<h2 id="synopsis">Synopsis</h2>
<p>Pipeline-compatible wrapper for the relog command which is available on modern Windows platforms.</p>
<h2 id="description">Description</h2>
<p>Pipeline-compatible wrapper for the relog command. Relog is useful for converting Windows Perfmon.</p>
<p>Extracts performance counters from performance counter logs into other formats,<br />
such as text-TSV (for tab-delimited text), text-CSV (for comma-delimited text), binary-BIN, or SQL.</p>
<p><code>relog &quot;C:\PerfLogs\Admin\System Correlation\WORKSTATIONX_20180112-000001\DataCollector01.blg&quot; -o C:\temp\foo.csv -f tsv</code></p>
<p>If you find any input hangs, please send us the output so we can accommodate for it then use -Raw for an immediate solution.</p>

<h5 id="enableexception">-EnableException</h5>
<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
