使用python+django+twistd 开发自己的操作和维护系统的一个

yxwkaifa 2015-07-04 原文

许多开源操作系统和维护系统，例nagios、zabbix、cati等等，但是，当他们得到的时间自己的个性化操作和维护需求，始终无力！

最近的一项研究python。因此，我们认为python+django+twisted要定制一个完全个性化的操作和维护系统。

有几个基本的功能：监控、分析、报警、更甚者直接依据分析的结果进行反应操作。而以上几点通过上述的框架能够比較easy的实现。

以下上图说明：

使用freemind整理了下思路：

以下是一些代码段，完整的代码下载见文档底部：

Server：

#!/usr/bin/env python
#coding:utf-8
__author__ = 'dwj'
from twisted.internet.protocol import ServerFactory
from twisted.protocols import basic
import cx_Oracle
from twisted.application import service, internet
class Mornitor_Protocol(basic.LineReceiver):
def __init__(self):
#
_oracle_conn=cx_Oracle.connect('xxxx', 'xxxx', '192.168.7.17/test', threaded=True)
_oracle_conn.autocommit = True
self.cur = _oracle_conn.cursor()
self._oracle_conn=_oracle_conn
def ruku(self, line):
ip=self.transport.getPeer().host
#获取clientIP
line=line.split(':::')
#使用：：：切割原始数据
if line[1] in ['cpu', 'mem', 'disk', 'tcp', 'net', 'process_down']:
#依据数据包头来确定使用insert还是update。当是tcp包头的时候插入，其余的更新
if line[1] == 'tcp':
sql = "insert into MORNITOR_BASICINFO (ipadd,time,tcp) values (\'%s\',\'%s\',\'%s\')"%(ip,line[0],line[3])
print sql
self.cur.execute(sql)
else:
line_again = line[3].split('::')
sql = 'update MORNITOR_BASICINFO set %s=\'%s\',%s=\'%s\' where ipadd=\'%s\' and time=\'%s\''%(line[1],line_again[0],line[2],line_again[1],ip,line[0])
print sql
self.cur.execute(sql)
def connectionMade(self):
print 'Connected!'
def lineReceived(self, line):
print line
self.ruku(line)
#接受到数据之后运行入库操作。
def connectionLost(self, reason='connectionDone'):
self._oracle_conn.close()
print 'The db is close... ok!'
class Mornitor_Factory(ServerFactory):
#还没想好要初始化什么
def __init__(self,service):
self.service = service
protocol = Mornitor_Protocol
class Fish_Service(service.Service):
def __init__(self):
pass
def startService(self):
service.Service.startService(self) #什么都不做，開始服务
# def stopService(self):
# return self._port.stopListening()
#配置參数
port = 10000
iface = '127.0.0.1'
top_server = service.MultiService() #定义服务容器
fish_server = Fish_Service() #实例化我们的服务
fish_server.setServiceParent(top_server) #把自己定义的服务增加到服务容器
factory = Mornitor_Factory(Fish_Service) #工厂化服务
tcp_server = internet.TCPServer(port, factory, interface=iface) #定义tcp服务
tcp_server.setServiceParent(top_server) #把tcp服务增加到服务容器
application = service.Application('Fish_Service') #给应用起个名字
top_server.setServiceParent(application) #把服务容器丢到应用中去

Client端

from twisted.protocols import basic
from twisted.internet import protocol, defer, task
import Get_basic_info_2 as Huoqu
import guardian as shouhu
import time
from twisted.application import service, internet
class Monitor_Protocol(basic.LineReceiver):
#自定义客户端和服务端的连接协议。从basic的line继承
def __init__(self):
#
pass
@staticmethod
def huoqu_shuju():
#定义一个函数获取本机的一些状态
now = str(time.strftime('%Y-%m-%d %H:%M:%S'))
def add_tag(source, tag1, tag2 = 'none'):
#定义格式化字符串函数
return ':::'.join([now, tag1, tag2, source])
#使用：：：分隔时间、简单信息、具体信息、原始信息
tcp = add_tag(Huoqu.net_tcp(), 'tcp')
cpu = add_tag(Huoqu.cpu(), 'cpu', 'cpu_detail')
mem = add_tag(Huoqu.mem(), 'mem', 'mem_detail')
disk = add_tag(Huoqu.disk_usage(), 'disk', 'disk_detail')
net = add_tag(Huoqu.net_rate(), 'net', 'net_detail')
process = add_tag(shouhu.check_alive(), 'process_down', 'process_alived')
result = (tcp, cpu, mem, disk, net, process, )
d = defer.Deferred()
#使用defered返回结果
d.callback(result)
return d
def xunhuan(self, list):
#定义循环发送函数
for i in list:
self.sendLine(i)
def fasong(self):
#定义程序执行顺序，取得信息后用callback交给发送函数发送
self.huoqu_shuju().addCallback(self.xunhuan)
def loop(self):
#使用twist内置的循环函数定义几秒监控数据传送到服务端
l = task.LoopingCall(self.fasong)
l.start(1)
def connectionMade(self):
#覆盖协议的connectmade函数。定义于服务端的连接建立后開始循环
print 'Connected!......ok!'
self.loop()
def lineReceived(self, line):
#必须覆盖接受函数，否则twist会报not importent错误！
pass
class Moinitor_client_factory(protocol.ReconnectingClientFactory):
def __init__(self, service):
#还没想要要写什么
self.service = service
protocol = Monitor_Protocol
class Client_Service(service.Service):
def __init__(self):
pass
def startService(self):
service.Service.startService(self)
#配置文件開始
port = 10000
host = '127.0.0.1'
#守护进程
top_service = service.MultiService() #定义服务容器
client_service = Client_Service() #实例化服务类
client_service.setServiceParent(top_service) #把自定义的服务丢到服务容器中
factory = Moinitor_client_factory(client_service) #定义服务工厂化
tcp_service = internet.TCPClient(host, port, factory) #定义tcp连接的服务
tcp_service.setServiceParent(top_service) #把tcp服务丢到服务容器中去
application = service.Application('Fish_Service') #定义应用名字
top_service.setServiceParent(application) #把服务容器丢到应用中去

一些自己定义监控程序是否存活的脚本：

program = {'nginx': ['/opt/nginx/logs/nginx.pid', '/opt/nginx/sbin/nginx'],
'rsync-C': ['/var/run/rsyncd.pid', 'rsync --daemon'],
}
def main():
for k in program:
a = get_pid(k, program[k][0])
if isinstance(a, tuple):
print '%s is not running!' % k
print 'Start the program by Horland_guardian!'
subprocess.call(program[k][1], shell=True)
else:
print 'The %s is running!' % k
def check_alive():
l_lived = []
l_downed = []
for k in program:
a = get_pid(k, program[k][0])
if isinstance(a, tuple):
l_downed.append(k)
else:
l_lived.append(k)
process_alived = ' '.join(l_lived)
process_down = ' '.join(l_downed)
return '::'.join([process_down, process_alived])

django的使用眼下仅仅须要使用到admin模块就能够。

以下是一些代码段：

model

class BasicInfo(models.Model):
ipadd = models.IPAddressField(verbose_name = u'IP地址')
time = models.CharField(max_length=50, verbose_name = u'时间')
cpu = models.CharField(max_length=255, blank=True, verbose_name = u'CPU%')
cpu_detail = models.CharField(max_length=255, blank=True, verbose_name = u'CPU详情')
mem = models.CharField(max_length=255, blank=True, verbose_name = u'内存%')
mem_detail = models.CharField(max_length=255, blank=True, verbose_name = u'内存详情')
disk = models.CharField(max_length=255, blank=True, verbose_name = u'磁盘%')
disk_detail = models.CharField(max_length=255, blank=True, verbose_name = u'磁盘详情')
net = models.CharField(max_length=255, blank=True, verbose_name = u'流量 bytes/s')
net_detail = models.CharField(max_length=1000, blank=True, verbose_name = u'流量详情')
tcp = models.CharField(max_length=255, blank=True, verbose_name = u'tcp连接状态')
process_down = models.CharField(max_length=255, blank=True, verbose_name = u'DOWN-进程')
process_alived = models.CharField(max_length=255, blank=True, verbose_name = u'Process_UP')
def Process_DOWN(self):
return '<span style="color: #%s;">%s</span>' % ('ff0000', self.process_down) #拓机的进程用红色标识
Process_DOWN.allow_tags = True

注冊到admin

class BasicInfo_admin(admin.ModelAdmin):
list_display = ('time', 'cpu', 'cpu_detail', 'mem', 'mem_detail', 'disk', 'disk_detail', 'net', 'net_detail', 'tcp', 'Process_DOWN', 'process_alived')
list_filter = ('ipadd', )
admin.site.register(BasicInfo, BasicInfo_admin)
