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
    • 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.

ParameterValue
CONNECT\_WITHOUT\_MIDSpecify true to enable MID-less installation. If you don't specify a value, the regular MID Server websocket installation is invoked.
ACC\_CNCPublic gateway endpoint for Agent Client Collector that you can specify.
REGISTRATION\_KEYActive and valid agent registration key for the agent to communicate with.
INSTANCE\_URLServiceNow instance that the agent is registering with.
ACC\_ALLOW\_LIST

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.

ACC\_VALIDATE\_SIG

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.

  1. Configure the ServiceNow sudoers file.

    For details on the procedure, see Configure ServiceNow sudoers file.
