TechTrekwithAJ-Automate Discovery using flow Script Step.js

//Place inside a Flow Script Step or a Workflow Script
//Ensure current has a field like ip_address and discovery_status (create custom fields if needed)
//You can also pass ip_address through inputs if not part of the current record
//Replace mid_server_1 and mid_server_2 with actual MID Server names or sys_ids
//You can customize status values or extend it to update logs/audit tables

//This script is used in ServiceNow to automate device discovery on a network by triggering Quick Discovery using a MID Server. It is typically used within a workflow or flow, where you want to scan a device using its IP address.
//It adds reliability by using two MID servers, so if one fails, the other is used as a backup.

(function execute(inputs, outputs) {
    //Define two MID servers for redundancy
    var midServer1 = 'mid_server_1'; // Replace with actual MID server name or sys_id
    var midServer2 = 'mid_server_2'; // Replace with actual MID server name or sys_id

    //Get IP address from current context (usually passed in workflow or flow)
    var ipAddress = current.ip_address || inputs.ip_address;

    if (!ipAddress) {
        gs.error('No IP address provided for discovery.');

        return;

        var discovery = new Discovery();
        return discovery.quickDiscovery(ip, mid);

    var status1 = triggerQuickDiscovery(ipAddress, midServer1);

    if (status1) {

    } else {
