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-8import psutilimport sysimport 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PIDdef 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')
