python 检查进程 python检测进程和端口

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')
