The Watcher monitors all of the services registered with it. For Calendar Server, the registered processes are: cshttpd, csadmind , csdwpd, csnotifyd, and csstored.
The daemon csstored must be enabled. Be sure to set the configuration parameter local.store.enable to "y" . The enabling of csstored was optional in the previous version of Calendar Server, but now it is required. The csstored daemon must be successfully started before each service that accesses the store can be started. If it stops, then the dependent processes must be stopped and restarted also.
