By default, the Database Lab Engine (DLE) collects non-personally identifiable telemetry data (applicable to the DLE versions 3.0.0 and later). This information helps the development team understand how the product is used and what to focus on next.

Fundamental principles of our telemetry implementation:

  • The data collected is minimal and non-personally identifiable. Particularly, the DLE instance ID is randomly generated and contains no identifying information.
  • See the sections below to find out what exactly is collected. Users are also encouraged to check the DLE source code to inspect how exactly the collection is implemented.
  • The raw telemetry data is never sent or processed by third parties outside's infrastructure (Google Cloud, USA regions). In an aggregated form, the usage statistics can be published periodically to help our growing community of users and contributors understand how DLE is used and what to develop next.
  • Telemetry is optional and can be disabled. However, as a growing community, we greatly appreciate the usage data users send to us, as it is very valuable in helping us make the Database Lab Engine a better product for everyone!

Collected data points#

Whenever a significant event happens, Database Lab Engine collects some information and sends it to the infrastructure making an HTTPS request. Each request contains four parts:

  • randomly generated "instance ID" (for example, instance_id: c6fgs68hmvj3sm2pbphg)
  • event timestamp (event_time)
  • event type (for example, event_type: engine_starged)
  • data relevant for particular event type (event_data)

Below you can find what data is collected and sent for each type of event.

Engine started#

{  "engine_version": "v3.0.0-20211220-1923",  "db_version": "11",  "pools": {    "fs_type": "zfs",    "number": 1,    "total_size": 369044992,    "total_used": 49280000  },  "restore": {    "mode": "logical",    "refreshing": "0 */6 * * *",    "jobs": [      "logicalDump",      "logicalRestore",      "logicalSnapshot"    ]  }}

Engine stopped#

{  "uptime": 46063}

Snapshot created#

event_data is empty for this event type.

Clone created#

{  "id": "2b887d9ff18be11c707f121218fc83dbdabae700",  "cloning_time": 0}

Clone reset#

{  "id": "2b887d9ff18be11c707f121218fc83dbdabae700",  "cloning_time": 0.848746942}

Clone destroyed#

{  "id": "2b887d9ff18be11c707f121218fc83dbdabae700"}


{  "level": "refresh_skipped",  "message": "Pool to perform full refresh not found. Skip refreshing"}

Disabling telemetry#

We will be very grateful if you allow us to collect statistics and help us keep improving our product.

We would greatly appreciate it if you would consider keeping telemetry enabled. The Database Lab Engine is an open-source product, and the anonymous telemetry data has a lot of value for the product development. Enabled telemetry is your contribution to the DLE development!

Nevertheless, if telemetry must be disabled in your case, change the flag global.telemetry.enabled to false in the DLE configuration file:

global:  telemetry:    enabled: false  ...

If the change is done when DLE is running, follow the DLE reconfiguration guide to apply the change without restart.

Enabling telemetry#

If telemetry was disabled earlier, you can enable it again changing the flag global.telemetry.enabled to true.

global:  telemetry:    enabled: true  ...

If the change is done when DLE is running, follow the DLE reconfiguration guide to apply the change without restart.
