我按要求分了两大类主机硬件类和应用信息类。主机类主要展示主与机器相关的监控图如网络、硬盘、CPU负载、内存等。应用信息大类又细分为Nginx_PHP、MySQL、Redis等。效果如下：
实现这些图形的分类第一步，数据库表的设计models。
from django.db import models, connection
# Create your models here.

class DrawTreeManager(models.Manager):
def getclass(self, sql):
cursor = connection.cursor()
cursor.execute(sql)
return cursor.fetchall()
class DrawTree(models.Model):
classname = models.CharField(max_length=64)
hostname = models.CharField(max_length=64)
hostid = models.CharField(max_length=8)
graphid = models.CharField(max_length=8)
graphname = models.CharField(max_length=128)
draw = models.CharField(max_length=2)
type = models.CharField(max_length=2)
objects = DrawTreeManager()
def __unicode__(self):
return self.hostname

class DrawGraphsManager(models.Manager):
def getdata(self, sql):
cursor = connection.cursor()
cursor.execute(sql)
return cursor.fetchall()
class DrawGraphs(models.Model):
graphid = models.CharField(max_length=8)
itemid = models.CharField(max_length=8)
itemname = models.CharField(max_length=128)
units = models.CharField(max_length=16, null=True, blank=True)
objects = DrawGraphsManager()
def __unicode__(self):
return self.graphid
#################################################
class DrawDefManager(models.Manager):
def getdata(self, sql):
cursor = connection.cursor()
cursor.execute(sql)
return cursor.fetchall()
class DrawDef(models.Model):
graphid = models.CharField(max_length=8)
cols = models.CharField(max_length=256, null=True, blank=True)
types = models.CharField(max_length=256, null=True, blank=True)
objects = DrawDefManager()
def __unicode__(self):
return self.graphid
DrawGraphs表用来存放每张图的所需的信息图形id（graphid）、每张图形包含的item的id和item的名字（itemid、itemname）。根据一个graphid时能够得到这张图形的所有itemid、itemname、unit(item的计数单位)，itemid主要是用来冲rrd文件中取对应DS的数据（rrd文件中的DS名我是用的itemid），itemname主要显示图形下面布告牌最大值、最小值神马的，unit就是Y轴显示的单位了。
DrawTree表主要用来存放图形的层叠导航信息的。遍历所有的图形，根据图形名的关键字将每幅图归档。classname字段存放每组的组名，硬件数据的组名取Zabbix的默认分组，应用数据的分组是我自定义的分组如Nginx_PHP、Redis、MySQL等分组。hostname字段对应主机名、hostid对应主机id、graphname对应图形名、graphid对应图形id，draw对应图形是否显示的标志位（1显示、0不显示），type代表图形的分类（0代表硬件信息、1代表Nginx_PHP、2代表MySQL以此类推）。
DrawDef表用来存放自定义图形显示所需的信息。graphid字段为需要自定义显示图形的图形id，cols代表需要自定义图形的颜色代码每种颜色用分号隔开，types对应需要自定义的绘图方法如线性（LINE1、LINE2、LINE3）、区块（AREA）等。
更新DrawTree与跟新DrawGraphs记录是同时进行的（为了精简代码和逻辑），views相关的代码是这样的：
def zabbixindex(request):
if request.method == "GET":
for key in request.GET:
value = request.GET[key]
break
if value == "check":
zbx = Zabbix()
groupinfo = zbx.group_get()
hostsinfo = zbx.hostsid_get()
for host in groupinfo:
groupid = host["groupid"]
groupname = host["groupname"]
hostid = host["hostid"]
hostname = ""
for i in hostsinfo:
if i.values()[0] == hostid:
hostname = i.keys()[0]
break
hostgraphs = zbx.hostgraph_get(hostname)
for graph in hostgraphs:
graphid = graph["graphid"]
graphname = graph["name"]
#不存在的图形才更新
#图形展示分类
flag = DrawTree.objects.filter(graphid=graphid)
if not flag:
#更新zabbixapp_drawtree表
draw = "1"
if "PHP-FPM" in graphname or "Nginx" in graphname:
type = "1"
classname = "Nginx_PHP"
elif "MySQL" in graphname or "InnoDB" in graphname:
type = "2"
classname = "MySQL"
elif "Redis" in graphname:
type = "3"
classname = "Redis"
elif "Memcached" in graphname:
type = "4"
classname = "Memcached"
elif "MongoDB" in graphname:
type = "5"
classname = "MongoDB"
else:
classname = groupname
type = "0"
DrawTree.objects.create(classname=classname, hostname=hostname, hostid=hostid, graphid=graphid, graphname=graphname,
draw=draw, type=type)
#更新zabbixapp_drawgraphs表
itemsinfo = zbx.graphitems_get(graphid)
units = itemsinfo[0]["units"]
for item in itemsinfo:
itemid = item["itemid"]
itemname = item["name"]
DrawGraphs.objects.create(graphid=graphid, itemid=itemid, itemname=itemname, units=units)
return HttpResponseRedirect("/graph/zabbix/")
#非get或post请求部分,tree

sql_0 = "select distinct classname from zabbixapp_drawtree where type="0""

tmplist.append(tmp)
typelist1.append({"type":i[0], "host":tmplist, "tflag": chost[2]})
#value = typelist1
avg = {"privatetitle": "Zabbix监控数据展示", "STATIC_URL": "/static", "list0":typelist0, "list1":typelist1}
return render_to_response("zabbixapp/zabbixindex.html", avg)
该视图函数渲染的模板zabbixindex.html写的比较简单，代码是这样的：
{% extends "base.html" %}
{% block title %}{{ privatetitle }}{% endblock %}
{% block thercss %}
{% endblock %}
{% block otherjs %}
{% endblock %}
{% block content %}
{% for i in list0 %}
pse">{{i.type}}
{% for tmp in i.host %}
{{tmp.hostname}}
{% endfor %}
{% endfor %}
{% for i in list1 %}
{{i.type}}
{% for tmp in i.host %}
{{tmp.hostname}}
{% endfor %}
{% endfor %}
新增图形检测
<script type="text/javascript">
//iframe高度自适应
function autoHeight(){
var iframe = document.getElementById("draw");
if(iframe.Document){//ie自有属性
iframe.style.height = iframe.Document.documentElement.scrollHeight;
}else if(iframe.contentDocument){//ie,firefox,chrome,opera,safari
iframe.height = iframe.contentDocument.body.offsetHeight ;
}
}
</script>
{% endblock %}
从ZabbixAPI取图形的各种属性值，经过适当的分类操作后将分类数据在本地落地，然后取落地后的分类数据将硬件和业务信息分类展示出来。
