Hello @Yaseen Zafar ,
You can monitor Azure Firewall using firewall logs. You can also use activity logs to audit operations on Azure Firewall resources. Using metrics, you can view performance counters in the portal.
You can access some of these logs through the portal. Logs can be sent to Azure Monitor logs, Storage, and Event Hubs and analyzed in Azure Monitor logs or by different tools such as Excel and Power BI.
In order to Monitor Azure Firewall logs and metrics, do follow up the below link,
