Statmgr monitors error messages which are produced by other Earthworm modules, and determines whether to report and how to report an error. The pageit box transmits these messages via modem to a pager service. Statmgr has a restart feature which allows the system to recover if any module hangs by only restarting the hung module.
Any module can request to be restarted if it's heartbeat stops.
Otherwise, no restart attempt will be made. Startstop will then kill the module process and restart the module. For each module monitored by statmgr, a descriptor file must exist and be specified in the statmgr configuratin file. The earthworm convention has been to use the suffix '.desc' to indicate a descriptor file. Who should receive email and pager messages.
