Вот несколько методов, которые вы можете использовать для выполнения операции ping с помощью PyMongo:

1. Использование метода ping():

   from pymongo import MongoClient
   client = MongoClient('mongodb://localhost:27017')
   db = client.test
   # Ping the MongoDB server
   result = db.command('ping')
   print(result)

2. Проверка состояния подключения:

   from pymongo import MongoClient
   client = MongoClient('mongodb://localhost:27017')
   db = client.test
   # Check the connection status
   try:
      client.admin.command('ismaster')
      print("Server is available")
   except Exception as e:
      print("Server is not available:", str(e))

3. Использование метода server_info():

   from pymongo import MongoClient
   client = MongoClient('mongodb://localhost:27017')
   db = client.test
   # Get server information
   server_info = db.command('serverStatus')
   print(server_info)

4. Использование свойства is_primary:

   from pymongo import MongoClient
   client = MongoClient('mongodb://localhost:27017')
   db = client.test
   # Check if the connected server is the primary server
   if client.is_primary:
      print("Connected to primary server")
   else:
      print("Connected to secondary server")
