</thead>
<tbody>
<tr><td data-label="Server Name">PRD-MSSQL01C</td><td data-label="Trace Flag">1222</td><td data-label="Status">1</td><td data-label="Global">1</td><td data-label="Session">0</td></tr>
<tr><td data-label="Server Name">PRD-MSSQL01C</td><td data-label="Trace Flag">1224</td><td data-label="Status">1</td><td data-label="Global">1</td><td data-label="Session">0</td></tr>
