Hugepages plugin: This new plugin reports the number of used and free hugepages on Linux. Thanks to Jaroslav Safka, Maryam Tahhan, Kim Jones and Florian Forster. #1799 (https://github.com/collectd/collectd/pull/1799)
this plugin is upstreamed to collectd
how to test: yum install collectd-hugepages and see a hugepages metering showing up in grafana.
The package is in the opstools repo and can be installed by running yum install but we should do container integration for this plugin. We need to change default container images to include huje pages plugin.
Pls,consider to move to osp13.
Upstream in collectd v5.7.2.
Please provide instructions how to configure/test
Leonid, the config I could find is this here: https://collectd.org/documentation/manpages/collectd.conf.5.shtml#plugin_hugepages
Once the plugin is loaded, one should find a plugin in grafana, beginning with hugepages_
new build adds config
