Network Monitoring Workspace Overview

To analyze and aggregate device-level performance data, and to detect device faults, the Network Monitoring workspace uses a collection of data from managed elements. Performance data is collected automatically if the SNMP settings are set properly for a discovered device. The following performance data is collected:

• Collection

  • View historical performance data by using a graphical monitoring tool that allows customization of the parameters to be displayed and the devices to be monitored.

  • Create graphs and charts.

  • Create and export reports in PDF and HTML formats.

  • Define advanced variables that require calculations for historical performance monitoring.

  • Allow raw data to be rolled up into processed data, allowing data to be processed from a more-specific to a less-specific level (for example, data collected at a quarter hourly interval can be rolled into hourly data, hourly data can be rolled into daily data, daily can be rolled into weekly data, and weekly data can be rolled into yearly data).

• Thresholds

  • Set thresholds for performance data values—including specifying warning and error levels.

  • Create threshold graphs.

  • Generate threshold-crossing alarms that can be displayed or forwarded.

• Faults

  • Receive SNMP traps directly from devices and other enterprise management systems (EMSs).

  • Forward traps to other EMSs.

  • Generate and display events and alarms.

  • Get basic correlation with alarms; for example, clearing alarms and deduplicating alarms.

  • Detect device faults based on data collected from devices.

You can perform the following tasks from the Network Monitoring workspace:

• Node List: List all the devices under monitoring (see Viewing the Node List).

• Search: Search for devices (see Searching for Nodes or Nodes with Asset Information).

• Outages: View unavailable (down) services (see Viewing and Tracking Outages).

• Events: View events (see Viewing and Managing Events).

• Alarms: View alarms (see Viewing and Managing Alarms).

• Notifications: Display notices received by users (see Viewing, Configuring, and Searching for Notifications).

• Assets: Search asset information and assets inventory (see Working with Node Assets).

• Reports: View reports (see Viewing Reports).

• Charts: View charts (see Viewing Charts).

• Topology: View nodes in the network topology and the events and alarms associated with the nodes (see Working with Topology).

• Admin: Perform system administration (see Configuring Network Monitoring System Settings).

The main Network Monitoring landing page is a dashboard, displaying the most important information about your nodes:

• Nodes with outages

• Availability over the last 24 hours

• Notifications (outstanding notices)

• On-call schedule

• Key SNMP customized (KSC) performance reports (if defined and available)

In addition, from this page you can do quick searches on nodes and resource graphs.
