作为一个大中企业的 DBA，要面对众多大中小多个数据库，除了及时发现异常问题，还要及时了解数据库表空间占用率，掌握空间增长速度过快情况，防止数据库空间不足。
本程序用 powershell 语言编写，通过配置文件所列清单，对数据库实例进行远程访问，获得除 undo 和临时表空间外其它表空间使用率，并按使用率进行由大到小的排序。
本程序将先检测 IP 地址和端口侦听是不是正常，如果数据库实例无法远程访问，见及时继续下一个数据库实例，而不会无限等待。
最主要的是将检查结果显示为 html 页面的一个表格内，使得检查结果直观，方便结果检查。
以下为程序源代码：
Add-PSSnapin VMware.VimAutomation.Core
function filestring-search($inputFile,$matchstring,$matchcount){
$tmpcontent = Get-Content $inputFile
for($i=0;$i -le $tmpcontent.length;i++)
{
if($tmpcontent[$i] -like ‘* 异常 *’){
$matchcount++
wite-host matchcount: $matchcount -background red
}
}
return
}
Function ConvertTo-AdvHTML
{ #
.SYNOPSIS
Advanced replacement of ConvertTo-HTML cmdlet
.DESCRIPTION
This function allows for vastly greater control over cells and rows
in a HTML table. It takes ConvertTo-HTML to a whole new level! You
can now specify what color a cell or row is (either dirctly or through
the use of CSS). You can add links, pictures and pictures AS links.
You can also specify a cell to be a bar graph where you control the
colors of the graph and text that can be included in the graph.
All color functions are through the use of imbedded text tags inside the
properties of the object you pass to this function. It is important to note
that this function does not do any processing for you, you must make sure all
control tags are already present in the object before passing it to the
function.
Here are the different tags available:
Syntax Comment
===================================================================================
[cell: color] optional text Designate the color of the cell. Must be
at the beginning of the string.
Example:
[cell:red]System Down
[row: color] Designate the color of the row. This control
can be anywhere, in any property of the object.
Example:
[row:orchid]
[cellclass: class] optional text
Designate the color, and other properties, of the
cell based on a class in your CSS. You must
have the class in your CSS (use the -CSS parameter).
Must be at the beginning of the string.
Example:
[cellclass:highlight]10mb
[rowclass: class] Designate the color, and other properties, of the
row based on a class in your CSS. You must
have the class in your CSS (use the -CSS parameter).
This control can be anywhere, in any property of the
object.
Example:
[rowclass:greyishbold]
[p_w_picpath: height;width;url] alternate text
Include an p_w_picpath in your cell. Put size of picture
in pixels and url seperated by semi-colons. Format
must be height;width;url. You can also include other
text in the cell, but the [p_w_picpath] tag must be at the
end of the tag (so the alternate text is last).
Example:
[p_w_picpath:100;200;http://www.sampleurl.com/samplep_w_picpath.jpg]Alt Text For Image
[link: url] link text Include a link in your cell. Other text is allowed in
the string, but the [link] tag must be at the end of the
string.
Example:
blah blah blah [link:www.thesurlyadmin.com]Cool PowerShell Link
[linkpic: height;width;url to pic] url for link
This tag uses a picture which you can click on and go to the
specified link. You must specify the size of the picture and
url where it is located, this information is seperated by semi-
colons. Other text is allowed in the string, but the [link] tag
must be at the end of the string.
Example:
[linkpic:100;200;http://www.sampleurl.com/samplep_w_picpath.jpg]www.thesurlyadmin.com
[bar: percent;bar color;remainder color] optional text
Bar graph makes a simple colored bar graph within the cell. The
length of the bar is controlled using percent . You can
designate the color of the bar, and the color of the remainder
section. Due to the mysteries of HTML, you must designate a
width for the column with the [bar] tag using the HeadWidth parameter.
So if you had a percentage of 95, say 95% used disk you
would want to highlight the remainder for your report:
Example:
[bar:95;dark green;red]5% free
What if you were at 30% of a sales goal with only 2 weeks left in
the quarter, you would want to highlight that you have a problem.
Example:
[bar:30;darkred;red]30% of goal
.PARAMETER InputObject
The object you want converted to an HTML table
.PARAMETER HeadWidth
You can specify the width of a cell. Cell widths are in pixels
and are passed to the parameter in array format. Each element
in the array corresponds to the column in your table, any element
that is set to 0 will designate the column with be dynamic. If you had
four elements in your InputObject and wanted to make the 4th a fixed
width–this is required for using the [bar] tag–of 600 pixels:
-HeadWidth 0,0,0,600
.PARAMETER CSS
Designate custom CSS for your HTML
.PARAMETER Title
Specifies a title for the HTML file, that is, the text that appears between the TITLE tags.
.PARAMETER PreContent
Specifies text to add before the opening TABLE tag. By default, there is no text in that position.
.PARAMETER PostContent
Specifies text to add after the closing /TABLE tag. By default, there is no text in that position.
.PARAMETER Body
Specifies the text to add after the opening BODY tag. By default, there is no text in that position.
.PARAMETER Fragment
Generates only an HTML table. The HTML, HEAD, TITLE, and BODY tags are omitted.
.INPUTS
System.Management.Automation.PSObject
You can pipe any .NET object to ConvertTo-AdvHtml.
.OUTPUTS
System.String
ConvertTo-AdvHtml returns series of strings that comprise valid HTML.
.EXAMPLE
$Data = @”
Server,Description,Status,Disk
[row:orchid]Server1,Hello1,[cellclass:up]Up,”[bar:45;Purple;Orchid]55% Free”
Server2,Hello2,[cell:green]Up,”[bar:65;DarkGreen;Green]65% Used”
Server3,Goodbye3,[cell:red]Down,”[bar:95;DarkGreen;DarkRed]5% Free”
server4,This is quite a cool test,[cell:green]Up,”[p_w_picpath:150;650;https://cache.yisu.com/upload/information/20200310/37/83917.jpg]Test Images”
server5,SurlyAdmin,[cell:red]Down,”[link:http://thesurlyadmin.com]The Surly Admin”
server6,MoreSurlyAdmin,[cell:purple]Updating,”[linkpic:150;650;https://cache.yisu.com/upload/information/20200310/37/83917.jpg]http://thesurlyadmin.com”
“@
$Data = $Data | ConvertFrom-Csv
$HTML = $Data | ConvertTo-AdvHTML -HeadWidth 0,0,0,600 -PreContent ” p h2 This might be the best report EVER /h2 /p br ” -PostContent ” br Done! $(Get-Date)” -Title “Cool Test!”
This is some sample code where I try to put every possibile tag and use into a single set
of data. $Data is the PSObject 4 columns. Default CSS is used, so the [cellclass:up] tag
will not work but I left it there so you can see how to use it.
