大家好，又见面了，我是全栈君，今天给大家准备了Idea注册码。
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：

以下是一些代码段：
model
代码语言：javascript复制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
代码语言：javascript复制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)freemind整理的思路中另一些功能没有实现。眼下这个仅仅能算个简单的demon吧，可是基本实现了监控的目的。欢迎大家给我留言！
以下上个django的admin界面截图吧！
