function Invoke-DbaXeReplay { <# .SYNOPSIS This command replays events from Read-DbaXEFile on one or more target servers .DESCRIPTION This command replays events from Read-DbaXEFile. It is simplistic in its approach. - Writes all queries to a temp sql file - Executes temp file using . $sqlcmd so that batches are executed properly - Deletes temp file .PARAMETER SqlInstance Target SQL Server(s) .PARAMETER SqlCredential Used to provide alternative credentials. .PARAMETER Database The initial starting database. .PARAMETER Event Each Response can be limited to processing specific events, while ignoring all the other ones. When this attribute is omitted, all events are processed. .PARAMETER Raw By dafault, the results of . $sqlcmd are collected, cleaned up and displayed. If you'd like to see all results immeidately, use Raw. .PARAMETER InputObject Accepts the object output of Read-DbaXESession. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: ExtendedEvent, XE, XEvent Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Invoke-DbaXEReplay .EXAMPLE PS C:\> Read-DbaXEFile -Path C:\temp\sample.xel | Invoke-DbaXeReplay -SqlInstance sql2017 Runs all batch_text for sql_batch_completed against tempdb on sql2017. .EXAMPLE PS C:\> Read-DbaXEFile -Path C:\temp\sample.xel | Invoke-DbaXeReplay -SqlInstance sql2017 -Database planning -Event sql_batch_completed Sets the *initial* database to planning then runs only sql_batch_completed against sql2017. .EXAMPLE PS C:\> Read-DbaXEFile -Path C:\temp\sample.xel | Invoke-DbaXeReplay -SqlInstance sql2017, sql2016 Runs all batch_text for sql_batch_completed against tempdb on sql2017 and sql2016. #> [Cmdletbinding()] [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseOutputTypeCorrectly", "", Justification = "PSSA Rule Ignored by BOH")] param ( [Parameter(Mandatory)] [DbaInstance[]]$SqlInstance, [PsCredential]$SqlCredential, [string[]]$Database, [string[]]$Event = @('sql_batch_completed', 'rcp_completed'), [Parameter(Mandatory, ValueFromPipeline)] [object]$InputObject, [switch]$Raw, [switch]$EnableException ) begin { #Variable marked as unused by PSScriptAnalyzer #$querycolumns = 'statement', 'batch_text' $timestamp = (Get-Date -Format yyyyMMddHHmm) $temp = ([System.IO.Path]::GetTempPath()).TrimEnd("\") $filename = "$temp\dbatools-replay-$timestamp.sql" Set-Content $filename -Value $null $sqlcmd = "$script:PSModuleRoot\bin\sqlcmd\sqlcmd.exe" } process { if (Test-FunctionInterrupt) { return } if ($InputObject.Name -notin $Event) { continue } if ($InputObject.statement) { if ($InputObject.statement -notmatch "ALTER EVENT SESSION") { Add-Content -Path $filename -Value $InputObject.statement Add-Content -Path $filename -Value "GO" } } else { if ($InputObject.batch_text -notmatch "ALTER EVENT SESSION") { Add-Content -Path $filename -Value $InputObject.batch_text Add-Content -Path $filename -Value "GO" } } } end { if (Test-FunctionInterrupt) { return } foreach ($instance in $SqlInstance) { try { $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failure" -ErrorRecord $_ -Target $instance -Continue } if ($Raw) { Write-Message -Message "Invoking XEReplay against $instance running on $($server.name) with raw output" -Level Verbose if (Test-Bound -ParameterName SqlCredential) { . $sqlcmd -S $instance -i $filename -U $SqlCredential.Username -P $SqlCredential.GetNetworkCredential().Password continue } else { . $sqlcmd -S $instance -i $filename continue } } Write-Message -Message "Invoking XEReplay against $instance running on $($server.name)" -Level Verbose if (Test-Bound -ParameterName SqlCredential) { $output = . $sqlcmd -S $instance -i $filename -U $SqlCredential.Username -P $SqlCredential.GetNetworkCredential().Password } else { $output = . $sqlcmd -S $instance -i $filename } foreach ($line in $output) { $newline = $line.Trim() if ($newline -and $newline -notmatch "------------------------------------------------------------------------------------") { "$newline" } } } Remove-Item -Path $filename -ErrorAction Ignore } } |
