Utilization index is a value between 0 and 100 that describes the usage (load) of different dynamic values. Default enabled. Send reports every 900 Sec. (15 Min.).

| **Memory**      | Index (0-100) of physical memory used, *not* including reserved or cached memory.                                                                                                                                                                                                                                                                                          |
| **CPU**         | Index (0-100) of CPU cycles used of the total cycles available over all the cores. (0-100)                                                                                                                                                                                                                                                                                 |
| **Disk**        | Index (0-100) of the number of disk read/write operations compared to the maximum observed amount of operations. The previously observed maximum value is used as a baseline, and this number is reset when the PerformanceGuard agent is started. This means that it's perfectly normal that the computer is having a disk utilization index close to 100 while starting. |
| **Net**         | Index (0-100) of network bandwidth used compared to the maximum rating of the current Network Interface Card (for example1 GB if a LAN is used). The maximum bandwidth may change if network changes take place, for example switching between LAN and WiFi networks.                                                                                                      |
