Plugin and CMS phone-home calls send telemetry, license or update data to their vendor servers. Not classic crawlers — but can show up in logs if proxied through your server.

BotScope aggregates every Serf request in your session: which URLs it prefers, how many 4xx/5xx responses it gets, whether it crawls from one or many IPs, and what time window it's particularly active in.
