Azure eventhub input

Users can make use of the azure-eventhub input in order to read messages from an azure eventhub. The azure-eventhub input implementation is based on the the event processor host (EPH is intended to be run across multiple processes and machines while load balancing message consumers more on this here https://github.com/Azure/azure-event-hubs-go#event-processor-host, https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-event-processor-host). State such as leases on partitions and checkpoints in the event stream are shared between receivers using an Azure Storage container. For this reason, as a prerequisite to using this input, users will have to create or use an existing storage account.

Example configuration:

filebeat.inputs:
- type: azure-eventhub
  eventhub: "insights-operational-logs"
  consumer_group: "test"
  connection_string: "Endpoint=sb://....."
  storage_account: "azureeph"
  storage_account_key: "....."
  storage_account_container: ""

Configuration options

The azure-eventhub input supports the following configuration:

eventhub

The name of the eventhub users would like to read from.

consumer_group

Optional, we recommend using a dedicated consumer group for the azure input. Reusing consumer groups among non-related consumers can cause unexpected behavior and possibly lost events.

connection_string

The connection string required to communicate with Event Hubs, steps here https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-get-connection-string.

A Blob Storage account is required in order to store/retrieve/update the offset or state of the eventhub messages. This means that after stopping filebeat it can start back up at the spot that it stopped processing messages.

storage_account

The name of the storage account.

storage_account_key

The storage account key, this key will be used to authorize access to data in your storage account.

storage_account_container

Optional, the name of the storage account container you would like to store the offset information in.
