.. _telemetry: 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 * **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 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 the module ------------------- The module must first be enabled. Note that even if the module is enabled, telemetry is still "off" by default, so simply enabling the module will *NOT* result in any data being shared.:: ceph mgr module enable telemetry 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 ' ceph config set mgr mgr/telemetry/description 'My first Ceph cluster' ceph config set mgr mgr/telemetry/channel_ident true
