Verify the deployment

1. Log in to the GCP console and navigate to Firestore.
2. Navigate to the FortiGateMasterElection table.
3. Make note of the primary FortiGate-VM IP address and ensure the voteState is done. See below for an example:

   

4. Navigate to the FortiGateAutoscale table and confirm that instances have been added to the cluster. Following is an example of a healthy cluster:

   

   The masterIp field displays the IP address of the primary FortiGate-VM. When an instance is removed from a cluster its record will not be deleted.

Verify the instance group

1. Log in to the primary FortiGate-VM instance using the public IP address from step 3 of Verify the deployment. The default admin port is 8443 and the default username/password is admin/<instance-id>.
2. Cluster information is displayed on the main dashboard:

   

3. VPN status is under Monitor > Ipsec Monitor, which shows the current connections between the FortiGates in the cluster.

   

4. Additional settings can be found in the Firestore collection under SETTINGS. See below for an example:

   

Cluster monitoring

Various cluster metrics are displayed in the GCP console under Compute > Instance Groups > YOUR-FORTIGATE-AUTOSCALE_CLUSTER > Monitor.

From here you can see the scale in and scale out actions that have been performed, as well as cluster health data.
