Test Agent Client Collector connectivity

Test the Agent Client Collector (ACC) connectivity to identify any proxy issues.

Before you begin

Note: SSL inspection isn’t supported for DEX.

Role required: agent_client_collector_admin

Procedure

  1. Gather the following information to test communication between the ACC and ServiceNow shared services:

    1. Copy CNC certificates from the agent to a new folder:

      OSCopy fromPaste to
      WindowsC:\ProgramData\ServiceNow\agent-client-collector\config\cert\cncAny temp folder
      macOS/Library/Application Support/ServiceNow/agent-client-collector/cert/cncAny temp folder
    2. Copy the 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
        1. Navigate to All > sys_attachment.list.
    3. Under Attachments, select File name in the drop-down menu and search for acc-dex-common.tar.gz.

    4. Retrieve the following parameters:

      • Record sys_id
      • Hash id
Image omitted: sys\_attachments\_table.png
Attachments table with the acc-dex-common.tar.gz record
  1. Test the connection by running one of the following commands from the temp folder that you created:

    • Without Proxy: curl --verbose --output acc-dex-common.tar.gz --cert cnc_chain.crt --key priv_key.pem https://<ITOM-Gateway-URL>/content/v1/assets/<attachment_sys_id>/<hash_id>
    • With Proxy: curl --verbose –-proxy <HOST_NAME>:<PORT> --output acc-dex-common.tar.gz --cert cnc_chain.crt --key priv_key.pem https://<ITOM-Gateway-URL>/content/v1/assets/<attachment_sys_id>/<hash_id> The command output is generated.
  2. Confirm that the Content length in the command output matches the Size bytes in the Attachments table (sys_attachment).

    See the preceding image for the location of the Size bytes information in the Attachments table.

Fix your proxy issues if the command output doesn't match the Attachments table entries.
