Name

alertd — The SNMP trap sending daemon

Synopsis

alertd [-hv] [-d dbglev] -f cfgfile

Description

The alertd daemon is a component waiting for messages sent via special UNIX sockets (security.alert, security.notify, system.alert and system.notify) in the /var/run/alertd directory and send them as a SNMP trap to a set of SNMP managers.

The daemon runs in fact as three processes, like Kernun proxies do. The main process just controls run of its children. The Asynchronous Configuration Resolver provides for DNS resolution refreshing. The regular child process handles the real operation.

Signals

The alertd daemon handles following signals:

SIGUSR1

Log level increasing.

SIGUSR2

Log level decreasing.

SIGINFO

Operation status logging; parent process logs info about all children, child process logs current status of all ping groups.

SIGHUP, SIGINT, SIGQUIT, SIGTERM

Immediate termination; the daemon immediately closes the service.

Options

-h

Print usage information.

-v

Display version information and exit.

-d dbglev

Set debuging level to a specific number. Permitted values are 3 through to 9, 3 being the least and 9 the most verbose. See logging(7) for details. This setting is relevant only till configuration reading is finished.

-f cfgfile

Read cfgfile for configuration information.
