Adding Syslog Rules
Syslog is a client/server protocol that sends event notification
messages to the syslog receiver. These event notification messages
(usually called as syslog messages) help in identifying the authorized
and unauthorized activities like installing software, accessing files,
illegal logins etc. that take place in the network. In OpManager
Syslog rules helps in notifying you if some particular syslog messages
such as kernel messages, system daemons, user level messages etc. are
sent by the devices.
