Summary

Added new documentation page for the $currentOp aggregation stage in Amazon DocumentDB, including parameters, MongoDB shell example, and code examples in Node.js and Python

Security assessment

This change adds documentation for a monitoring feature ($currentOp) that allows viewing currently running operations. While monitoring can be part of security best practices, there is no evidence this addresses a specific security vulnerability or incident. The documentation is purely instructional for a database operation monitoring feature.

+# $currentOp
+
+The `$currentOp` aggregation stage returns information about currently running operations in the database. This stage is useful for monitoring active queries and operations in an aggregation pipeline.
+
+**Parameters**
+
+  * `allUsers` (optional): When set to `true`, returns operations for all users. Default is `false`.
+
+  * `idleConnections` (optional): When set to `true`, includes idle connections. Default is `false`.
+
+  * `idleCursors` (optional): When set to `true`, includes information about idle cursors. Default is `false`.
+
+  * `idleSessions` (optional): When set to `true`, includes information about idle sessions. Default is `true`.
+
+  * `localOps` (optional): When set to `true`, includes local operations. Default is `false`.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates using the `$currentOp` aggregation stage to retrieve information about active read operations.
+
+**Query example**
+    
+    
+    db.aggregate([
+      { $currentOp: { allUsers: true, idleConnections: false } },
+      { $match: { op: "query" } }
+    ])
+
+**Output**
+    
+    
+    [
+      {
+        "opid": "12345",
+        "active": true,
+        "op": "query",
+        "ns": "test.users",
+        "secs_running": 2
+      }
+    ]

+
+Node.js
+    
+    
+    
+    const { MongoClient } = require('mongodb');
+    
+    async function example() {
+      const client = await MongoClient.connect('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false');
+      const db = client.db('admin');
+    
+      const result = await db.aggregate([
+        { $currentOp: { allUsers: true, idleConnections: false } },
+        { $match: { op: "query" } }
+      ]).toArray();
+    
+      console.log(result);
+      await client.close();
+    }
+    
+    example();
+
+Python
+    
+    
+    
+    from pymongo import MongoClient

+        db = client['admin']
+    
+        result = list(db.aggregate([
+            { '$currentOp': { 'allUsers': True, 'idleConnections': False } },
+            { '$match': { 'op': 'query' } }
