                    This page allows you to browse all connections currently connected to the broker, including client, cluster
                    and bridge connections. These can be narrowed down by specifying a filter and also sorted using the sort
                    function in the toolbar. To execute a query click on the <span class="fa fa-search"></span> button.
                </p>
                <p>
                    Connections can be closed by using the <code>close</code> button under the <code>Actions</code> column and you can
                    navigate to the connections sessions open by clicking on the <code>Session Count</code> field.
                  </p>
                  <p>
                    Note that each page is loaded in from the broker when navigating to a new page or when a query is executed.
