collectd

collectd is a daemon which collects system and application performance metrics periodically and delivers a method to store the values in different ways. It collects metrics from various sources, for example, the operating system platform, user applications, system and user log files, and external devices, and accumulates this information or makes it available over the network.

In Ceph Metrics, the Ceph nodes will have collectd installed along with collector plugins from cephmetrics-collectd.
