Monitor network traffic

Each QBS member has an Azure Log Analytics workspace to capture logs. If you want to track incoming IP addresses connecting to your QBS member's transaction node, view the BlockchainProxyLog_CL logs.

This can be helpful when the IP addresses of your application stack have changed and you need to identify the IP addresses to add to your firewall rules.

Access the QBS Log Analytics

To access the QBS logs for your QBS member:

  1. Open your QBS member in the Azure Portal.

  2. Select your managed resource group in the Overview tab.
