/var/log/manager: Daily Perspectives for the Sysadmin and the Manager

Consider a city zoo on a clear blue-skies summer day. Animals to tend and children’s field trip groups to marshal. Line up to pet the goats, then stop for a juice break. Underneath the zoo, a subway switching station. Full commuter trains barreling past at 80 miles per hour. Red lights, green lights, timing trains and tracks and stops and people and go-go-go in the pitch-dark tunnels and klieg-bright platforms. You can walk up the steps from the train platform and be at the zoo.
