Adding the network stack and the HTTPD package to anyconfiguration will enable the monitor by default. It may be disabledby disabling the <TTCLASS="LITERAL">CYGPKG_HTTPD_MONITOR</TT> option.</P><P>The monitor is intended to be simple and self-explanatory in use. Itconsists of four main pages. The thread monitor page presents a tableof all current threads showing such things as id, state, priority,name and stack dimensions. Clicking on the thread ID will link to athread edit page where the thread's state and priority may bemanipulated. The interrupt monitor just shows a table of the currentinterrupts and indicates which are active. The memory monitor shows a256 byte page of memory, with controls to change the base address anddisplay element size. The network monitor page showsinformation extracted from the active network interfaces andprotocols. Finally, if kernel instrumentation is enabled, theinstrumentation page provides some controls over the instrumentationmechanism, and displays the instrumentation buffer.</P></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLESUMMARY="Footer navigation table"WIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="net-httpd-html.html"ACCESSKEY="P">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="ecos-ref.html"ACCESSKEY="H">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="net-ftpclient.html"ACCESSKEY="N">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">Support Functions and Macros</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="net-httpd-chapter.html"ACCESSKEY="U">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">FTP Client for eCos TCP/IP Stack</TD></TR></TABLE></DIV></BODY></HTML>⌨️ 快捷键说明
