#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Invoke-DbaPfRelog { <# .SYNOPSIS Pipeline-compatible wrapper for the relog command which is available on modern Windows platforms. .DESCRIPTION Pipeline-compatible wrapper for the relog command. Relog is useful for converting Windows Perfmon. Extracts performance counters from performance counter logs into other formats, such as text-TSV (for tab-delimited text), text-CSV (for comma-delimited text), binary-BIN, or SQL. relog "C:\PerfLogs\Admin\System Correlation\WORKSTATIONX_20180112-000001\DataCollector01.blg" -o C:\temp\foo.csv -f tsv If you find any input hangs, please send us the output so we can accommodate for it then use -Raw for an immediate solution. .PARAMETER Path Specifies the pathname of an existing performance counter log or performance counter path. You can specify multiple input files. .PARAMETER Destination Specifies the pathname of the output file or SQL database where the counters will be written. Defaults to the same directory as the source. .PARAMETER Type The output format. Defaults to tsv. Options include tsv, csv, bin, and sql. For a SQL database, the output file specifies the DSN!counter_log. You can specify the database location by using the ODBC manager to configure the DSN (Database System Name). For more information, read here: https://technet.microsoft.com/en-us/library/bb490958.aspx .PARAMETER Append If this switch is enabled, output will be appended to the specified file instead of overwriting. This option does not apply to SQL format where the default is always to append. .PARAMETER AllowClobber If this switch is enabled, the destination file will be overwritten if it exists. .PARAMETER PerformanceCounter Specifies the performance counter path to log. .PARAMETER PerformanceCounterPath Specifies the pathname of the text file that lists the performance counters to be included in a relog file. Use this option to list counter paths in an input file, one per line. Default setting is all counters in the original log file are relogged. .PARAMETER Interval Specifies sample intervals in "n" records. Includes every nth data point in the relog file. Default is every data point. .PARAMETER BeginTime This is is Get-Date object and we format it for you. .PARAMETER EndTime Specifies end time for copying last record from the input file. This is is Get-Date object and we format it for you. .PARAMETER ConfigPath Specifies the pathname of the settings file that contains command-line parameters. .PARAMETER Summary If this switch is enabled, the performance counters and time ranges of log files specified in the input file will be displayed. .PARAMETER Multithread If this switch is enabled, processing will be done in parallel. This may speed up large batches or large files. .PARAMETER AllTime If this switch is enabled and a datacollector or datacollectorset is passed in via the pipeline, collects all logs, not just the latest. .PARAMETER Raw If this switch is enabled, the results of the DOS command instead of Get-ChildItem will be displayed. This does not run in parallel. .PARAMETER InputObject Accepts the output of Get-DbaPfDataCollector and Get-DbaPfDataCollectorSet as input via the pipeline. .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: Performance, DataCollector, PerfCounter, Relog 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-DbaPfRelog .EXAMPLE Invoke-DbaPfRelog -Path C:\temp\perfmon.blg Creates C:\temp\perfmon.tsv from C:\temp\perfmon.blg. .EXAMPLE Invoke-DbaPfRelog -Path C:\temp\perfmon.blg -Destination C:\temp\a\b\c Creates the temp, a, and b directories if needed, then generates c.tsv (tab separated) from C:\temp\perfmon.blg. Returns the newly created file as a file object. .EXAMPLE Get-DbaPfDataCollectorSet -ComputerName sql2016 | Get-DbaPfDataCollector | Invoke-DbaPfRelog -Destination C:\temp\perf Creates C:\temp\perf if needed, then generates computername-datacollectorname.tsv (tab separated) from the latest logs of all data collector sets on sql2016. This destination format was chosen to avoid naming conflicts with piped input. .EXAMPLE Invoke-DbaPfRelog -Path C:\temp\perfmon.blg -Destination C:\temp\a\b\c -Raw Creates the temp, a, and b directories if needed, then generates c.tsv (tab separated) from C:\temp\perfmon.blg then outputs the raw results of the relog command.
