[collectd] conntrack patch against 4.6.2

Tomasz Pala gotar at polanet.pl
Mon Mar 30 11:23:33 CEST 2009


Hello,

I've adapted entropy plugin to get nf_conntrack entries, which is
important on Linux routers. Attached patch.

BTW you may want to take a look at PLD Linux spec file at
http://cvs.pld-linux.org/cgi-bin/cvsweb/SPECS/collectd.spec or
http://cvs.pld-linux.org/cgi-bin/cvsweb.cgi/SPECS/collectd.spec
as it's much more complex than Fedora, RH or SLES ones which are shipped
in contrib.
