eHealth Network Monitoring Network Tool Presentation J. Gaston Senior Network Design Seminar Professor Morteza Anvari 10 December 2004

Network monitoring is a method of efficiently ensuring several goals are achieved – Availability Ensure customers can use the network and its supported systems for a specified percentage of time Reduce MTBF and MTTR by quickly identifying root cause of outages – Performance Ensure a variety technical metrics are achieved by providing real-time measurement of enterprise’s current operation Examples are capacity, utilization, accuracy, etc. – Manageability Modify operating parameters, traffic patterns, and device configurations based on current system health and status Purpose of Monitoring

Manage performance and availability of LANs, WANs, and network devices Measure current performance to establish a baseline and verify compliance with service level agreements (SLAs) Prevent outages and ensure availability by identifying which resources are at risk of failure Manage servers supporting network services, such as firewalls, DNS, and DHCP servers, on Windows and UNIX platforms Perform continuous, active tests of application availability and functionality Monitoring Objectives

Concord’s Approach ~ Business Service Management Business Service Management delivers… Visual representation of the dependencies between business processes, business applications and the IT infrastructure. Reduced downtime and shorter problem resolution time because IT support focuses on solving the correct, high priority, business-relevant issues. Operational efficiency because operators can use a single console for viewing the status of business services as well as for displaying IT infrastructure views. Business service views can be customized and enabled for viewing by business users, thus giving the line of business a better understanding of how the IT infrastructure is performing.
