+# Telemetry on Percona XtraDB Cluster
+
+Percona telemetry fills in the gaps in our understanding of how you use Percona XtraDB Cluster to improve our products. Participation in the anonymous program is optional. You can opt-out if you prefer to not share this information.
+
+## What information is collected
+
+At this time, telemetry is added only to the Percona packages and Docker images. Percona XtraDB Cluster collects only information about the installation environment. Future releases may add additional metrics.
+
+Be assured that access to this raw data is rigorously controlled. Percona does not collect personal data. All data is anonymous and cannot be traced to a specific user. To learn more about our privacy practices, read our [Percona Privacy statement].
+
+An example of the data collected is the following:
+
+```JSON
+[{"id" : "c416c3ee-48cd-471c-9733-37c2886f8231",
+"product_family" : "PRODUCT_FAMILY_PXC",
+"instanceId" : "6aef422e-56a7-4530-af9d-94cc02198343",
+"createTime" : "2023-10-16T10:46:23Z",
+"metrics":
+[{"key" : "deployment","value" : "PACKAGE"},
+{"key" : "pillar_version","value" : "8.0.34-26"},
+{"key" : "OS","value" : "Oracle Linux Server 8.8"},
+{"key" : "hardware_arch","value" : "x86_64 x86_64"}]}]
+```
+
+## Disable telemetry
+
+Starting with Percona XtraDB Cluster 8.0.34-26-1, telemetry is enabled by default. If you decide not to send usage data to Percona, you can set the `PERCONA_TELEMETRY_DISABLE=1` environment variable for either the root user or in the operating system prior to the installation process.
+
+=== "Debian-derived distribution"
+
+    Add the environment variable before the install process.
+
+    ```{.bash data-prompt="$"}
+    $ sudo PERCONA_TELEMETRY_DISABLE=1 apt install percona-xtradb-cluster
+    ```
+
+=== "Red Hat-derived distribution"
+
+    Add the environment variable before the install process.
+
+    ```{.bash data-prompt="$"}
+    $ sudo PERCONA_TELEMETRY_DISABLE=1 yum install percona-xtradb-cluster
+    ```
+
+=== "DOCKER"
+
+    Add the environment variable when running a command in a new container.
+
+    ```{.bash data-prompt="$"}
+    $ docker run -d -e MYSQL_ROOT_PASSWORD=test1234# -e PERCONA_TELEMETRY_DISABLE=1 -e CLUSTER_NAME=pxc-cluster1 --name=pxc-node1 percona/percona-xtradb-cluster:8.0
