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.

Variety of mechanisms monitor enterprise at multiple levels– SystemEdge agents installed on servers to track CPU load,

memory usage, and disk activity– RMON probes collect packet statistics and protocol data from links,

paths, and network devices– Capable of receiving third party MIBs to leverage existing

technology and monitoring solutions Information assembled by central console server and

correlated to build various views and reports– Oracle database provides backend storage and data management– Rules and thresholds highly customizable to ensure alerts and

reports are tailor to needs of user, whether technical or business
