  1. Design and Initial Development of Prototype Demonstration of an SNMP Manager & Agent for Monitoring Web Server 17 December 2009 Group 1 Developers: Peter Hannon Brian Walshe Researchers: Arnav Aggarwal Paul Gildea PM: Paul Soprovici

  2. Objective • Design an SNMP Manager & Agent for Monitoring Web Server

  3. SNMP Model • Manager • Set • Get • Get Bulk • Agent • Trap • Management Information Base An SNMP-Managed Network Consists of Managed Devices, Agents, and NMSs (http://www.cisco.com/en/US/docs/internetworking/technology/handbook/SNMP.html#wp1022871)

  4. Design • SNMP – used by the manager to communicate with the agent • Manager – SNMP4J Libraries • Agent - AdventNet SNMP Agent Toolkit for Java • Agent to Web Server communication through JMX (Java Management Extensions) calls

  5. Design -2 • What to monitor? • Set: • restart the server • Enable/disable http port • Set connections per second threshold • Get: • Hostname/port • Uptime • Connections per second/ threshold • Heap memory usage • Get bulk • Servlet table • Trap: • Connections per second threshold exceeded notification

  6. Implementation - Manager SET GET GET BULK TRAP

  7. Implementation - Agent • MIB: designed in AdventNet • Agent: generated in AdventNet 1.3.6.1.4.1.1.5.3

  8. Evaluation • Comparison of the values returned by Gets and Get Bulk with JConsole • Sets have the expected results • Threshold and Traps • Use Python to generate multiple requests from urllib import urlopen import time for i in range(1000): urlopen("http://localhost:8080") time.sleep(0.01) If connectionsPerSec > connectionsThreshold TRAP

  9. Conclusion:

  10. DEMO
