Perhaps a rather simple question, yet I couldn't find the answers after doing some searching.
After I have send an event to an Azure event Hub (via the Java code), how could I check back in the Azure Portal about the event that I have sent ?
(so that I could inspect the header and body of the event content for verification).
In the Azure Portal, after I have clicked in the event hub, there is a metric to show the incoming requests, but this only shows the counts, but I would want to inspect the individual event recevied.
You can inspect the data on the portal with Azure Stream Analytics test consumer which can be loaded on the entity blade.
To my knowledge, it's not currently possible to inspect Event Hubs events via the portal. To do you, you'd either need to read the events using one of the SDKs or a product like Service Bus Explorer to inspect them.
I believe the answer to your question is Azure Monitor. Check out this link and see if it helps.

I am using the built in events tab under the IoT Hub to route data to an event topic. The subscriber is an Azure function (It has it's system identity enabled).
Data is routing to the event topic but the delivery is failing when trying to reach the Azure Function.
Diagnostic logs do not show anything useful:
Event Grid Subscription:
Is there a way to use this functionality even though the Azure Function has it's System Identity turned on?
I noticed this question had a similar problem and solved it using RBAC but I can't ask a question as I don't have enough reputation to comment. Event Grid Subscription event going to delivery failure
Any ideas?
I have provisioned Azure Event Grid domain in the portal and created a couple of Domain Topics under the hood. Also, a service bus queue has been configured as an endpoint to receive those events.
Now, I just want to send a few sample events to the Azure Event Grid Domain. How do I go about it? is there any tool available to send the events out of the box?
Any suggestion is much appreciated.
Basically, any REST Client tool can be used for posting an event to the AEG domain or you can try my Azure Event Grid Tester:
I have configured Azure Information Protection analytics through the Azure portal for my subscription and I am able to see log data under the Activity logs (preview) tab.
I want to forward that log data to a configured Event Hub but I have not found a way to do it. This data appears to be written to a table called InformationProtection_CL. How do I get that query output to stream to an Event Hub? Is what I'm trying to do possible?
You can use the REST API Query - Get to get the log data in the table.
GET https://api.loganalytics.io/v1/workspaces/{workspaceId}/query?query={query}
Then follow this doc to send events to the event hub programmatically, the specific situation and language depend on you.
https://learn.microsoft.com/en-us/azure/event-hubs/event-hubs-dotnet-standard-getstarted-send#send-events
Basically what I understood from few Azure topics is as below:
Azure Event Hub - where data is received initially and converted into events
Service Bus- acting as a queue
Azure Event Grid - where events converted in hub are transferred here.
so the connection is like below:
Hub -> Service Bus -> Event Grid -> Pub Sub -> Storage
I understood this concept. My problem is I want data to be pushed from the event grid to GCP (subscription / topics). My question are:
How can I establish this using PUSH method?
What do I need to develop exactly?
How can I push things from grid to pubsub/subscriptions?
I found this link where data is getting published into Event Grid but I want to push data from the event grid to gcp. Can anybody explain me where am I going wrong or what exactly should I start with. I am new to this and its very confusing so I just need little bit of guidance over here.
I have below doubts:
Is there any direct subscriber option available with event grid listener? I mean can I directly link my google storage account with this listener so, whenever there is an event triggered it will be directly pushed to my GCP account(I don't have Azure account with me right now since access issue is in progress so I can't see it that's why I am asking here)
Suppose I have 20 columns in my data but I want only 16 columns to be pushed in GCP so is there any customization possible while sending data from event grid/event hub to pub/sub
If I write custom connectors code as per the links provided in the below answers then how can I run it? I mean where I can deploy those scripts on the cloud so that they will be triggered automatically whenever an event is triggered?
Can I implement webhooks in this scenario? (as an alternative to connectors), If yes then how can I do it and on which side do I need to create it?
Also, I read some articles and I came to know from a few guys that they experienced data loss in this entire process. So, what's the possibility over here and how can it be avoided
Can anybody explain me where am I going wrong or what exactly should I start with.
It's right here:
so the connection is like below:
Hub -> Service Bus -> Event Grid -> Pub Sub -> Storage
Although this might be the case, it sounds very much as if you're looking at one (very) specific scenario where data flows in this exact way.
Azure Event Hub, Azure Service Bus and Azure Event Grid can work together, but can also be used completely separate from each other.
Event Grid
The purpose of Event Grid is to enable Reactive programming. Use this when you want to react to (status) changes.
Event Hubs
Event Hubs facilitate a big data pipeline. Use this when you need telemetry and distributed data streaming.
Service Bus
The purpose of Service bus is to enable High-value enterprise messaging. Use this when you want to do something like Order processing and financial transactions.
In some cases, you use the services side by side to fulfill distinct roles. For example, an ecommerce site can use Service Bus to process the order, Event Hubs to capture site telemetry, and Event Grid to respond to events like an item was shipped.
In other cases, you link them together to form an event and data pipeline. You use Event Grid to respond to events in the other services. For an example of using Event Grid with Event Hubs to migrate data to a data warehouse, see Stream big data into a data warehouse.
Taken from the very interesting and important documentation article Choose between Azure messaging services - Event Grid, Event Hubs, and Service Bus
EDIT
My problem is I want data to be pushed from event grid to GCP (subscription / topics). So how can I establish this using PUSH method??
Possibly the simplest solution is to have an Event Grid Event trigger a webhook (which might run an Azure Function or a Google Cloud Function) which in turn puts the event/message on the GCP Topic.
Publishing messages is quite well documented. There are examples on how to do so with a REST call, command-line, C#, Go, JAVA, NodeJS, PHP, Python and Ruby.
EDIT 2
What you need to do is create an Event Grid Subscription to listen to and handle Event Grid Events.
Here's an example screenshot on how to listen for events for a specific Storage Account and call a WebHook whenever such an event occurs:
Pay attention to the "Endpoint Details": that's where you can specify to, for instance, call a webhook every time an event is triggered.
The easiest way to transfer the EventHub generated events would probably be to create an EventHub event receiver in Node.js (which you mentioned in your comments) as described here, which receives events and publishes them to Cloud Pub/Sub directly, as described in the Cloud Pub/Sub publisher documentation for Node.js.
In my python application, if any bad/good event happens, I want to send the event details as notification message to user's email addresses or phone #s that have been subscribed to this application. So I am looking for publisher-subscriber model azure cloud
Looks like multiple Azure services achieving similar goal but having a thin line of differences. Event hubs and notification hubs seems promising. So my question is as follows:
Can email ID/phone # be subscribed to Azure event hub and receive the message being sent/produced to Azure event hub?
If not event hub, what is the correct option? Can I achieve it with Service bus or Notification hub?
In AWS, there is a service called SNS (Simple Notification Service) where one can subscribe email/phone number and opt for receiving event messages about that application. I am looking for equivalent to that in Azure.
You can use the Azure Logic Apps / Azure Functions with Event Hubs to achieve this easily.
Using logic apps you can do like simple as below image.
Logic Apps has many in-build connectors for most all Azure Services, you can use Event-hubs,Service bus,SQL etc.,
You can find all the list of available connectors here
Update 1
Once you connected the Event-Hubs to send an Email connector, you will automatically get all the available source data from event-hubs to email task. See below
You can achieve this by using Azure Application Insights. With this, you will be able to monitor your application and receive alerts during application unavailabillity, failures or even during performance issue.
