python监控nginx端口和进程状态

本文实例为大家分享了python监控nginx端口和进程状态的具体代码，供大家参考，具体内容如下

#!/usr/local/bin/python
# coding:utf-8
import psutil
import sys
import os

# 获取主机名称
def hostname():
 sys = os.name
 if sys == 'nt':
   hostname = os.getenv('computername')
   return hostname
 elif sys == 'posix':
   host = os.popen('echo $HOSTNAME')
   try:
     hostname = host.read()
     return hostname
   finally:
     host.close()
 else:
   return 'Unkwon hostname'

# 获取进程状态
def processStatus(processName):
 pids = psutil.pids()   #获取主机所有的PID
 a = 1
 for pid in pids:      #对所有PID进行循环
   p = psutil.Process(pid)  #实例化进程对象
   if p.name() == processName:   #判断实例进程名与输入的进程名是否一致（判断进程是否存活）
     print (a)   #返回1，进程存活
     a += 1
 if a == 1:
   print (0)         #返回0，进程逝去

# 获取进程PID
def processPID(processName):
 pids = psutil.pids()
 for pid in pids:
   p = psutil.Process(pid)
   if p.name() == processName:
     return pid
     return True # 如果找到该进程则打印它的PID，返回true
 else:
   print('找不到进程'+processName)
   return False # 没有找到该进程，返回false

# 获取进程的端口号
def processPort(pid):
   p = psutil.Process(pid)
   data=p.connections()
   data_listen=[x for x in data if 'LISTEN' in x ]
   # pid_port=[]
   # for port in data_listen:
   #   pid_port.append((port.laddr.port))
   # return list(set(pid_port))
   return list(data_listen[0][3])[1]

hostname=hostname().strip()
PID=processPID('nginx')
port=processPort(PID)

json_data = [
{"name": hostname+'-nginx', "port": port,"host_ip":LOCAL_IP,"PID":PID}
]

AutoDiscoveryJson(json_data, object_id='HOST')
