  1. Matakuliah : H0372/Manajemen Jaringan Tahun : 2005 Versi : 1/0 Pertemuan 08Remote Monitoring

  2. Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : • Menguraikan peran Remote Monitoring

  3. Outline Materi • Ketentuan RMON • Protokol • Mekanisme • Informasi yang dikumpulkan

  4. Network with RMONs Remote LAN Probe Router with RMON Switch Router Backbone Network Local LAN Router NMS Ethernet Probe Remote LAN Ethernet Probe

  5. RMON • Remote Network Monitoring, RFC 1757 • Design goals • offline operation • proactive monitoring • problem detection and reporting • value-added data • multiple managers

  6. Data SNMP BACKBONE SNMP RMON Analyzer Traffic NETWORK Traffic Probe Router Router LAN RMON Components • RMON Probe • Data gatherer - a physical device • Data analyzer • Processor that analyzes data • RMON Remote Network Monitoring • Standards-based network management protocol • Allows network information to be gathered at a single workstation • Defines additional MIBs to provide a richer set of data about network usage

  7. RMON Benefits • Monitors and analyzes locally and relays data; less load on the network • Needs no direct visibility by NMS; more reliable information • Permits monitoring on a more frequent basis and hence faster fault diagnosis • Increases productivity for administrators

  9. RMON MIB • RMON1: Ethernet RMON groups • rmon 1 - rmon 9 • RMON1: Extension: Token ring extension • rmon 10 • RMON2: Higher layers (3-7) groups • rmon 11 - rmon 20

  10. Token Ring Statistics Token Ring Token Ring History Statistics History Control Ethernet Statistics Ethernet Ethernet History Statistics History Control Host and Conversation Statistics Remotely Data Network Host HostTopN Matrix Monitored Gathering Manager Statistics Statistics Statistics Network Filter Group Packet Channel Packet Filtering Filtering Capture Alarm Event Generation Generation RMON Groups and Functions

  11. RMON Groups and Functions • Probe gathers data • Functions • Statistics on Ethernet, token ring, and hosts / conversations • Filter group filters data prior to capture of data • Generation of alarms and events

  12. RMON2 • Applicable to Layers 3 and above • Functions similar to RMON1 • Enhancement to RMON1 • Defined conformance and compliance
