Azure SQL

Pull logs from Azure Event Hub to Logstash & get started with Azure application logging.

Follow this step by step guide to get 'logs' from your system to

Step 1 - Prerequisites

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

Confirm you have the following:

  • An Azure SQL Database you wish to get diagnostic Logs from.
  • An Eventhub you wish to stream the SQL diagnostic logs to.
The Azure event hub Logstash plugin is only available for stacks running Logstash 6.4 onwards

Step 2 - Configure Diagnostic Logs

Once you have confirmed you have everything required it's time to configure diagnostic logging.

Choose your Azure SQL Database you wish to get diagnostic logs from. You will need to browse to the Diagnostic Settings from the left hand menu.

Choose your Azure SQL Database

Go ahead and choose add diagnostic setting, enter a suitable name and then select the diagnostic logs you need.

Select stream to an Eventhub and enter the details of your Eventhub.

Once you're happy with the settings select save.

Save settings

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.

example connection string

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
