When it first opens, the Network Monitor does not show request information. The just opened tool looks like this:</p><img alt="../../_images/network_monitor_new.png" class="border" src="../../_images/network_monitor_new.png"> <p>Either action causes the Network Monitor to begin monitoring network activity. Once the tool is monitoring network requests, the display looks like this:</p><img alt="../../_images/network_monitor.png" class="border" src="../../_images/network_monitor.png"> <p>When it is actively monitoring activity, the Network Monitor records network requests any time the Toolbox is open, even if the Network Monitor itself is not selected. This means you can start debugging a page in, for example, the Web Console, then switch to the Network Monitor to see network activity without having to reload the page.</p> </section> <section id="ui-overview"> <h2>UI overview<a class="headerlink" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB#ui-overview" title="Link to this heading">¶</a></h2> <p>The UI is divided into four main pieces:</p> <ul class="simple"> <li><p>The main screen contains the <a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/toolbar/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">toolbar</span></a>, the <a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/request_list/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">network request list</span></a>, and the <a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/request_details/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">network request details pane</span></a>:</p></li> </ul><img alt="../../_images/network_monitor_closeup.png" class="border" src="../../_images/network_monitor_closeup.png"> <ul class="simple"> <li><p>The <span class="xref std std-doc">performance analysis</span> view is a separate screen:</p></li> </ul><img alt="../../_images/network_performance.png" class="border" src="../../_images/network_performance.png"> </section> <section id="working-with-the-network-monitor"> <h2>Working with the network monitor<a class="headerlink" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB#working-with-the-network-monitor" title="Link to this heading">¶</a></h2> <p>The following articles cover different aspects of using the network monitor:</p> <ul class="simple"> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/toolbar/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Toolbar</span></a></p></li> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/request_list/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Network request list</span></a></p></li> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/request_details/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Network request details</span></a></p></li> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/performance_analysis/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Network traffic recording</span></a></p></li> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/throttling/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Throttling</span></a></p></li> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/inspecting_web_sockets/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Inspecting web sockets</span></a></p></li> <li><p><a class="reference internal" href="https://firefox--source--docs-mozilla-org.translate.goog/devtools-user/network_monitor/inspecting_server-sent_events/index.html?_x_tr_sl=pl&_x_tr_tl=tr&_x_tr_hl=en-GB"><span class="doc">Inspecting server-sent events</span></a></p></li> </ul> </section> </section> </div> </div> <footer> <hr> <div role="contentinfo"> <p></p> </div> Built with <a href="https://translate.google.com/website?sl=pl&tl=tr&hl=en-GB&u=https://www.sphinx-doc.org/">Sphinx</a> using a <a href="https://translate.google.com/website?sl=pl&tl=tr&hl=en-GB&u=https://github.com/readthedocs/sphinx_rtd_theme">theme</a> provided by <a href="https://translate.google.com/website?sl=pl&tl=tr&hl=en-GB&u=https://readthedocs.org">Read the Docs</a>. </footer> </div> </div> </section> </div> <script> jQuery(function () { SphinxRtdTheme.Navigation.enable(true); }); </script> <script>function gtElInit() {var lib = new google.translate.TranslateService();lib.translatePage('pl', 'tr', function () {});}</script> <script src="https://translate.google.com/translate_a/element.js?cb=gtElInit&hl=en-GB&client=wt" type="text/javascript"></script> </body> </html>
