IMC also includes root symptom analysis and built-in downstream event suppression by mapping out the
network infrastructure and defining relationships between devices. It defines these relationships
automatically through its comprehensive discovery algorithms.
Using this information, IMC intelligently distinguishes between alarms that are most likely pointing to the
root cause and those that are merely a symptom of a problem elsewhere in the infrastructure. Operators
can specify alarm presentation based on these distinctions.
IMC also provides operators with the ability to modify IMC mapping of the core and access devices used
for root cause or symptom analysis and event suppression.
As with most other features, IMC provides operators with a single pane for viewing alarms in IMC as well
as several alarm viewing options. From each of the alarm views, operators can drill down to view the
detailed information for a particular alarm and take actions to correct the problem.
Operators can also drill down to the Device Details page for accessing the monitoring information and
configuration features for the device reporting issues.
IMC also offers the ability to notify members of the support organization. It supports email and SMS or
text notifications. In addition, operators can forward alarms generated in IMC to other IMC instances or
to other management systems including Help Desk system and manager of managers systems.
Performance monitoring and management
True to the FCAPS model, IMC also provides the ability to monitor the performance of devices managed
by IMC.
The Performance Management features provide the ability to customize the collection, alarming, and
presentation of performance data. When conditions are met for system-defined, user-defined, global, or
individual monitoring thresholds, performance monitors can be leveraged to:
• Collect performance information.
• Generate historical reports.
• Generate alarms.
IMC enables the real time and historical performance management for managed devices. It provides
over two hundred global system defined monitors for measuring the availability, accessibility, and
performance of network devices, such as routers and switches.
It also supports the performance monitoring of technologies including:
• IPSec VPNs
• WLAN
• QoS
• VSM
• RMON
Compile MIBs into IMC to create custom global monitors, which can then be applied to the monitor sets
for one or more devices.
Sixteen of the over two hundred system defined monitors are configured with polling intervals, threshold
settings, and alarm level settings. This enables immediate, proactive performance monitoring of devices
managed in IMC. Four primary performance monitors will automatically be added to new devices. By
default, the following indexes are monitored on devices:
• Availability
