Zabbix Python API Application Combat

Do the monitoring students should know that the company IDC room often has shelves, shelves, repair and scrap server. If the number of servers is very large, it is easy to cause monitoring omission.
Big Internet companies integrate surveillance systems and CMDB (Asset Management System | Configuration Management database systems) together, and when a new machine is listed, the CMDB will record relevant information, Zabbix according to the information in the CMDB automatically link related modules, add | Delete monitoring. Many small companies do not have an asset management system, but the person responsible for monitoring should know what new machines are on the shelves every day, ensuring that they can be added to the Zabbix Monitor.
First of all, let's talk about scripting ideas:
1) scan the network segment with the Nmap tool to scan the IP address that has been used.
2) through Nmap detection has been scanned IP 3389 or 22 port is open, can judge those things Windows machine, those are Linux machines.
3) under Linux, find the Linux hostname via the SSH + hostname command.
4) under Windows, locate the Windows host name by using the NMBLOOKUP-A command.
5) Read the scan result file with the Python script and write the hostname to the list.
6) Use the Zabbix Python API to invoke the monitored host name and write it to the list.
7) Two lists Intersect, using a for loop to determine which host names are not monitored.
8) Email Notification supervisor.

Below I share the Python script I wrote, where scan_machine.sh is the script I wrote about Nmap scanning with the shell, Scan_hostname.log is the result of Nmap scan, the content is the IP host name.

Add the script to Crontab, and each will receive information about those hosts that are not adding monitoring.

Summarize:

1) Zabbix API related information can view the official details, can not read English http://paperplane.ruhoh.com/zabbix/intro-to-zabbix-api/this article.

2) through the script can know that those hosts do not add monitoring, hope to help you, if there is a better solution to welcome a lot of communication.
