A: Agent way
Principle: Each server agent installed on the client, asset information regularly sent to the specified database.
Advantages: speed.
Disadvantages: need more software installed on a server
. 1 Import The subprocess 2 Import Requests . 3 # PIP3 the install Requests . 4 . 5 # ################## data acquisition ################ ## . 6 # Result = subprocess.getoutput ( 'the ipconfig') . 7 # Result regular process of acquiring the desired data . 8 . 9 # finishing asset information 10 # data_dict = { . 11 # 'NIC': {}, 12 is # 'Disk': { }, 13 is # 'MEM': {} 14 # } 15 16 # ################## transmission data ############## #### 17 # requests.post('http://www.127.0.0.1:8000/assets.html',data=data_dict)
Two: SSH way
Principle: active intermediate component assets acquired information to the server, and then add data to the database by the middleware (through API)
Pros: do not install the client server-side software
Cons: Slow

Three: Saltstack way
Principle: and a second similar, but put the request to the queue based on third-party software, middleware, the client receives a request to stop the queue, upon receiving the request, the server parses find the need to return to their asset information on the implementation of command and returns the result into another queue, fetching data from the intermediate queue result, and then stored in the database through the API
Advantages: speed, low development costs
Cons: dependent on third-party software

Four: puppet
Principle: the server sends data to the middleware, middleware API data stored in the database.
Advantages: automatically provides data to the middleware server
Disadvantages: the use of middleware puppet ruby development
