X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e274d13b135ccbfe8d6abccf69c093313b38bc85;p=varnish

Added -x option to get XML output. As with the -1 option, it prints it once and quits, and you can choose what fields to include with the -f option. Example XML output is

<?xml version="1.0"?>
<varnishstat timestamp="2009-02-25T08:45:02">
	<stat>
		<name>client_req</name>
		<value>2656016</value>
		<description>Client requests received</description>
	</stat>
</varnishstat>

varnishstat.xsd contains the XML schema for the output.
