9 Performance management
IMC provides real time and historical performance management for managed devices. The Performance
Management features provide you with the ability to customize the collection, alarming and presentation
of performance data. In addition, you can leverage system or user defined global or individual monitors
to collect performance information, generate historical reports on the performance of devices or
generate alarms when performance monitors meet threshold conditions.
Upon installation, you have access to several groups of more than two hundred globally defined
monitors that define the monitoring options for configuring monitoring for individual devices.
Within these global monitors, sixteen come configured with polling intervals, threshold settings, and
alarm settings configured to enable immediate, proactive performance monitoring of devices managed
in IMC.
Of the sixteen global monitors, four are immediately added to the performance monitoring of devices
whenever devices are added to IMC, providing a standard set of monitors for immediate performance
monitoring and reporting. These four monitors include Device Un-reachability Proportion, Device
Response Time, CPU Usage, and Memory Usage.
IMC also provides the ability to customize the list of global monitors that define performance monitoring.
You can add custom monitors to the set of global index settings monitors, modify or remove the threshold
settings for global monitors that already have these settings defined, add threshold settings for global
monitors that have no pre-defined thresholds set, or add, remove, or modify the set of default global
monitors that are applied when a device is added to IMC.
In addition to global monitoring options, you can also customize the list and configuration of monitors
that are applied to individual devices or groups of devices or add monitors to or remove monitors from
the list for one or more devices. Naturally, you can also add, modify, or remove the threshold settings for
performance monitors that determine when a performance monitor generates an alarm.
You can create views for viewing the historical data collected by the performance view. You can also
organize views by folders and create shortcuts for easy access to performance views from the left
navigation tree. Lastly, you can customize which performance views are available from the Network
Topology.
Managing performance with global index settings
IMC provides you with over two hundred globally defined monitors organized into eight monitor groups.
The first of these is a system monitoring group that includes monitoring for general system performance
such as reachability, CPU, memory, and device response time.
In addition, the Performance Management feature provides device specific performance monitoring for
IPsec VPNs, WLANs, IVS, QoS, VSM, and RMON. All of these monitors can be found under Global
Index Settings.
There are sixteen global monitors already configured with polling intervals, threshold settings and alarm
level settings, enabling you to immediately and proactively monitor the performance of devices
managed in IMC.
Out of the box, you have a standard set of monitors for performance monitoring and reporting along
with over 200 monitors that can be configured with threshold settings and applied to specific devices for
