Comment 1 Matthias Runge 2017-01-03 13:20:47 UTC

https://collectd.org/news.shtml
lists a dpdk plugin to be available in collectd-5.7.0 (and later)

Comment 4 Matthias Runge 2017-01-13 15:32:09 UTC

actually the build missed the plugin

Comment 7 Prateek Arora 2017-01-17 08:57:12 UTC

Here are my findings

The plugin has some linking problems. Enabling it with collectd throws the following errors repeatedly

In file included from /usr/include/dpdk/rte_ether.h:50:0,
                 from /usr/include/dpdk/rte_ethdev.h:185,
                 from dpdkstat.c:50:

The errors are related to the data reader from dpdk and as such collectd is not able to get the dpdk data.
