BIND statistics

Sun Aug 25 19:10:03 UTC 2024

Hi,

I'm mostly running BIND 9.18.x, and have configured statistics
publishing via

statistics-channels {
        inet 127.0.0.1 port 8053 allow { 127.0.0.1; };
        inet "actual-address" port 8053 allow { prefix1/24; prefix2/24; };
};

I've started testing 9.20.x.

I see BIND 9.20.x stats publishing is ... different.

If I use firefox and visit http://actual-address:8053/ with BIND
9.18.x, I get a reasonably rendered HTML display which is easy to
view.

Not so for BIND 9.20.x; I get an XML document which firefox (in
this particular case version 120.0) informs me at the top

   This XML file does not appear to have any style information
   associated with it. The document tree is shown below.

and the document starts with

<a class="tabletoggle" href="#" style="font-size:small">Show/Hide</a>
'); $(".tabletoggle").click(function(){ var n = $(this).closest("h2,h3,h4").next(); if (n.is("script")) { n = n.next(); } if (n.is("div")) { n.toggleClass("hidden"); n = n.next(); } if (n.is("table")) { n.toggleClass("hidden"); } return false; }); });
</script>

and is quite different from what BIND 9.18.x presents:

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="/bind9.xsl"?>
<statistics version="3.13"><server><boot-time>2024-08-16T09:03:10.730Z</boot-time>

etc. etc.

The question is: am I alone in experiencing this?

It also looks like I'll have to find out why collecting BIND
stats via collectd (5.12.0) no longer works after upgrading to
9.20.x.

Best regards,
