- <title>DESCRIPTION</title>
- <para>
- <command>b10-stats-httpd</command> is a standalone HTTP server. It is
- intended for HTTP/XML interface for statistics module. This server
- process runs as a process separated from the process of the BIND 10 Stats
- daemon (<command>b10-stats</command>). The server is initially executed
- by the BIND 10 boss process (<command>bind10</command>) and eventually
- exited by it. The server is intended to be server requests by HTTP
- clients like web browsers and third-party modules. When the server is
- asked, it requests BIND 10 statistics data or its schema from
- <command>b10-stats</command>, and it sends the data back in Python
- dictionary format and the server converts it into XML format. The server
- sends it to the HTTP client. The server can send three types of document,
- which are XML (Extensible Markup Language), XSD (XML Schema definition)
- and XSL (Extensible Stylesheet Language). The XML document is the
- statistics data of BIND 10, The XSD document is the data schema of it,
- and The XSL document is the style sheet to be showed for the web
- browsers. There is different URL for each document. But please note that
- you would be redirected to the URL of XML document if you request the URL
- of the root document. For example, you would be redirected to
- http://127.0.0.1:8000/bind10/statistics/xml if you request
- http://127.0.0.1:8000/. Please see the manual and the spec file
- of <command>b10-stats</command> for more details about the items of BIND
- 10 statistics. The server uses CC session in communication
- with <command>b10-stats</command>. CC session is provided
- by <command>b10-msgq</command> which is started
- by <command>bind10</command> in advance. The server is implemented by
- HTTP-server libraries included in Python 3. The server obtains the
- configuration from the config manager (<command>b10-cfgmgr</command>) in
- runtime. Please see below for more details about this spec file and
- configuration of the server.

- <para>
- The configurable setting in
- <filename>stats-httpd.spec</filename> is:
- </para>
- <variablelist>
- <varlistentry>
- <term><varname>listen_on</varname></term>
- <listitem>
- <para>
- a list of pairs of address and port for
- <command>b10-stats-httpd</command> to listen HTTP requests on. The
- pair consists of the <varname>address</varname> string
- and <varname>port</varname> number. The default setting is the list
- of address 127.0.0.1 port 8000. If the server is started by the
- default setting being left, for example, the URL for XML document
- is http://127.0.0.1:8000/bind10/statistics/xml. And also IPv6
- addresses can be configured and they works in the runtime
- environment for dual stack. You can change the settings
- through <refentrytitle>bindctl</refentrytitle><manvolnum>8</manvolnum>.
