This topic describes how to configure two FortiAnalyzer units as the Analyzer and Collector and make them work together. In the scenario shown in the diagram below, Company A has a remote branch network with a FortiGate unit and a FortiAnalyzer 400E in Collector mode. In its head office, Company A has another FortiGate unit and a FortiAnalyzer 3000D in Analyzer mode. The Collector forwards the logs of the FortiGate unit in the remote branch to the Analyzer in the head office for data analysis and reports generation. The Collector is also used for log archival.
