</code></pre></div></div><h3id="-watch-namespace">-watch-namespace</h3><p>The <codeclass="language-plaintext highlighter-rouge notranslate">-watch-namespace</code> specifies the namespace to ensure that resource hardware topology examination only happens for the pods running in the specified namespace. Pods that are not running in the specified namespace are not considered during resource accounting. This is particularly useful for testing/debugging purpose. A "*" value would mean that all the pods would be considered during the accounting process.</p><p>Default: "*"</p><p>Example:</p><divclass="language-bash highlighter-rouge notranslate"><divclass="highlight"><preclass="highlight"><code>nfd-topology-updater <spanclass="nt">-watch-namespace</span><spanclass="o">=</span>rte
