CMDB Asset Acquisition

Agent (Mode)

1: Each server needs to install agent to achieve fast acquisition speed, simple, resulting in a performance loss gets the asset for each server and has a return value: V=subprocess.getoutput (' dir ') or Ipconfig returned to API  API for storage   (API  1.url  2. Specify the sending data format  3. and has a return value to the client) 2: Scenario: Companies with more services

Client: Import subprocessv1=subprocess.getoutput (' ipconfig ') # print (v1) value1=v1[20:30]  #采集到一套资产v2 = Subprocess.getoutput (' dir ')  #采集到另外一条命令 # Print (v2) value2=v2[0:5] #连接到数据库, write to the database  data to send url= above the URL "http// 127.0.0.1:8000/asset.html "Import requestsresponse=requests.post (url,data={' K1 ': value1, ' K2 ': value2})   # Data sent to the specified URL after sending the data has a return value, received URL to return information print (Response.text)

Server Api:from app01 Import viewsurlpatterns = [    url (R ' ^admin/', admin.site.urls),    url (r ' ^asset.html$ ', Views.asset),]from django.shortcuts import render,httpresponse# Create your views here.def asset (Request):   # Receive messages from users    if Request.method = = "POST":        print (Request.

Paramiko (SSH mode)

Import Paramiko module by remote execution of a command each server needs to install SSH remote process: The central control machine to the server to collect information, collected information returned to the central control machine and then the central control machine to return the information to the API, API received the message and returned to the central control machine to collect the asset information placed in the central control Machine (Paramiko module) v=subprocess.getoutget (' ipconfig ') to get the central control machine acquisition information in the control machine in the information returned to the API, API in the storage advantages: no agent disadvantage: Network Slow application scenario: Fewer servers of the company
