Azure Firewall: New Monitoring and Logging Updates
Contributors: Eliran Azulai and Yuval Pery
Monitoring, management, and innovation are core pillars of Azure Firewall. With this in mind, we are delighted to share the following new capabilities:
- Resource Health is now in public preview
- Embedded Firewall Workbooks is now in public preview
- Latency Probe Metric is now in general availability
When you monitor the firewall, it’s the end-to-end experience that we continuously strive to improve. Our aim is to empower you to make informed decisions quickly and maximize your organization's security demands. Understanding the importance of having visibility into your network, this release focuses on making it easier for you to monitor, manage, and troubleshoot your firewalls more efficiently.
Azure Firewall is a cloud-native firewall as a service offering that enables customers to centrally govern and log all their traffic flows using a DevOps approach. The service supports both application and network-level filtering rules and is integrated with the Microsoft Threat Intelligence feed to filter known malicious IP addresses and domains. Azure Firewall is highly available with built-in auto-scaling.
Resource Health is now in public preview
With the Azure Firewall Resource Health check, you can now view the health status of your Azure Firewall and address service problems that may affect your Azure Firewall resource. Resource Health allows IT teams to receive proactive notifications regarding potential health degradations and recommended mitigation actions for each health event type. For instance, you can determine if the firewall is running as expected with an "Available" status or if there was downtime due to platform events with an "Unavailable" status.
This preview is automatically enabled on all firewalls and no action is required to enable this functionality. For more information, see Azure Resource Health overview - Azure Service Health | Microsoft Learn

Embedded Firewall Workbooks are now in public preview
The Azure Firewall Workbook presents a dynamic platform for analyzing Azure Firewall data. Within the Azure portal, you can utilize it to generate visually engaging reports. By accessing multiple Azure Firewalls deployed throughout your Azure infrastructure, you can integrate them to create cohesive and interactive experiences.
With the Azure Firewall Workbook, you can extract valuable insights from Azure Firewall events, delve into your application and network rules, and examine statistics regarding firewall activities across URLs, ports, and addresses. It enables you to filter your firewalls and resource groups, and effortlessly narrow down data sets based on specific categories when investigating issues in your logs. The filtered results are presented in a user-friendly format, making it easier to comprehend and analyze.
Now, Azure Firewall predefined workbooks are two clicks away and fully available from the Monitor section in the Azure Firewall Portal UI:

Latency Probe metric is now generally available
The Latency Probe metric is designed to measure the overall latency of Azure Firewall and provide insight into the health of the service. IT administrators can use the metric for monitoring and alerting if there is observable latency and diagnosing if the Azure Firewall is the cause of latency in a network. This troubleshooting metric is helpful for proactively engaging in potential issues to traffic or services in your infrastructure.
Azure Firewall latency can be caused by various reasons, such as high CPU utilization, throughput, or networking issues. As an important note, this tool is powered by Ping Mesh technology, which means that it measures the average latency of the ping packets to the firewall itself. The metric does not measure end-to-end latency or the latency of individual packets.
