function Invoke-DbaPfRelog { <# .SYNOPSIS Pipable wrapper for the relog command which is available on modern Windows platforms. .DESCRIPTION Pipable 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 Appends output file instead of overwriting. This option does not apply to SQL format where the default is always to append. .PARAMETER AllowClobber Ovewrites the destination file 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 Displays the performance counters and time ranges of log files specified in the input file. .PARAMETER Multithread Parallelize the processing. This may speed up large batches or large files. .PARAMETER Raw Output the results of the DOS command instead of Get-ChildItem - does not multithread. .PARAMETER InputObject Allows input from Get-DbaPfDataCollector and Get-DbaPfDataCollectorSet .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 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/Invoke-DbaPfRelog .EXAMPLE Invoke-DbaPfRelog -Path C:\temp\perfmon.blg -Destination C:\temp\a\b\c Creats 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 Invoke-DbaPfRelog -Path C:\temp\perfmon.blg -Destination C:\temp\a\b\c -Raw Creats 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.
