Telemetry plugin
================
The telemetry plugin sends anonymous data about the cluster, in which it is running, back to the Ceph project.

The data being sent back to the project does not contain any sensitive data like pool names, object names, object contents or hostnames.

It contains counters and statistics on how the cluster has been deployed, the version of Ceph, the distribition of the hosts and other parameters which help the project to gain a better understanding of the way Ceph is used.

Data is sent over HTTPS to *telemetry.ceph.com*

Enabling
