# Generate an ACC allowlist

# Generate an Agent Client Collector allowlist {#ariaid-title1}

Release version: Brazil  
Updated September 10, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Specify the checks to be included in the list of checks that are enabled to run on the agent.

## Before you begin

Role required: agent_client_collector_admin

## About this task

The default allowlist includes all validated checks, and is included in the base system policies. If the allowlist cannot be read correctly, no checks run on the agent.

## Procedure

1. Navigate to AllAgent Client CollectorCheck Definitions.  
   The Check Definitions page appears.
2. In the Related Links section at the bottom of the page, click Generate allow-list content.  
   Note:  
   Alternatively, you can click a check definition or check instance record and click Generate allow-list content to generate a complete allowlist.

   The Agent Client Collector Command Allow-list Generator page appears, with the list of checks scanned from the Command field of the check instance records.

   The values appear with the following attributes:
   {#acc-generate-allow-list__table_kzq_xh2_ylb__entry__2}

   | Attribute | Description |
   |-|-|
   | exec | The executing command. |
   | args | Possible argument strings. |
   | skip_arguments | Boolean. Determines whether to verify that the argument was added to the allowlist. * true: Skips argument validation and checks only for illegal characters, specifically \|;\\\<\>\&'$() * false: Executes argument validation to ensure that the argument is included in the allowlist. If it is not, the command cannot execute. {#acc-generate-allow-list__ul_i1f_m32_ylb} |
   | use_regex | Boolean. Determines whether to evaluate the arg strings as a regular expression. * true: Evaluates each entry in the args array as a regular expression * false: Evaluates each entry in the args array as it is. {#acc-generate-allow-list__ul_dbw_thc_43c} Note: Ensure that the regex is useable in valid JSON format and is golang compatible. |
   | allow_shell | Boolean. Allow for the given entry to be executed in shell mode and for check definitions to default to execv. * true: This allowlist entry permits execution in shell mode. * false: This allowlist entry doesn't permit execution in shell mode. {#acc-generate-allow-list__ul_ht2_m3c_43c} |
   [Table 1. Command attributes]

   {#acc-generate-allow-list__table_kzq_xh2_ylb}
3. Copy the entries you want to include in the allowlist and add them to the agent's check-allow-list.json file, either manually or using an automation tool.  
   The location of this file is indicated in the allow-list parameter of the agent's acc.yml file. The default location is:  
   * Windows: C:\\ProgramData\\ServiceNow\\Agent Client Collector\\check-allow-list.json
   * Linux: /etc/servicenow/agent-client-collector/check-allow-list.json
   {#acc-generate-allow-list__ul_kx2_dvd_dkc}
