What are the MMC snap-ins provided by windows for monitoring security, performance, and error events?-tech10032012

The Event Viewer snap-in : Lists application, system, and security events as they occur on the system. Use this tool to see what is currently happening on the server and to get specific information about a particular event.
The Performance snap-in : Lets you create new events to display in the Event Viewer and allows you to track event counters over time for display graphically or in report form.
