<h2 id="synopsis">Synopsis</h2>
<p>Reads the live Transaction log from specified SQL Server Database</p>
<h2 id="description">Description</h2>
<p>Using the fn_dblog function, the live transaction log is read and returned as a PowerShell object</p>
<p>This function returns the whole of the log. The information is presented in the format that the logging subsystem uses.</p>
<p>A soft limit of 0.5GB of log as been implemented. This is based on testing. This limit can be overridden<br />
at the users request, but please be aware that this may have an impact on your target databases and on the<br />
system running this function</p>
<h2 id="syntax">Syntax</h2>
<pre><code>Read-DbaTransactionLog
    [-SqlInstance] &lt;DbaInstanceParameter&gt;
    [[-SqlCredential] &lt;PSCredential&gt;]
    [-Database] &lt;Object&gt;
    [-IgnoreLimit]
    [[-RowLimit] &lt;Int32&gt;]
    [-EnableException]
    [&lt;CommonParameters&gt;]

</code></pre>
<p> </p>
<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; $Log = Read-DbaTransactionLog -SqlInstance sql2016 -Database MyDatabase
</code></pre>
<p>Will read the contents of the transaction log of MyDatabase on SQL Server Instance sql2016 into the local PowerShell object $Log<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; $Log = Read-DbaTransactionLog -SqlInstance sql2016 -Database MyDatabase -IgnoreLimit
</code></pre>
<p>Will read the contents of the transaction log of MyDatabase on SQL Server Instance sql2016 into the local PowerShell object $Log, ignoring the recommendation of not returning more that 0.5GB of log<br></p>

<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>
