用 Python 脚本对 Linux 服务器的监控

Python  监控脚本（硬盘、cpu、内存、网卡、进程）

 

#磁盘使用率 disk = psutil.disk_partitions() for i in disk:     print "磁盘：%s   分区格式:%s"%(i.device,i.fstype)     disk_use = psutil.disk_usage(i.device)     print "使用了：%sM,空闲：%sM,总共：%sM,使用率33[1;31;42m%s%%33[0m,"%(disk_use.used/1024/1024,disk_use.free/1024/1024,disk_use.total/1024/1024,disk_use.percent)

 

#网络使用率

1．  监控服务器cpu使用率

def cpu():     while True:         time.sleep(1)         cpu_liyonglv = psutil.cpu_percent()         print "当前cpu利用率：33[1;31;42m%s%%33[0m"%cpu_liyonglv         if cpu_liyonglv >15.0:             baojing() def baojing():     i = 0     while i < 10 :         i += 1         time.sleep(0.5)         winsound.PlaySound("ALARM8",winsound.SND_ALIAS) cpu()

2．  监控服务器内存使用率

memory = psutil.virtual_memory() print memory.used print memory.total ab = float(memory.used)/float(memory.total)*100 print "%.2f%%"%ab print psutil.swap_memory()

3．  监控服务器网卡使用率

#网络使用率 count = psutil.net_io_counters() print "发送字节数：33[1;31;42m%s33[0mbytes,接收字节数：33[1;31;42m%s33[0mbytes,发送包数：%s,接收包数%s"%(count.bytes_sent,count.bytes_recv,count.packets_sent,count.packets_recv)
users = psutil.users() print "当前登录用户：",users[0].name #时间 curent_time = psutil.boot_time()
curent_time_1 = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime(curent_time)) print curent_time_1

4．  进程监控

脚本如下：

#读取进程pid，名称，可执行路径 
pid = psutil.pids() 
for k,i in enumerate(pid): 
    try: 
        proc  = psutil.Process(i) 
        print k,i,"%.2f%%"%(proc.memory_percent()),"%",proc.name(),proc.exe() 
 
    except psutil.AccessDenied : 
        print "psutil.AccessDenied"
