# Generate a Pattern allowlist

Generate an allowlist for a selection of patterns, to configure the patterns permitted to run on an agent.

## Before you begin

Ensure that the following plugins are installed on your instance:

-   Discovery \(com.snc.discovery\)
-   Pattern Designer Enhancements \(com.sn\_itom\_pde\)
-   **Pattern Allowlist Generator** available as part of Agent Client Collector for Visibility Content 1.5.0 \(202512\)

Role required: discovery\_admin or agent\_client\_collector\_admin

## Procedure

1.  Navigate to **All** > **Pattern Designer** > **Patterns allowlist for ACC**.

    The **Pattern Allowlist Generator** page appears.

2.  Select the type of pattern selection in the **Pattern Selection** section.

    -   **All patterns**: The allowlist generates for all patterns on the agent.
    -   **Specific patterns**: The allowlist generates on the agent only for the patterns you select.

        After selecting this option, choose the patterns from which you want the allowlist to be generated.

3.  Select **Generate Allowlist**.

4.  Select **Copy** to copy the generated allowlist.

5.  Append the copied allowlist into the existing `check-allow-list.json` allowlist on the agent.

    The patterns specified in the allowlist are permitted to run on the agent.

    The allowlist's default location is:

    -   Windows: `C:\ProgramData\ServiceNow\Agent Client Collector\check-allow-list.json`
    -   Linux: `/etc/servicenow/agent-client-collector/check-allow-list.json`
    **Note:** To generate allowlist for commands nested within EVAL\(\) in a pattern step, ensure the Pattern Designer Enhancements plugin is v3.9.1 or above.


-   **[Define temporary variables for a pattern allowlist](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/it-operations-management/agent-client-collector/define-temp-variables.md)**  
Define temporary variables by assigning values such as executable paths, config file paths, and so forth. Defining temporary variables ensures that runtime commands are successful.
