Using the Web Task Manager
The Web Task Manager extends the functionality of the Microsoft Windows Task Manager to provide network device overview information about processes occurring on a device, device performance, and device interface activity. The Web Task Manager graphs and displays real-time information using SNMP or WMI device connections.
You can use the Web Task Manager to identify device issues and take corrective action on a device.
There are three tabs that provide device information:

: When viewing information for devices running Microsoft Windows, information gathered by SNMP may reflect a delay of one minute or more. This delay is caused by a limitation in how often Microsoft Windows updates SNMP values. For this reason, we recommend using a of or when using SNMP to view interface information about a device running Microsoft Windows.
