+Table Size Retriever – ServiceNow
+Overview
+
+This script retrieves the size of any table in your ServiceNow instance in gigabytes and provides a fallback estimate if metadata is not available. It also logs the total number of records in the table.
+
+This is useful for instance management, capacity planning, and gaining insights into table sizes without manually inspecting each table.
+
+Features
+
+Retrieves the official table size from the sys_physical_table_stats table if available.
+
+Falls back to a size estimate based on record count when metadata is missing.
+
+Logs the number of records in the table.
+
+Can be used with any table by changing the tableName variable.
+
+Fully compatible with Background Scripts.
+
+Configuration
+
+Table Name: Set the tableName variable to the table you want to check.
+
+var tableName = 'task'; // Replace with any table name
+
+How It Works
+
+Queries the sys_physical_table_stats table for the specified table name.
+
+If the table exists in metadata, retrieves the size in gigabytes.
+
+If metadata is not available, estimates the table size based on record count (assuming 1 KB per record).
+
+Logs the table size (official or estimated) in GB.
+
+Separately retrieves and logs the total number of records in the table.
+
+Usage
+
+Navigate to System Definition → Scripts – Background in your ServiceNow instance.
+
+Copy and paste the script.
+
+Update the tableName variable as needed.
+
+Click Run Script.
+
+Check the system logs to view the table size and record count.
