Percona Telemetry is enabled even after disabing via PERCONA_TELEMETRY_DISABLE=1

Description

How to reproduce:

  1. Install PXC with telemetry disabled; for this test, it was used PXC 8.0.37-29-1(latest release) on Ubuntu 22.04:

sudo PERCONA_TELEMETRY_DISABLE=1 apt install percona-xtradb-cluster

  1. It automatically lists and, therefore, installs the percona-telemetry-agent package.

  2. After completion, if we check, we can see it was installed and enabled:

Expected behavior:

With the intention of PERCONA_TELEMETRY_DISABLE=1 no related package or further telemetry agent should be installed/enabled.

Hi ,

 

Thank you for double-checking that.

I wiped out any trace of the previous installation and installed the PXC with PERCONA TELEMETRY DISABLE=1 from scratch, and it didn't enable this time.

Hi ,

Setting the environment variable PERCONA_TELEMETRY_DISABLE=1 in the command sudo PERCONA_TELEMETRY_DISABLE=1 apt install percona-xtradb-cluster disables only the installation-time telemetry.

The percona-telemetry-agent package is installed as a part of continuous telemetry and the package is installed as a dependency during the installation of percona-xtradb-cluster and other products. The only way to disable continuous telemetry is to disable the telemetry agent service - https://docs.percona.com/percona-xtradb-cluster/8.0/telemetry.html#disable-the-telemetry-agent .

The file /usr/local/percona/telemetry_uuid is generated during installation-time telemetry. I verified disabling the installation-time telemetry during the installation of percona-xtradb-cluster using the command PERCONA_TELEMETRY_DISABLE=1 apt install percona-xtradb-cluster and no telemetry_uuid file was generated. Looks like the telemetry_uuid file in your system is from an older installation. Could you please remove the old telemetry_uuid file and then try installing PXC with PERCONA_TELEMETRY_DISABLE=1 ?

Thank you.
