I want to monitor a running instance of an Azure Durable Orchestrator Function for changes (like when it completes, fails etc)
I know that I can poll the status API for changes, but i was wondering if there were any push-based functionality. I've looked into the source code but I can't seem to find any clues to extension points, interfaces etc that enables this.
Any ideas on how to achieve this?
Thanks!
Right now, publishing orchestration lifecycle events (such as created, completed, and failed) is limited to a custom Azure Event Grid Topic. This feature is currently in preview. Refer Durable Functions publishing to Azure Event Grid (preview).
Add a notifications section to the durableTask property of the file, replacing <topic_name> with the name you chose. If the durableTask or extensions properties don't exist, create them like this example:
{
"version": "2.0",
"extensions": {
"durableTask": {
"notifications": {
"eventGrid": {
"topicEndpoint": "https://<topic_name>.westus2-1.eventgrid.azure.net/api/events",
"keySettingName": "EventGridKey"
}
}
}
}
}
The following list explains the lifecycle events schema:
id: Unique identifier for the Event Grid event.subject: Path to the event subject. durable/orchestrator/{orchestrationRuntimeStatus}. {orchestrationRuntimeStatus} will be Running, Completed, Failed, and Terminated.data: Durable Functions Specific Parameters.
hubName: TaskHub name.functionName: Orchestrator function name.instanceId: Durable Functions instanceId.reason: Additional data associated with the tracking event. For more information, see Diagnostics in Durable Functions (Azure Functions)runtimeStatus: Orchestration Runtime Status. Running, Completed, Failed, Canceled.eventType: "orchestratorEvent"eventTime: Event time (UTC).dataVersion: Version of the lifecycle event schema.metadataVersion: Version of the metadata.topic: Event grid topic resource.
