Better Stack Azure Event Hub logging
Start logging in 5 minutes
Send logs to Better Stack from Azure Event Hub using Vector in Azure Container Instance.
1. Get Vector deployment
Copy and save the following configuration as vector-deploy.yaml:
Save configuration as vector-deploy.yaml

2. Fill in your Azure Event Hub values
Fetch the following values using Azure CLI and fill them in the vector-deploy.yaml file:
Get EVENTHUB_NAMESPACE
az eventhubs namespace list --resource-group <YOUR_RESOURCE_GROUP> --query "[].name" -o tsv
Get EVENTHUB_NAME
az eventhubs eventhub list --resource-group <YOUR_RESOURCE_GROUP> \
--namespace-name <YOUR_NAMESPACE> --query "[].name" -o tsv
Get EVENTHUB_CONNECTION_STRING
az eventhubs namespace authorization-rule keys list \
--resource-group <YOUR_RESOURCE_GROUP> \
--namespace-name <YOUR_NAMESPACE> \
--name RootManageSharedAccessKey \
--query primaryConnectionString -o tsv
3. Deploy Vector
Deploy Vector as Azure Container Instance using the following command:
Deploy Vector via Azure CLI
az container create \
--location eastus \
--resource-group <YOUR_RESOURCE_GROUP> \
--file vector-deploy.yaml
Fill in your values
Replace location and resource groups parameters in the command above.
You should see your logs in Better Stack → Live tail.
Troubleshooting
Check the deployment status using the following commands:
Check deployment status
az container show --resource-group <YOUR_RESOURCE_GROUP> --name vector-betterstack --query instanceView.state
az container logs --resource-group <YOUR_RESOURCE_GROUP> --name vector-betterstack
