From 93ff4cc743c3aa5581ba4eb1789a784c06c4cc3b Mon Sep 17 00:00:00 2001 From: Nick Hainke Date: Fri, 29 Jan 2021 10:40:14 +0100 Subject: [PATCH] collectd: add plugin to compare ipv4,ipv6 stats Add "ipstatistics"-plugin. This plugin parses "/proc/net/netstat" and "/proc/net/snmp6" to get the overall ipv4 and ipv6 usage.
