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')
