statd - network status monitor daemon
statd is an intermediate version of the status monitor. It implements a
simple protocol that allows applications to monitor the status of other
machines. lockd(1M) uses statd to detect both client and server
statd is started during system initialization if the chkconfig(1M) lockd
flag is set on.
Applications use RPC to register machines they want monitored by statd.
The status monitor maintains a database of machines to track and the
corresponding applications to notify of crashes. It also maintains a
database of machines to notify upon recovery of its own host machine and
a counter of the number of times it has "recovered."
/var/statmon/sm machines to monitor
/var/statmon/sm.bak machines to notify upon recovery
/var/statmon/state recovery counter (a.k.a. version number)
lockd(1M), network(1M), statmon(4).
The crash of a site is detected only upon its recovery.
