From e7a75874a24c1bf19931d5b4b423a0daa7f9be6b Mon Sep 17 00:00:00 2001 From: Eddy Geez Date: Sat, 3 Sep 2011 09:10:21 -0400 Subject: [PATCH] interface plugin: Fix for bogus interfaces under Solaris. Under newer versions of Solaris, the method for finding network interfaces results in 'collectd' gathering statistics on an interface called 'mac', along with 16 interfaces named 'wrsmd0' through 'wrsmd15' (which are for WCI Remote Shared Memory). The 'mac' interface is especially problematic because it occurs multiple times, which results in warnings from rrdtool about insertions with the same timestamp.
