Azure Activity Logs

Pull Activity logs from Azure to Logstash

In Microsoft Azure the Activity Log is a platform that provides insights into subscription level events, including auditable details of when a resource is modified or when a container is started. By configuring the required activity logs to forward to Event Hub we can then pull them into the ELK Stack via Logstash.

Step 1 - Ensure Azure Event Hub

Before you begin you will need to ensure you have an available Azure Event Hub in the Azure Portal.

You should create a diagnostic setting to send the Activity logs to this Event Hub.

View your Azure event hub

Once you have configured your Event Hub we now need to confirm messages are arriving.

Step 2 - Confirm Messages in Event Hub

In your Azure Portal browse to your Event Hub, from the dashboard you should be able to see messages arriving.

Ensure there is recent activity on the graph and the incoming requests isn't zero.

Step 3 - Configure permissions

Once you have data streaming to your Azure event hub, it is recommended to create a Consumer Group specifically for Logstash and not to reuse any default or existing groups.

The Logstash input supports multiple event hubs - the connection string for each hub can be found in the Azure Portal -> Event Hub -> Shared access policies.

A blob storage account is used to preserve state across logstash reboots. The Storage account connection string can be found in the Access Keys section under the Storage Account Settings menu in the Azure Portal

Step 4 - Configure Logstash for Azure Event Hub

To start pulling logs and metrics from the Azure Event Hub to your Stack you need to configure an Azure Logstash Input on your Stack.

Go to Dashboard will verify your input before it is applied, we will contact you to confirm when this has been completed.
