# Parameters and General Settings

> Configure the PerformanceGuard services — display, frontend, notification and more — under Administration, Setup, Parameters.

Product: PerformanceGuard — a separate CapaSystems product; do not apply this page to any other.

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

If you select **Administration > Setup > Parameters**, you can customize and configure the PerformanceGuard services: **Display** (that is web interface-related settings), **Frontend**, **Notification** (that is Backendserver-related settings), **Common** (that is parameters shared between services), **Status**, **Date and Time**, and **System Properties**.

Read more about the effect of parameters in the **Parameter description** column on each of the tabs. If you're in doubt about what will happen if you change a value, contact your PerformanceGuard consultant.

:::caution
After you have changed and saved the values of a service, you must restart the service in question for your changes to take effect.
:::

:::tip
If you think about changing date and time format parameters (you can do that on the **Common** and **Display** tabs), read [Date and Time](/performanceguard/get-started/how-does-performanceguard-work/date-and-time/) first.

# **If You Want DNS to Resolve IP Addresses**

On the **Display** tab, there's a parameter called **DNS server ip-address**. You use that parameter to specify one or more DNS servers if you want DNS to help PerformanceGuard resolve server IP addresses to hostnames.

If you want to specify multiple DNS servers, you must separate the IP addresses with commas, but it's important that you don't use spaces.

:::note[Important]
**Example:** 10.10.10.10,20.20.20.20 will work, because there's no space between the two IP addresses. 10.10.10.10, 20.20.20.20 will *not* work because of the space between the two IP addresses.

# **Some Parameters Overlap with Agent Configuration Group Parameters**

On the **Status** tab there are some parameters that you can also specify as part of the [Agent Configuration Group Settings](/performanceguard/administration/manage-agent-configuration-groups/agent-configuration-group-settings/). If the value of such a parameter isn't the same on the **Status** tab and in the agent group configuration settings, PerformanceGuard will always use the **highest** value.

These are the parameters that overlap:
