Script to Trigger Quick Discovery from Workflow / Flow

ITOM/Discovery/README.md

@@ -0,0 +1,13 @@
+This code snippet automates the discovery of devices in ServiceNow using MID (Management, Instrumentation, and Discovery) servers by triggering Quick Discovery through a workflow. The code can also be modified for different workflows/ flows as needed.
+
+Key features include:
+
+MID Server Setup: It defines two MID servers to ensure redundancy, which improves the chances of successfully finding devices.
+
+IP Address Retrieval: The code retrieves the IP address to be scanned from the current workflow context.
+
+Discovery Process:
+
+It creates a Discovery object to initiate the process. The script first attempts to find the device using the first MID server. If that fails, it logs a message and tries again with the second MID server. Logging and Status Update: After the discovery attempts, the script logs the results and updates the current context with the discovery status.
+
+This code enhances device discovery in ServiceNow, making the process more reliable by utilizing multiple MID servers.
