<p>If available, Cockpit uses the
<a class="ulink" href="http://www.pcp.io/" target="_top">Performance Co-Pilot</a> framework to
gather metrics data about the system. This data is used to display graphs.
Cockpit can use the PCP logging feature to display archived data about the
system from a different point in time. If PCP is not available, then Cockpit
gathers the metrics data itself, but archival features are not available.</p>
<p>To see similar metrics data from the command line, you can use tools like
<a class="ulink" href="http://www.pcp.io/books/PCP_UAG/html/LE38515-PARENT.html#LE91266-PARENT" target="_top"><code class="code">pmstat</code></a>
or <a class="ulink" href="http://www.pcp.io/books/PCP_UAG/html/LE60452-PARENT.html" target="_top"><code class="code">pminfo</code></a>:</p>
