, to ensure that one URL works for all the requests.
Is this something, which can be achieved. If yes, can somebody points me to any documentation or code sample ?
I recommend having a look at Traefik as a reverse proxy and load balancer.
You can run it as a (containerized) ingress routing service inside the cluster, and direct HTTP calls to your services.
Here's the documentation.
Here's how to get started.
Here's an example.
Azure Service Fabric whats the purpose of different Services ,please give with examples and also step by step process for deployment
I think you need to take a look at the service fabric documentation.
Supported services
- Reliable Services, Reliable Actors, Guest Executable
Deployment - PowerShell, Visual Studio
I found this from several months back on Application Insights and Service Fabric and I'm wondering if there is any new information.
I would really like to get CPU, Memory, Storage and other metrics out of service fabric and the reliable actors. Having it presented in a user friendly HUD like app insights provides would be awesome!
Thanks!
On the azure portal, you can now create a resource called 'Service Fabric Analytics' to create a nice dashboard for your cluster. Configure as cluster like described here. It's OMS based, not Appinsights though.
The Service Fabric Solution helps identify and troubleshoot issues
across your Service Fabric cluster, by providing visibility into how
your Service Fabric virtual machines are performing and how your
applications and micro-services are running. Available features
include: • Get insight into your Service Fabric framework • Get
insight into the performance of your Service Fabric applications and
micro-services • View events from your applications and micro-services
Data collected: Service Fabric Reliable Service Events, Service Fabric
Actor Events, Service Fabric Operational Events, Event tracing for
Windows events and Windows event logs. Requirements: This solution
will only work if you have set up Azure Diagnostics on your Service
Fabric VMs, and have configured OMS to collect data for your WAD
tables.
In service fabric with Eventflow https://github.com/Azure/diagnostics-eventflow you had a option to send the diagnostics data to multiple data stores like WAD Tables, OMS, elastic search and application insights.
Have a look at it. It is really straight forward and easily integrate with ETW events and will serve your purpose.
