如何查看服务器当前的负载信息

如何查看服务器当前的负载信息,第1张

做压力测试的时候想看看linux服务器当前负载如何,性能怎样,可以使用下面这些命令

uptime

显示当前用户数,以及最近1

分钟内、5分钟内、15

分钟内系统的平均负载

cat

/proc/loadavg

用于显示系统1秒钟平均负载、5秒钟平均负载、15秒钟平均负载、总作业数、正在运行的作业总数

cat

/proc/stat

这个显示的内容较多,具体的就不一一列举了,需要的朋友可以自己查阅相关资料

The module - psutil is what you want.

easy_install psutil

or

pip install psutil

1、在远程server里搭建一个http服务,并支持某种服务端语言(如.net或php之类)

2、用服务端语言获取到服务器的磁盘信息,把结果输出

3、在本地用JS写一段AJAX脚本,远程请求服务端写好的程序,得到结果,并展示给用户

<html>

<head>

<title>提取硬盘序列号</title>

<script>

function disk() {//硬盘序列号 信息

var locator = new ActiveXObject ("WbemScripting.SWbemLocator")

var service = locator.ConnectServer(".")

var properties = service.ExecQuery("SELECT * FROM Win32_DiskDrive")

var e = new Enumerator (properties)

document.write("<table border=1>")

for (!e.atEnd()e.moveNext ())

{

var p = e.item ()

document.write("<tr>")

document.write("<td>" + p.signature + "</td>")

document.write("</tr>")

}

document.write("</table>")

}

</script>

</head>

<body>

<input type="button" value="硬盘序列号" onclick="disk()">

</body>

</html>

在这上找的代码:

对于写过ASP或.net 的人来说,通过asp或.net 语言来获得客户端的硬件信息是很熟悉的.但如何通过javascript这种客户端脚本来获得客户端的信息呢?请看以下实例:

<head>

<title>javascript获得客户端硬件信息-www.web2bar.cn/</title>

<script id=clientEventHandlersJS language=javascript>

function Button2_onclick() {//CPU 信息

var locator = new ActiveXObject ("WbemScripting.SWbemLocator")

var service = locator.ConnectServer(".")

var properties = service.ExecQuery("SELECT * FROM Win32_Processor")

var e = new Enumerator (properties)

document.write("<table border=1>")

for (!e.atEnd()e.moveNext ())

{

var p = e.item ()

document.write("<tr>")

document.write("<td>" + p.Caption + "</td>")

document.write("<td>" + p.DeviceID + "</td>")

document.write("<td>" + p.Name + "</td>")

document.write("<td>" + p.CpuStatus + "</td>")

document.write("<td>" + p.Availability + "</td>")

document.write("<td>" + p.Level + "</td>")

document.write("<td>" + p.ProcessorID + "</td>")

document.write("<td>" + p.SystemName + "</td>")

document.write("<td>" + p.ProcessorType + "</td>")

document.write("</tr>")

}

document.write("</table>")

}

function Button1_onclick() {//软盘信息

var locator = new ActiveXObject ("WbemScripting.SWbemLocator")

var service = locator.ConnectServer(".")

var properties = service.ExecQuery("SELECT * FROM Win32_FloppyDrive")

var e = new Enumerator (properties)

document.write("<table border=1>")

for (!e.atEnd()e.moveNext ())

{

var p = e.item ()

document.write("<tr>")

document.write("<td>" + p.Description + "</td>")

document.write("<td>" + p.DeviceID + "</td>")

document.write("<td>" + p.Status + "</td>")

document.write("<td>" + p.Manufacuturer + "</td>")

document.write("</tr>")

}

document.write("</table>")

}

function Button1_onclick() {//CD-ROM 信息

var locator = new ActiveXObject ("WbemScripting.SWbemLocator")

var service = locator.ConnectServer(".")

var properties = service.ExecQuery("SELECT * FROM Win32_CDROMDrive")

var e = new Enumerator (properties)

document.write("<table border=1>")

for (!e.atEnd()e.moveNext ())

{

var p = e.item ()

document.write("<tr>")

document.write("<td>" + p.Caption + "</td>")

document.write("<td>" + p.Description + "</td>")

document.write("<td>" + p.Drive + "</td>")

document.write("<td>" + p.Status + "</td>")

document.write("<td>" + p.MediaLoaded + "</td>")

document.write("</tr>")

}

document.write("</table>")

}

function Button1_onclick() {//键盘信息

var locator = new ActiveXObject ("WbemScripting.SWbemLocator")

var service = locator.ConnectServer(".")

var properties = service.ExecQuery("SELECT * FROM Win32_Keyboard")

var e = new Enumerator (properties)

document.write("<table border=1>")

for (!e.atEnd()e.moveNext ())

{

var p = e.item ()

document.write("<tr>")

document.write("<td>" + p.Description + "</td>")

document.write("<td>" + p.Name + "</td>")

document.write("<td>" + p.Status + "</td>")

document.write("</tr>")

}

document.write("</table>")

}

function Button1_onclick() {//主板信息

var locator = new ActiveXObject ("WbemScripting.SWbemLocator")

var service = locator.ConnectServer(".")

var properties = service.ExecQuery("SELECT * FROM Win32_BaseBoard")

var e = new Enumerator (properties)

document.write("<table border=1>")

for (!e.atEnd()e.moveNext ())

{

var p = e.item ()

document.write("<tr>")

document.write("<td>" + p.HostingBoard + "</td>")

document.write("<td>" + p.Manufacturer + "</td>")

document.write("<td>" + p.PoweredOn + "</td>")

document.write("<td>" + p.Product + "</td>")

document.write("<td>" + p.SerialNumber + "</td>")

document.write("<td>" + p.Version + "</td>")

document.write("</tr>")

}

document.write("</table>")

}

//-->

</script>

</head>

<body>

<INPUT id="Button1" type="button" value="Button"

name="Button1" language=javascript onclick="return Button1_onclick()">

</body>

</html>

使用javascript方式获得客户端的信息主要的优点是,不需求服务器资源.不需求刷新网页.直接在客户端执行脚本获得显示.

在这上找到了硬盘序列号的参数:

\'获得硬盘序列号

Dim cmicWmi As New System.Management.ManagementObjectSearcher(\"SELECT * FROM Win32_DiskDrive\")

Dim Uint32 As UInt32

For Each cmicWmiObj As ManagementObject In cmicWmi.Get

Uint32 = cmicWmiObj(\"signature\")

Next

TextBox1.Text = Uint32.ToString
