We already have a robust set of opt-in and opt-out procedures; no need to require the user to enable the module. Signed-off-by: Sage Weil <sage@redhat.com>

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.
|
|
|
|
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, radosgws, 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
|
|
|
|
* **ident** (default: on): 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, or hostnames.
|
|
|
|
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 over HTTPS to *telemetry.ceph.com*.
|
|
|
|
Sample report
|
|
-------------
|
|
|
|
You can look at what data is reported at any time with the command::
|
|
|
|
ceph telemetry show
|
|
|
|
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 telemetry show
|
|
|
|
Enabling Telemetry
|
|
------------------
|
|
|
|
To allow the *telemetry* module to start sharing data,::
|
|
|
|
ceph telemetry on
|
|
|
|
Telemetry can be disabled at any time with::
|
|
|
|
ceph telemetry off
|
|
|
|
Interval
|
|
--------
|
|
|
|
The module compiles and sends a new report every 72 hours by default.
|
|
You can adjust this interval with::
|
|
|
|
ceph config set mgr mgr/telemetry/interval 24 # report every day
|
|
|
|
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
|
|
