Fixed In Version: collectd-5.11.0-10.el8ost
Doc Type: Bug Fix
Doc Text:
Libvirt was updated and as a result provides more metrics. Due to API changes, collectd was incompatible, resulting in a potential application crash. With this update, collectd was adjusted to provide hugepage usage via the virt plugin. The hugepages metric is exposed via the virt plugin and collectd was adjusted to match the API changes so that the application no longer crashes when pulling the virt metrics.
