in our demo. To add a performance monitor, we click the Add Counter button in the toolbar. The list of available counters displays all available counters in the operating system. Today we are going to focus on Certificate Services. By expanding the CA you will see a list of available options. These options will give us a better understanding of those configuration options that are best for a particular environment. We will add request processing time as our CA counter. As shown in Figure 24.
