Comment 1 Matthias Runge 2017-10-27 10:14:29 UTC

On a centos 7 test machine using a build from epel:
The version coming from EPEL is 5.7.1

first run, it didn't work
second one, after fully updating the machine, it works

Re-testing with collectd-5.7.2 from centos-opstools does not show any issues

Comment 2 Matthias Runge 2017-10-28 08:54:28 UTC

5.7.2 from osp works, once fixing the config issue https://bugzilla.redhat.com/show_bug.cgi?id=1507203

Comment 12 Lon Hohberger 2018-08-16 10:38:40 UTC

According to our records, this should be resolved by collectd-5.8.0-10.el7ost.  This build is available now.

Comment 13 Leonid Natapov 2019-01-10 14:27:27 UTC

collectd-netlink-5.8.0-12.el7ost.x86_64

Created conf file for netlink plugin:

LoadPlugin "netlink"
<Plugin "netlink">
 Interface "eth0"
</Plugin>
