National Chi Nan University Outline Introduction Automatic Event-Driven (AED) System – Simple Network Management Protocol – Syslog System Architecture – AWK – Pre-defined Events – Action and Pattern – Instant Messaging AED System Operation Conclusions and Future Work 2 2012/2/21Ya-Ling, Wang

National Chi Nan University Introduction Make Sure Your Facilities Work Normally – Replace some unstable component in advance – Administrators have to closely monitor their hosts A large number and heterogeneous device – Managers will configure them by different ways All these actions require the manager to have Internet access. 3 2012/2/21Ya-Ling, Wang

5
National Chi Nan University Simple Network Management Protocol (SNMP) SNMP is a widely used network management protocol. 5 2012/2/21Ya-Ling, Wang
6
National Chi Nan University Syslog-ng Syslog is a standard for logging program message. 6 2012/2/21Ya-Ling, Wang

National Chi Nan University AWK The AWK is a data processing language. With the data-driven scripting language, it will take pre-defined actions through different option. Uses the same idea of “patterns-and-actions”. – The managers can pre-defined a variety of events for AED to handle automatically via different options. 7 2012/2/21Ya-Ling, Wang awk -F':' '{ print $2 }'

National Chi Nan University Instant Messaging It would be beneficial to notify the administrator with instant messaging services The sendMsg is a PHP class which allows users sending messages to a contact from a specified account. Send messages 8 2012/2/21Ya-Ling, Wang

National Chi Nan University Pre-defined Events 1.When a user plugs out his/her device from the switch port within ten minutes, the AED should notify the manager. 2.If a device was plugged into a switch port, the bandwidth of the port will be restricted to 128kbps only. 9 2012/2/21Ya-Ling, Wang National Chi Nan University

National Chi Nan University Get rid of special case Got only import messages. Provides a White List for administrators to define special cases to exclude. – Upgrades temporarily – Hardware failure Filter abnormal message 11 White List : IP address, port

National Chi Nan University Conclusions and Future Work The pre-defined accidents can be solving in an effective and immediate way. Through the pre-defined scenarios, managers can be relieved from regular routine tasks. Future Work – Provide more pre-define events – Include web management interface – By creating an intelligent system to learn the script from the managers. 13 2012/2/21Ya-Ling, Wang
