My suggestion would be to look at the JSON metadata functionality:
http://icecast.org/docs/icecast-2.4.1/server-stats.html
If you aren't running Icecast >= 2.4.1 (latest is 2.4.4), then you
*really* should consider upgrading as there have been important security
fixes and general improvements.

You can query /status-json.xsl directly from within a web page.

The reported error is in name resolution. So this is not really Icecast
related - something, somewhere fails to resolve the FQDN that is part of
$stream_url. You'll have to investigate this yourself.

Icecast (no CamelCase, please!) is not involved in the problem that you
are seeing.
"It was DNS, It's always DNS!"

You need to investigate your DNS resolution problem - Anywhere between
that nodejs and the authoritative nameserver for the FQDN.

My recommendation remains to just use the JSON API and forget nodejs.
You will probably still have to address your DNS reliability.
