<h2>About</h2>
|
||
|
|
This example simulates a real-time display of CPU utilization in a web farm.
|
||
|
|
Data is updated in real-time, and cells with changed data are highlighted.
|
||
|
|
You can also click "Find current server" to scroll the row displaying data for the current
|
||
|
|
server into view and flash it.
|
||
|
|
