+Telemetry Module
+================
+
+The telemetry module sends anonymous data about the cluster back to the Ceph
+developers to help understand how Ceph is used and what problems users may
+be experiencing.
+
+This data is visualized on `public dashboards <https://telemetry-public.ceph.com/>`_
+that allow the community to quickly see summary statistics on how many clusters
+are reporting, their total capacity and OSD count, and version distribution
+trends.
+
+Channels
+--------
+
+The telemetry report is broken down into several "channels", each with
+a different type of information.  Assuming telemetry has been enabled,
+individual channels can be turned on and off.  (If telemetry is off,
+the per-channel setting has no effect.)
+
+* **basic** (default: on): Basic information about the cluster
+
+    - capacity of the cluster
+    - number of monitors, managers, OSDs, MDSs, object gateways, or other daemons
+    - software version currently being used
+    - number and types of RADOS pools and CephFS file systems
+    - names of configuration options that have been changed from their
+      default (but *not* their values)
+
+* **crash** (default: on): Information about daemon crashes, including
+
+    - type of daemon
+    - version of the daemon
+    - operating system (OS distribution, kernel version)
+    - stack trace identifying where in the Ceph code the crash occurred
+
+* **device** (default: on): Information about device metrics, including
+
+    - anonymized SMART metrics
+
+* **ident** (default: off): User-provided identifying information about
+  the cluster
+
+    - cluster description
+    - contact email address
+
+The data being reported does *not* contain any sensitive
+data like pool names, object names, object contents, hostnames, or device
+serial numbers.
+
+It contains counters and statistics on how the cluster has been
+deployed, the version of Ceph, the distribution of the hosts and other
+parameters which help the project to gain a better understanding of
+the way Ceph is used.
+
+Data is sent secured to *https://telemetry.ceph.com*.
+
+Sample report
+-------------
+
+You can look at what data is reported at any time with the command::
+
+  ceph telemetry show
+
+To protect your privacy, device reports are generated separately, and data such
+as hostname and device serial number is anonymized. The device telemetry is
+sent to a different endpoint and does not associate the device data with a
+particular cluster. To see a preview of the device report use the command::
+
+  ceph telemetry show-device
+
+Please note: In order to generate the device report we use Smartmontools
+version 7.0 and up, which supports JSON output. 
+If you have any concerns about privacy with regard to the information included in
+this report, please contact the Ceph developers.
+
+Channels
+--------
+
+Individual channels can be enabled or disabled with::
+
+  ceph config set mgr mgr/telemetry/channel_ident false
+  ceph config set mgr mgr/telemetry/channel_basic false
+  ceph config set mgr mgr/telemetry/channel_crash false
+  ceph config set mgr mgr/telemetry/channel_device false
+  ceph telemetry show
+  ceph telemetry show-device
+
+Enabling Telemetry
+------------------
+
+To allow the *telemetry* module to start sharing data::
+
+  ceph telemetry on
+
+Please note: Telemetry data is licensed under the Community Data License
+Agreement - Sharing - Version 1.0 (https://cdla.io/sharing-1-0/). Hence,
+telemetry module can be enabled only after you add '--license sharing-1-0' to
+the 'ceph telemetry on' command.
+
+Telemetry can be disabled at any time with::
+
+  ceph telemetry off
+
+Interval
+--------
+
+The module compiles and sends a new report every 24 hours by default.
+You can adjust this interval with::
+
+  ceph config set mgr mgr/telemetry/interval 72    # report every three days
+
+Status
+--------
+
+The see the current configuration::
+
+  ceph telemetry status
+
+Manually sending telemetry
+--------------------------
+
+To ad hoc send telemetry data::
+
+  ceph telemetry send
+
+In case telemetry is not enabled (with 'ceph telemetry on'), you need to add
+'--license sharing-1-0' to 'ceph telemetry send' command.
+
+Sending telemetry through a proxy
+---------------------------------
+
+If the cluster cannot directly connect to the configured telemetry
+endpoint (default *telemetry.ceph.com*), you can configure a HTTP/HTTPS
+proxy server with::
+
+  ceph config set mgr mgr/telemetry/proxy https://10.0.0.1:8080
+
+You can also include a *user:pass* if needed::
+
+  ceph config set mgr mgr/telemetry/proxy https://ceph:telemetry@10.0.0.1:8080
+
+
+Contact and Description
+-----------------------
+
+A contact and description can be added to the report.  This is
+completely optional, and disabled by default.::
+
+  ceph config set mgr mgr/telemetry/contact 'John Doe <john.doe@example.com>'
+  ceph config set mgr mgr/telemetry/description 'My first Ceph cluster'
+  ceph config set mgr mgr/telemetry/channel_ident true
+
