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)
Comment 4 damien Power 2017-03-30 09:30:11 EDT 
this plugin is upstreamed to collectd
Comment 8 Matthias Runge 2017-07-12 05:36:08 EDT 
how to test: yum install collectd-hugepages
and see a hugepages metering showing up in grafana.
Comment 10 Leonid Natapov 2017-09-11 10:14:11 EDT 
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.
Comment 11 Leonid Natapov 2017-09-11 10:25:23 EDT 
Pls,consider to move to osp13.

Comment 25 Matthias Runge 2018-02-19 04:41:39 EST
