zabbix_agent port auto-discovery service

Application Background:

      zabbix monitoring system introduction and installation, refer to Daniel operation and maintenance of survival time , here not long-winded

To zabbix-agent terminal can automatically report server service port to zabbix server end, port monitor their survival if available,

With the following script: service_scan.py agent deployed to end /usr/local/zabbix-agent/bin/service_scan.py

Deployment Readiness:

1. service_scan.py script library in accordance with psutil lazy python2.7 version,
2. Python2.7 version needs to be installed in the agent side,
3. Installation Related psutil library with python2.7

1	/usr/local/python27/bin/pip  install  psutil

　　

Server port auto-discovery script:  service_scan.py
