# Service Mapping — Linux servers in services

Use this example to build a Service Mapping query to find all Linux servers in services.

## Before you begin

Role required: none

## About this task

This example Service Mapping query finds all services that include Linux servers. Then, with a simple modification, the query can find all services that do not include a Linux server.

## Procedure

1.  Navigate to **All** > **Configuration** and select **CMDB Query Builder**.

2.  Select **Create new** and then enter `Linux server in services` in the **Name** field.

3.  Choose **Service Mapping Query** and then select **Create**.

4.  In the **CMDB Classes** hierarchy list, locate **Linux Server** and drag it to the canvas.

    **Tip:** Use the search box to find items quickly.

5.  Select **Run**.

    Review the query results. Each row displays the name of a Service Mapping service and the name of a Linux server that is a member of that service.

6.  On the right-side pane, disable **Services Including This Pattern** and then select **Run** again.

    Review the query results. Now, each row displays the name of a Service Mapping service that doesn't include the specified Linux server.
