5.6 Generating Alarms (Syslog-ng)
This feature helps the administrator to manage the servers. It filters the
messages received by the serial port (the server’s console) based on the
contents of the messages. It then performs an action, such as sending an
email or pager message. To configure this feature, you need to configure
filters and actions in the
syslog-ng.conf file. (You can read more about syslog-ng in the Syslog-ng
section.)
How to configure
Alarm generation is strictly related to the syslog-ng configuration. It is
highly recommended to read the
Syslog-ng section before configuring this
feature. This section will show practical examples of utilization of this
feature.
The
/etc/portslave.conf related parameters are:
• conf.DB_facility - This value (0-7) is the Local facility sent to
the syslog-ng with data when syslog_buffering and/or alarm is
active.
• all.alarm - When nonzero, all data received from the port is cap-
tured and sent to syslog-ng with INFO level and
LOCAL[0+conf.DB_facility] facility. This parameter must be
set to a non zero value to activate alarm generation.
The syslog-ng reads from sources (files, TCP/UDP connections, syslogd
clients), filters the messages and takes an action (writes in files, sends
snmptrap, pager, email or syslogs).
Basically, alarms are triggered by a combination of sources, filters and
destinations. To connect the sources, filters and actions (any message
coming from one of the listed sources, matching the filters (each of them)
is sent to the listed destinations). Use this statement:
log { source(S1); source(S2); ...
filter(F1);filter(F2);...
destination(D1); Destination(D2);...
};
For more information about sources, destinations and filters, please refer
to the
Syslog-ng section. This
