In the releases notes, even for the 4.6 rc, I see: https://www.ovirt.org/release/4.1.6/ ... OpsTools currently includes collectd 5.7.0, and the write_http plugin is packaged separately. But if I check the current state: yum list collectd-write_http collectd ... collectd.x86_64 5.7.2-1.el7 @centos-opstools-release collectd-write_http.x86_64 5.7.2-1.el7 @centos-opstools-release So I think the warning is not needed any more. One can uses both ovirt and epel without any special check.
