function Install-DbaWhoIsActive { <# .SYNOPSIS Automatically installs or updates sp_WhoisActive by Adam Machanic. .DESCRIPTION This command downloads, extracts and installs sp_WhoisActive with Adam's permission. To read more about sp_WhoisActive, please visit http://whoisactive.com and http://sqlblog.com/blogs/adam_machanic/archive/tags/who+is+active/default.aspx Please consider donating to Adam if you find this stored procedure helpful: http://tinyurl.com/WhoIsActiveDonate Note that you will be prompted a bunch of times to confirm an action. .PARAMETER SqlInstance The SQL Server instance. Server version must be SQL Server version 2005 or higher. .PARAMETER SqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SqlCredential parameter. Windows Authentication will be used if SqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Database The database to install sp_WhoisActive into. This parameter is mandatory when executing this command unattended. .PARAMETER LocalFile Specifies the path to a local file to install sp_WhoisActive from. This can be either the zipfile as distributed by the website or the expanded SQL script. If this parameter is not specified, the latest version will be downloaded and installed from https://whoisactive.com/ .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER Force If this switch is enabled, the sp_WhoisActive will be downloaded from the internet even if previously cached. .EXAMPLE Install-DbaWhoIsActive -SqlInstance sqlserver2014a -Database master Downloads sp_WhoisActive from the internet and installs to sqlserver2014a's master database. Connects to SQL Server using Windows Authentication. .EXAMPLE Install-DbaWhoIsActive -SqlInstance sqlserver2014a -SqlCredential $cred Pops up a dialog box asking which database on sqlserver2014a you want to install the procedure into. Connects to SQL Server using SQL Authentication. .EXAMPLE Install-DbaWhoIsActive -SqlInstance sqlserver2014a -Database master -LocalFile c:\SQLAdmin\whoisactive_install.sql Installs sp_WhoisActive to sqlserver2014a's master database from the local file whoisactive_install.sql .EXAMPLE $instances = Get-DbaRegisteredServer sqlserver Install-DbaWhoIsActive -SqlInstance $instances -Database master .NOTES Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Install-DbaWhoIsActive #> [CmdletBinding(SupportsShouldProcess)] param ( [parameter(Mandatory = $true, ValueFromPipeline = $true, Position = 0)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PsCredential]$SqlCredential, [parameter(Mandatory=$false)] [ValidateScript({Test-Path -Path $_ -PathType Leaf})] [string]$LocalFile, [object]$Database, [switch][Alias('Silent')]$EnableException, [switch]$Force ) begin { $DbatoolsData = Get-DbaConfigValue -Name "Path.DbatoolsData" $temp = ([System.IO.Path]::GetTempPath()).TrimEnd("\") $zipfile = "$temp\spwhoisactive.zip" if ($LocalFile -eq $null -or $LocalFile.Length -eq 0) { $baseUrl = "http://whoisactive.com/downloads" $latest = ((Invoke-WebRequest -UseBasicParsing -uri http://whoisactive.com/downloads).Links | where-object {$PSItem.href -match "who_is_active"} | Select-Object href -First 1).href $LocalCachedCopy = Join-Path -Path $DbatoolsData -ChildPath $latest; if ((Test-Path -Path $LocalCachedCopy -PathType Leaf) -and (-not $Force)) { Write-Message -Level Verbose -Message "Locally-cached copy exists, skipping download." if ($PSCmdlet.ShouldProcess($env:computername, "Copying sp_WhoisActive from local cache for installation")) { Copy-Item -Path $LocalCachedCopy -Destination $zipfile; } } else { if ($PSCmdlet.ShouldProcess($env:computername, "Downloading sp_WhoisActive")) { try { Write-Message -Level Verbose -Message "Downloading sp_WhoisActive zip file, unzipping and installing." $url = $baseUrl + "/" + $latest try { Invoke-WebRequest $url -OutFile $zipfile -ErrorAction Stop -UseBasicParsing Copy-Item -Path $zipfile -Destination $LocalCachedCopy } catch { #try with default proxy and usersettings (New-Object System.Net.WebClient).Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials Invoke-WebRequest $url -OutFile $zipfile -ErrorAction Stop -UseBasicParsing } } catch { Stop-Function -Message "Couldn't download sp_WhoisActive.
