I have four appliances FortiWeb (6.3.19) working in Standard Active-Active HA and I want to configure Machine Learning as additional security mechanism. Admin guide has one weird limitation "Machine learning is not fully supported when FortiWeb is deployed in active-active HA mode. It doesn't work on the secondary node; On the primary node, it works but not always stable, for example, after system reboot or HA role switch, the machine learning may stop working.". I understand correctly that ML will work only on Master role appliance and traffic that routes via secondary appliances will not analyze? https://docs.fortinet.com/document/fortiweb/6.3.19/administration-guide/193258/machine-learning
I didn't find any information about this limitation for v.6.4.2 release. Do you known may be it was fixed there?
Machine learning data—Machine learning database is synchronized from the primary node to the secondary node in Active-Passive mode. The data is synchronized every 10 minutes. In Active-Active mode, only machine learning Anomaly Detection database is synchronized. Bot Detection and API Protection database is not synchronized
