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 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
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
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.

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
Information Flow and Detail
Business view – the status of the business service
Operational view – status of application, system
and network components
Alarm detail – drill down for
more information to resolve
problems quickly
