Event hub messages will be ingested into Elasticsearch using Logstash pipeline, thus first resource I am going to create is Event Hub. Please follow steps listed in this article to create an Event Hub. The main pointers are Event Hub name I have selected for this sample solution is ‘logstash’. If you select a different name, update event hub name in the source code. Keep a note of Event Hub connection string as this needs to be updated in Logstash pipeline and Event Hub messages publisher client. Source code uses ‘$Default’ Resource_Group. Update this value if you create a Resource_Group

The next resource which you will need to create is Azure Blob Storage. Please follow steps listed in this article to create a storage account. Once storage account is created, create Blob Service-> Blobs. The main pointers are Blob container name I have specified in source code is ‘logstash’. If you select a different name, update storage container name in the source code. Keep a note of Storage connection string as this needs to be updated in Logstash pipeline.
