Pipeline-compatible wrapper for the relog command which is available on modern Windows platforms.
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.

PS C:\> Invoke-DbaPfRelog -Path C:\temp\perfmon.blg
Creates C:\temp\perfmon.tsv from C:\temp\perfmon.blg.
PS C:\> 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.
PS C:\> 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.

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.
PS C:\> Invoke-DbaPfRelog -Path 'C:\temp\perflog with spaces.blg' -Destination C:\temp\a\b\c -Type csv -BeginTime ((Get-Date).AddDays(-30)) -EndTime ((Get-Date).AddDays(-1))
Creates the temp, a, and b directories if needed, then generates c.csv (comma separated) from C:\temp\perflog with spaces.blg', starts 30 days ago and ends one day ago.
PS C:\> $servers | Get-DbaPfDataCollectorSet | Get-DbaPfDataCollector | Invoke-DbaPfRelog -Multithread -AllowClobber
Relogs latest data files from all collectors within the servers listed in $servers.
PS C:\> Get-DbaPfDataCollector -Collector DataCollector01 | Invoke-DbaPfRelog -AllowClobber -AllTime
Relogs all the log files from the DataCollector01 on the local computer and allows overwrite.
Specifies the pathname of an existing performance counter log or performance counter path. You can specify multiple input files.
| Alias | FullName |
| Required | False |
| Pipeline | true (ByPropertyName) |
| Default Value |
Specifies the pathname of the output file or SQL database where the counters will be written. Defaults to the same directory as the source.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
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).

| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | tsv |
| Accepted Values | tsv,csv,bin,sql |
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.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, the destination file will be overwritten if it exists.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Specifies the performance counter path to log.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
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.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies sample intervals in "n" records. Includes every nth data point in the relog file. Default is every data point.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | 0 |
This is is Get-Date object and we format it for you.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies end time for copying last record from the input file. This is is Get-Date object and we format it for you.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
Specifies the pathname of the settings file that contains command-line parameters.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value |
If this switch is enabled, the performance counters and time ranges of log files specified in the input file will be displayed.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
Accepts the output of Get-DbaPfDataCollector and Get-DbaPfDataCollectorSet as input via the pipeline.
| Alias | |
| Required | False |
| Pipeline | true (ByValue) |
| Default Value |
If this switch is enabled, processing will be done in parallel. This may speed up large batches or large files.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled and a datacollector or datacollectorset is passed in via the pipeline, collects all logs, not just the latest.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
If this switch is enabled, the results of the DOS command instead of Get-ChildItem will be displayed. This does not run in parallel.
| Alias | |
| Required | False |
| Pipeline | false |
| Default Value | False |
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.

| Required | False |
| Pipeline | false |
