3. Description:

collectd is a host-based system statistics collection daemon that gathers
metrics from various sources periodically, such as the operating system,
applications, log files and devices, and storage clusters. As the daemon
does not start up each time it updates files, it has a low system

responsible for gathering metrics from Red Hat Gluster Storage clusters.

(CVE-2017-16820)
