Box 2: SubjectBeginsWith -
Box 3: Microsoft.Storage.BlobCreated

Scenario: Log Policy -

"destination": {
"endpointType": "webhook",
"properties": {
"endpointUrl": "https://example.azurewebsites.net/api/HttpTriggerCSharp1?code=VXbGWce53l48Mt8wuotr0GPmyJ/nDT4hgdFj9DpBiRt38qqnnm5OFg=="
}
},
"filter": {
"includedEventTypes": [ "Microsoft.Storage.BlobCreated", "Microsoft.Storage.BlobDeleted" ],
"subjectBeginsWith": "blobServices/default/containers/mycontainer/log",
[1]
"isSubjectCaseSensitive ": "true"
}
}
}

You mean to say that documentation link has eventType as "Webhook" as an example. But isn't that an example? Where is the reference to say it is a webhook? The question itself is not clear

Yeah, but this is sending an event for every log file that is created.

By googling the case study i found more text that fits more appropriately: Policies Log policy All Azure App Service Web Apps must write logs to Azure Blob storage. All log files should be saved to a container named logdrop. Logs must remain in the container for 15 days.

It looks correct purely based on options and there is no need to read the big scenario. But I wonder why it is reacting on logdrop container events. That's where the service itself is writing log files to. Won't it create an endless loop?

"All Azure App Service Web Apps must write logs to Azure Blob storage" -There are n (production) Web apps that write logs to a blob storage. -On that blob storage an event grid is put to trigger the event when blobs are written. -From that event a function is triggered, doing great thing with policies.

marvelous microsoftiness, probably this is for the subscription for the anomaly detection service and not the policy service where they expliclty mentioned event grid to confuse you. Once you pass this exam, the certification can be used when applying for a job at CSI new york. For finding clues where they do not exist.

What is a webhook and how do you use it? Webhooks are automated messages sent from apps when something happens. They have a message—or payload—and are sent to a unique URL—essentially the app's phone number or address. Webhooks are almost always faster than polling, and require less work on your end. They're much like SMS notifications.

The question is really worded poorly. The subscription is for events that are inserted into the container and a webhook is invoked when a log file is created in the storage container. I assume that the webhook point to a function (?) that analyze the log with a machine learning model and THEN if there is an anomaly call an azure function to notify adminstrator via mail. Am I missing something ?

It's in the text: "You develop and deploy a stateful ASP.NET Core 2.1 web application named Policy service to an Azure App Service Web App. The application reacts to events from Azure Event Grid and performs policy actions based on those events" The controller of "Policy service" is given in the code EventGridController.cs. So the subscription in Grid triggers a webhook to the Policy service and executes the 'Process' controller function there .

> an Azure Function that emails administrators is called by using an HTTP WebHook The question is about the EventGrid subscription, not how another Function is called. How do they fit together?
