ZabbixAPI+django+nginx简单的二次开发实例（四）
步骤五，图形展示
写一个RRDtool图形展示的脚本，由于要和view.py联动，我放在了appname的文件夹下
cd /API/web/pos/moniter
vim rrddraw.py
#!/usr/bin/env python #coding=utf-8 import rrdtool #ping的图形 def itemping(data): pngname = str(data[‘pname‘]) #图片文件名 start = data[‘stime‘] #起始时间 graphname = str(data[‘hname‘] + " PingCheck " + data[‘flag‘]) #图形标题 unit = ‘ ‘ #单位 lfm = str(data[‘slfm‘]) #x轴的格式 DEF = str(‘DEF:a=‘+data[‘rpath‘]+‘:PING:MIN‘) #数据来源 dtype = str(‘LINE1:a#000000:PING‘) #采用折线的格式 min = ‘GPRINT:a:MIN:Min\:%.2lf %s‘ #文字说明 now = ‘GPRINT:a:LAST:Now\:%.2lf %s‘ #文字说明
#绘图 rrdtool.graph(pngname, "--x-grid", lfm, ‘-w‘, ‘600‘, ‘-h‘, ‘144‘, ‘-l‘,‘0‘, ‘-u‘, ‘2‘, ‘-s‘, start,‘-t‘, graphname, ‘-v‘, unit, DEF, ‘COMMENT: \\n‘, dtype, now, min, ‘COMMENT: \\n‘)
#C盘usage的图形 def itemdiskc(data): pngname = str(data[‘pname‘]) start = data[‘stime‘] graphname = str(data[‘hname‘] + " C:Usage " + data[‘flag‘]) DEF = str(‘DEF:a=‘+data[‘rpath‘]+‘:DiskCUsage:AVERAGE‘) dtype = str("AREA:a#6495ED:DiskCUsage") #采用了区块的格式 war = "HRULE:80#D2691E:Warning" #添加了直线作为警戒线 cti = "HRULE:90#FF0000:Critical" #添加了直线作为故障线 unit = ‘%‘ #单位为百分号 lfm = data[‘slfm‘] max = ‘GPRINT:a:MAX:Max\:%.2lf %s‘ min = ‘GPRINT:a:MIN:Min\:%.2lf %s‘ avg = ‘GPRINT:a:AVERAGE:Avg\:%.2lf %s‘ now = ‘GPRINT:a:LAST:Now\:%.2lf %s‘ rrdtool.graph(pngname, "--x-grid", lfm, ‘-w‘, ‘600‘, ‘-h‘, ‘144‘, ‘-l‘,‘0‘, ‘-u‘, ‘100‘, ‘-s‘, start,‘-t‘, graphname, ‘-v‘, unit, DEF, war, cti, ‘COMMENT: \\n‘, dtype, now, avg, min, max, ‘COMMENT: \\n‘)
#D盘usage的图形 def itemdiskd(data): pngname = str(data[‘pname‘]) start = data[‘stime‘] graphname = str(data[‘hname‘] + ‘ D:Usage ‘ + data[‘flag‘]) DEF = str(‘DEF:a=‘+data[‘rpath‘]+‘:DiskDUsage:AVERAGE‘) dtype = str("AREA:a#6495ED:DiskDUsage") war = "HRULE:80#D2691E:Warning" cti = "HRULE:90#FF0000:Critical" unit = ‘%‘ lfm = data[‘slfm‘] max = ‘GPRINT:a:MAX:Max\:%.2lf %s‘ min = ‘GPRINT:a:MIN:Min\:%.2lf %s‘ avg = ‘GPRINT:a:AVERAGE:Avg\:%.2lf %s‘ now = ‘GPRINT:a:LAST:Now\:%.2lf %s‘ rrdtool.graph(pngname, "--x-grid", lfm, ‘-w‘, ‘600‘, ‘-h‘, ‘144‘, ‘-l‘,‘0‘, ‘-u‘, ‘100‘, ‘-s‘, start,‘-t‘, graphname, ‘-v‘, unit, DEF, war, cti, ‘COMMENT: \\n‘, dtype, now, avg, min, max, ‘COMMENT: \\n‘)
这边并不是一直去更新图形，而是根据用户访问来实时生成图形
编辑view.py
vim view.py

制作网页
mkdir /API/web/pos/moniter/templates/home
新建draw.html作为展示一日图形的网页
<!DOCTYPE html> {% load staticfiles %} <html> <head> <title>{{ privatetitle }}</title> <link rel="stylesheet" type="text/css" href="{% static ‘css/bootstrap.css‘ %}" /> <script src="{% static ‘/scripts/jquery.min.js‘ %]"></script> <script src="{% static ‘/bootstrap/js/bootstrap.min.js‘ %]"></script> </head> <body> <ol class="breadcrumb"> <li><b>Daily</b></li> <li><a href="../drawweek.html?uid={{uid}}">Weekly</a></li> <li><a href="../drawmonth.html?uid={{uid}}">Monthly</a></li> </ol> {% for png in pngs %} <p> <img src="{{ png.pngpath }}" class="img-responsive" alt="Responsive image"> </p> {% endfor %} </body> </html>
新建drawweek.html作为展示一周图形的网页
<!DOCTYPE html> {% load staticfiles %} <html> <head> <title>{{ privatetitle }}</title> <link rel="stylesheet" type="text/css" href="{% static ‘css/bootstrap.css‘ %}" /> <script src="{% static ‘/scripts/jquery.min.js‘ %]"></script> <script src="{% static ‘/bootstrap/js/bootstrap.min.js‘ %]"></script> </head> <body> <ol class="breadcrumb"> <li><a href="../draw.html?uid={{uid}}">Daily</a></li> <li><b>Weekly</b></li> <li><a href="../drawmonth.htmli?uid={{uid}}">Monthly</a></li> </ol> {% for png in pngs %} <p> <img src="{{ png.pngpath }}" class="img-responsive" alt="Responsive image"> </p> {% endfor %} </body> </html>
新建drawmonth.html作为展示一周图形的网页
<!DOCTYPE html> {% load staticfiles %} <html> <head> <title>{{ privatetitle }}</title> <link rel="stylesheet" type="text/css" href="{% static ‘css/bootstrap.css‘ %}" /> <script src="{% static ‘/scripts/jquery.min.js‘ %]"></script> <script src="{% static ‘/bootstrap/js/bootstrap.min.js‘ %]"></script> </head> <body> <ol class="breadcrumb"> <li><a href="../draw.html?uid={{uid}}">Daily</a></li> <li><a href="../drawweek.html?uid={{uid}}">Weekly</a></li> <li><b>Monthly</b></li> </ol> {% for png in pngs %} <p> <img src="{{ png.pngpath }}" class="img-responsive" alt="Responsive image"> </p> {% endfor %} </body> </html>
修改url.py
cd /API/web/pos/pos
vim urls.py
from django.conf.urls import url from django.contrib import admin from moniter import views as m_views urlpatterns = [ url(r‘^admin/‘, admin.site.urls), url(r‘^home/‘, m_views.home, name=‘home‘), #这里开始是本次新加的 #主页上的url跳转和图形页面点daily的url跳转不是很搞的明白，干脆两种跳转都指向同一个页面 url(r‘^draw.html‘, m_views.zabbixdraw), url(r‘^draw/‘, m_views.zabbixdraw), url(r‘^drawweek.html‘, m_views.zabbixdraww), url(r‘^drawmonth.html‘, m_views.zabbixdrawm), ]
重启project
supervisorctl -c /etc/supervisord.conf restart pos
打开网站，点击任何一个host会弹出一日图形展示的页面，点击weekly和monthly会分别展示一周和一月的图形。(刚设置好的时候可能rrd里面没有多少数据，放个几天再去看就会有了)
