Enable Azure Application Insights on the VM-Series Firewall
Publish firewall performance metrics to Application Insights.
The VM-Series firewall on Azure can publish
custom PAN-OS metrics natively to Azure Application Insights that
you can use to monitor the firewalls directly from the Azure portal.
These metrics allow you to assess performance and usage patterns that
you can use to set alarms and take action to automate events such
as launching or terminating instances of the VM-Series firewalls.
PAN-OS Metrics Published for Monitoring for a description
on the metrics that are available.
