The Event Manager (EVM) daemon, receives events from posting clients
and distributes them to subscribing clients that have indicated that
they are interested in receiving the events. The daemon is a critical
system facility that is started automatically when the system transi‐
tions to run level 2, and which should not be terminated. The daemon
in turn starts the event logger, and the channel manager,
On startup, the daemon reads its configuration file, the authorization
file, and the event template files stored under the directory. If
these files are modified while the daemon is running, the command must
be used or a signal must be sent to instruct the daemon to reconfigure
The system administrator can control access to events by modifying the
EVM authorization file,
As a daemon, does not have a standard output. Any error messages are
written to the file
The EVM daemon is monitored by the Essential Services Monitor daemon,
which automatically restarts if it terminates unexpectedly. See
