Bot analysis
Log&Report > Monitor > Bot Analysis displays statistics on access by automated clients such as search engine indexers, content scrapers, and other tools. Statistics are gathered by Real Browser Enforcement in anti-DoS rules, Bad Robot and Allow Known Search Engines. Based on this data, if an automated tool is abusing access, you can configure rate limiting such as with “Combination access control & rate limiting”.
