| Monitor system performance locally and remotely |
| In another of our Windows 2000 Professional tips, you learned about the Performance console and |
| how it helps you monitor performance of your local system, such as tracking CPU, memory, or disk |
| usage. You can also monitor other computers across the network. For example, you might set up |
| the console to monitor ICMP traffic received by a group of computers on the LAN. The Performance |
| console by default displays the captured information as a graph, with each counter displayed in a |
| You can easily change the way the Performance console displays the information. For example, in |
| some situations, a histogram might be a better choice than a line graph. Or perhaps you want to |
| view the raw numbers. Maybe you want to change the color of a particular counter, add grid lines, |
| change background color, or modify other properties. To do that, right-click the chart and choose |
| Properties or click the Properties button on the toolbar. The resulting property sheet lets you |
| change most aspects of the way the data is shown. |
| You should also take a tour through the Performance Logs And Alerts branch of the Performance |
| console. The Counter Logs branch lets you create logs that record data about hardware and system |
| service usage. Trace logs let you log specific types of events when they occur. Both types of logs |
| support manual or scheduled start and stop. |
| The Alerts branch lets you direct Windows 2000 to generate an alert when a specific counter moves |
| over or under a value you specify. Using the previous ICMP monitoring example, you might create |
| an alert that would trigger when the computer received more than a certain number of ICMP |
| messages per second. You can have the alert send a network message, log the event, or run a |
| program, giving you lots of flexibility in defining how Windows 2000 handles the event |
