<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br /><br /> I am trying to find
moreinformation about the PgAdmin 4 Tabbed Browser. In the page, we have a couple of graphs and the documentation
said:<br/><br /><p>The <em>Dashboard</em> tab provides a graphical analysis of the usage statistics for the selected
serveror database:<ul class="simple"><li>The <em>Server sessions</em> or <em>Database sessions</em> graph displays the
interactionswith the managed server or database.<li>The <em>Transactions per second</em> graph displays the commits,
rollbacks,and total transactions per second that are taking place on the managed server or database.<li>The <em>Tuples
In</em>graph displays the number of tuples inserted, updated, and deleted into the managed server or database.<li>The
<em>Tuplesout</em> graph displays the number of tuples fetched and returned into the managed server or database.<li>The
<em>BlockI/O</em> graph displays the number of transactions processed by the managed server or database.</ul> Is there
anyother documentation explain what those graphs means? More specifically, the last graph "Block I/O" does not make a
wholelot of sense to me... What does Block I/O has to do with the number of transactions processed?<br /><br /> Ed.<br
