:::caution
You can only do this if you're a PerformanceGuard administrator.

PerformanceGuard administrators are able to customize the PerformanceGuard web interface: Select **ADMINISTRATION > Setup > Parameters**, and then select the **Display** tab.

Customization options include (but are not limited to):

# **Front Page**

The page that shows up when you open the PerformanceGuard web interface is determined by the parameter **Start URL**.

# **Computer Activity Colors**

In [Computer Search](/performanceguard/analyze/computer-search/) results, the activity levels of computers are represented by these indicators:

 (active)
 (recently active)
 (inactive)

With the parameters **Client inactivity minutes yellow** and **Client inactivity minutes red** you can change the number of minutes for which computers must have been inactive before indicators change from green to yellow and from yellow to red.

# **Traceroute Latency Colors**

In [I Want to Know if There's Network Latency](/performanceguard/i-want-to-know/i-want-to-know-if-there-s-network-latency/) output, latency between network nodes is represented by these colors:

 (low latency)
 (medium latency)
 (high latency)

With the parameters **Trace Route Limit Yellow** and **Trace Route Limit Red** you can specify how many milliseconds of latency should make the lines between network nodes change color from green to yellow and from yellow to red.

# **Graph Image Formats**

With the parameter **Image Format** you can determine whether graphs should be shown as JPEG or PNG images.

| **Image Format**   | **Advantages**                                                                        | **Disadvantages**                                                                                 |
|:-------------------|:--------------------------------------------------------------------------------------|:--------------------------------------------------------------------------------------------------|
| **JPEG**           | 1. Quick generation (typically 1-2 seconds faster than PNG)                           | 1. Large file size (typically three times larger than PNG)<br>2. Image quality not as good as PNG |
| **PNG**            | 1. Small file size (typically three times smaller than JPEG)<br>2. High image quality | 1. Slower generation (typically 1-2 seconds longer than JPEG)                                     |

:::note[Important]
<details>
<summary>Why is graph image file size important?</summary>

Graph images are often used in reports, so the size of the graph image files will also affect the size of reports. If your reports contain many graphs, and you generate the reports often, and you keep the reports for many days, you may accumulate considerable amounts of data.

:::caution
The **Image Format** parameter does not affect [Performance Counters](/performanceguard/technical-reference/concepts/performance-counters/). Interactive graphs are created and shown in a different way than other graphs in the PerformanceGuard web interface  
By changing web interface parameters you can also disable parts of the PerformanceGuard web interface that your organization doesn't use, change [Date and Time](/performanceguard/get-started/how-does-performanceguard-work/date-and-time/), manage log folders and more.
