You May Like我们大概了解了怎么对台主机进行监控,主要步骤设计到添加主机,并且为主机添加监控项,这里主要为item,然后在item的基础上对item进行绘图并且通过screen的方式把不同的监控图像汇总到一张screen上。通过对quick章节我们认识到item监控项在zabbix中是非常重要的,而item的监控是通过key来定义的,key又分为系统预定义好的key和自定义的key组成,这一节,我们通过对zabbix预定义的内存key来了解一下key到底是怎么组成和怎么使用的。
vm.memory.size[&mode&]
total (default), active,anon,
&buffers, cached, exec, file, free, inactive
&pinned, shared, wired, used, pused, available, pavailable
Numeric (unsigned)
&vm.memory.size[total]
vm.memory.size[total]
vm.memory.size[total]
vm.memory.size[total]
system.swap.in[&device&,&type&]
Type:count,sectors pages
Numeric (unsigned)
system.swap.in[,pages]
system.swap.out[&device&,&type&]
Type:count,sectors pages
Numeric (unsigned)
system.swap.out[,pages]
上图为所有与内存相关的key已经与之相对应的参数,单位,例子等相关信息,下面我将通过一个例子来展示怎么添加一个合适的内存key并且填写与之对应的单位,返回值等信息在zabbix添加item项时。
例1:监控主机的总内存,剩余内存。
&&&&&& 通过图表和截图我们可以很方便的看出来相关的对应关系。截图中的key:vm.memory.size[total] 中的对应图表中的key&vm.memory.size[&mode&]而中括号中的mode这对应图表中的参数,这里为total,当然了大家也可以根据需要填写,比如监控内存以及使用的大小,这可以写成vm.memory.size[used] 。截图中的单位对应图表中的单位B,等等对应关系很容易看出来,这里就不多说了。然后大家按照quick章节中的实例为item绘图然后加入到screen里就可以了。
1.1&Zabbix对linux网卡的监控
Linux对网卡的监控的基本思路和监控其他linux项目没什么区别第一步添加linux主机,第二步为linux主机添加网卡相对应的item,任何在item的基础上绘制graph然后把graph集中添加到一张screen上方便集中展示。下面的图表为监控网卡流量用到的相关key。
net.if.in[if,&mode&]
Bytes,packets errors,dropped
Numeric (unsigned)
net.if.in[eth0,errors] &&&&&&&&&&& net.if.in[eth0]
net.if.out[if,&mode&]
Bytes,packets errors,dropped
Numeric (unsigned)
net.if.out[eth0,errors] &&&&&&&&&&& net.if.out[eth0]
net.if.total[if,&mode&]
Bytes,packets errors,dropped
Numeric (unsigned)
net.if.total[eth0,errors] &&&&&&&&&&& net.if.total[eth0]
这里需要主要添加item的时候数据存储类型store value要选择为Delta(speed per second)
例1:对linux主机eth0网卡进口流量的监控item
例2:对linux主机eth0网卡出口流量的监控item
为linux主机eth0网卡的进出网卡绘图。
1.1&Zabbix对cpu的监控
system.cpu.load[&cpu&,&mode&]
Cpu:all ,percpu
Avg1,avg5,avg15
Numeric (float)
system.cpu.load[,avg5]
system.cpu.num[&type&]
Online,max
Numeric (unsigned)
system.cpu.num
system.cpu.switches
Numeric (float)
system.cpu.switches
system.cpu.util[&cpu&,&type&,&mode&]
Cpu:all,number
Type:idle, nice, user,iowait,interrupt, softirq, steal
Mode:avg1,av5,avg15
Numeric (float)
system.cpu.util[0,user,avg5]
例1:linux主机cpu的负载item
linux主机cpu利用率绘图
1.1&Zabbix对磁盘的监控
首先我们添加主机,并且为主机添加一个item,然后在item上填写相关内容,其中key安装下面的格式来填写。
vfs.fs.size[fs,&mode&]
fs:文件系统
mode:total(默认)
free,used,pfree,pused
Numeric (unsigned)
vfs.fs.size[/tmp,free]
vfs.file.size[file]
Numeric (unsigned)
vfs.file.size[/var/log/syslog]
下图为监控/分区空间剩余大小的item截图。
为item绘图
1.1把监控的图像放入到一张screen中
创建screen:configure&screen&create screen,这里创建了一张名为test,2行2列的screen。
创建后入下图所示:
&&& 选择change后添加想要加入的graph,下图为添加内存图形(3.1中创建)到screen中,选中后双击保存按钮就行保存
依次双击change按钮添加上节 创建的4张graph图到名test的 screen中。
1.1&模板的创建
3.6.1创建模版
选择Configure&Templates&Create template
输入创建模板的名字和所在的组,然后保存即可。这时大家会发现多了一个名为test_linux但是里面的数据位空的
3.6.2向模版里导入数据
选择往模版里导入的主机的item,然后选择copy select to后双击go按钮。如下图所示
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
选择要导入的模版,然后双击copy按钮即可,同样方法可以把graph数据也导入模版里。
3.6.3 模版的使用
创建主机时选择模版按钮后点击add按钮选择关联的模版即可,最后选择save按钮进行保存。
3.6.4模版的导入导出
3.6.4.1模版的导出
选择Configure&Templates选择要导出的模版后,选择下方的Export selectd后双击go按钮,导出模版到想要保存的位置。
3.6.4.2模版的导入
选择Configure&Templates-import后双击浏览按钮后选择要导入的模版,已经导入的模版类型后双击,Import即可。

COMPONENTS 电子元器件
L6564T 10 pin transition-mode PFC controller for outdoor applications
The L6564T is a current-mode PFC controller operating in transition mode (TM)
and represents the compact version of the L6563S as it embeds the same driver,
reference and control stages in a very compact 10-pin SO package.
highly linear multiplier, along with a special correction circuit that reduces
crossover distortion of the mains current, allows wide-range-mains operation
with an extremely low THD even over a large load range.
The output
voltage is controlled by means of a voltage-mode error amplifier and an accurate
(1% @TJ = 25 °C) internal voltage reference. The loop stability is optimized by
the voltage feedforward function (1/V2 correction), which in this IC uses a
proprietary technique that also considerably improves line transient response in
case of both mains drops and surges (“bidirectional”).
In addition to
overvoltage protection able to control the output voltage during transient
conditions, the IC also provides protection against feedback loop failures or
erroneous settings. Other on-board protection functions allow brownout
conditions and boost inductor saturation to be safely handled.
totem-pole output stage, capable of a 600 mA source and 800 mA sink current, is
suitable for a high power MOSFET or IGBT drive. This, combined with the other
features and the possibility to operate with ST's proprietary fixed-off-time
control, makes the device an excellent solution for SMPS up to 400 W that
requires compliance with EN and JEITA-MITI standards
Guaranteed for extreme temperature range (outdoor)
Fast “bi-directional” input voltage feedforward (1/V2correction)
Accurate adjustable output overvoltage protection
Protection against feedback loop disconnection (latched shutdown)
Inductor saturation protection
AC brownout detection
Low (≤ 100 μA) startup current
6 mA max. operating bias current
1% (@ TJ= 25 °C) internal reference voltage
-600/+800 mA totem pole gate driver with active pull-down during UVLO
