Product: PerformanceGuard — a separate CapaSystems product; do not apply this page to any other.
The following parameters control the behavior of the PerformanceGuard web interface. They can be set either in the config\_params database table or in the file performanceguard.xml (the default location of the file is \\[PerformanceGuard installation folder\\]\display\conf)
## **Service Settings**
This parameter controls the PerformanceGuard Web Server service.

When demo mode is activated, the internal clock in the PerformanceGuard web interface will be stopped and reset to the time stamp of the last delivered sample. When in demo mode PerformanceGuard won't accept incoming data from agents, and it won't delete old data (the cleanup job is stopped). |
## **Access Logging**
Access logging, that is logging of who accesses the PerformanceGuard system, is by default *not* enabled. When access logging has been enabled, you can view the access log in the folder \[PerformanceGuard installation folder\]\display\accesslogs.

| **Set in** | performanceguard.xml |
| **Type** | Number of days |
| **Default value** | 7 |
| **Description** | Determines how the log access log is kept for if access logging is enabled.
⚠️ The value *0* (zero) will keep the log forever. We don't recommend that you keep the log forever because it will take up more and more disk space. |
