Request for Support in Extracting and Mirroring Data Between Sites

I’m developing an internal monitoring site for gateways (GW), but I’m facing some challenges. Some GWs display call data using the following HTML structure:

<th class="route">Totais</th>

<th class="calling"></th>

<th class="conn"></th>

<th class="talking">20</th>

<th class="tot">20</th>

In my system, I extract data from the <th class="tot"> field.

However, other GWs load data dynamically through a variable in JavaScript, making direct access difficult. Here’s the code snippet from these GWs:

<script language="javascript">
  var dados = 'dados.html';
  $(tabela).load(dados);
  setInterval(function() {
    $(tabela).load(dados);
  }, 2000);
</script>

Is there any way to access the data or query it directly from the source?

I appreciate your help and look forward to any solutions or recommendations you may have.

I integrated AJAX to fetch total calls from each gateway’s HTML and store them in a global variable. I expected the data to load dynamically every 5 seconds and display the correct call totals in the corresponding boxes on the webpage.
