Monitoring and High Availability

To monitor the firewalls in this deployment, you can use Nagios, an open-source server, network, and log monitoring software. Configure Nagios to periodically verify the response from the portal and the gateways' pre-login page and send an alert if the response does not match the expectations. You can also configure GlobalProtect Simple Network Management Protocol (SNMP) Management Information Base (MIB) objects to monitor gateway usage.
In this deployment there is only one instance of the GlobalProtect portal. If the portal becomes unavailable, new users (who have never connected to the portal before) will not be able to connect to GlobalProtect. However, existing users can use the cached portal client configuration to connect to one of the gateways.
Multiple virtual machine (VM) firewalls in AWS configured as GlobalProtect gateways provide gateway redundancy. Therefore, configuring gateways as a high availability (HA) pair is not required.
