<h5 id="maxsamples">-MaxSamples</h5>
<p>Specifies the number of samples to get from each counter. The default is 1 sample. To get samples continuously (no maximum sample size), use the Continuous parameter.<br />
To collect a very large data set, consider running a Get-DbaPfDataCollectorCounterSample command as a Windows PowerShell background job.<br></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>
