# Install ACC for DEX on macOS

Install Agent Client Collector \(ACC\) to monitor and collect data in a centralized and organized manner, provide insights into system performance, identify issues, and enable proactive maintenance.

## Before you begin

-   Install the ITOM Cloud Services Core \(sn\_itom\_cloud\_svc\) plugin.
-   Onboard your instance to use ITOM Cloud Services. For details, contact Customer Support.
-   Configure an agent registration key.
-   Role required: root

## Procedure

1.  Retrieve the agent registration key:

    1.  Navigate to **All** > **Agent Client Collector** > **Deployment** > **Agent Registration Key**.

    2.  Select the relevant agent registration key.

    3.  Copy the registration key value and store it in a place where you can easily retrieve it when needed.

2.  Retrieve the publicly accessible gateway URL, based on your location:

    -   AMER \(Americas\): `itomcnc-prod-gateway.amer.sncapps.service-now.com:443`
    -   EMEA \(Europe\): `itomcnc-prod-gateway.emea.sncapps.service-now.com:443`
    -   APAC \(Asia Pacific\): `itomcnc-prod-gateway.apac.sncapps.service-now.com:443`
3.  On the server where you’re installing the Agent Client Collector, enter the following command:

    ```
    CONNECT_WITHOUT_MID="true" ACC_CNC="<gateway_endpoint>" REGISTRATION_KEY="<registration_key>" INSTANCE_URL="https://<instance_url>" bash -c "$(curl -L https://<instance_url>/api/sn_agent/agents/install_agent)"
    ```

    The following table describes the parameter values in the command.

<table id="table_i4m_yjq_wxb"><thead><tr><th>

Parameter

</th><th>

Value

</th></tr></thead><tbody><tr><td>

CONNECT\_WITHOUT\_MID

</td><td>

Specify **true** to enable MID-less installation. If you don't specify a value, the regular MID Server websocket installation is invoked.

</td></tr><tr><td>

ACC\_CNC

</td><td>

Public gateway endpoint for Agent Client Collector that you can specify.

</td></tr><tr><td>

REGISTRATION\_KEY

</td><td>

Active and valid agent registration key for the agent to communicate with.

</td></tr><tr><td>

INSTANCE\_URL

</td><td>

ServiceNow instance that the agent is registering with.

</td></tr><tr><td>

ACC\_ALLOW\_LIST

</td><td>

Optional **ACC\_ALLOW\_LIST=0** string that you can add to disable the allow list.Default: The allow list is enabled.

**Note:** When you disable the allow list, you compromise your system's security. This action is intended as a temporary measure while you're updating the allow list. After you complete the update, remove **ACC\_ALLOW\_LIST=0** from the command line.

</td></tr><tr><td>

ACC\_VALIDATE\_SIG

</td><td>

Optional **ACC\_VALIDATE\_SIG=0** string that you can add to disable the verification of the installer certification validation. Default: Validation is enabled.

**Note:** Disable the certification validation only when you're using non-standard signature validation tools.

</td></tr></tbody>
</table>4.  Configure the ServiceNow sudoers file.
