Purpose of Monitoring

• 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
  enterprises current operation
• Examples are capacity, utilization, accuracy,
  etc.
• Manageability
• Modify operating parameters, traffic patterns,
  and device configurations based on current system
  health and status

Monitoring Objectives

• 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

Concords 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.

eHealth Functionality

• 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
