# Telemetry

When you operate a node on an Aptos network, your node can be set to send telemetry data to Aptos Labs. You can disable telemetry at any point. If telemetry remains enabled, Aptos node binary will send telemetry data in the background.

The Aptos node binary running on your node collects telemetry data such as software version, operating system information and the IP address of your node. This telemetry data is used to enhance the decentralization of the network.

No personal information is collected

The Aptos node binary does not collect personal information such as usernames or email addresses.

## Metrics collected​

### Node information​

The public IP address of the node and core metrics, including node type, synced version and number of network connections.

### CLI telemetry​

The commands and subcommands run by the Aptos CLI tool.

### Build information​

Rust build information including the versions of Rust, cargo, build target architecture and the build tag.

### System information​

System information including operating system information (including versions), hardware information and resource utilization (including CPU, memory and disk).

### Others​

• Metrics: All the Prometheus metrics that are collected within the node.
• Logs: Logs of warn-level and higher level, with the ability to collect up to debug logs.

## Disabling telemetry​

On macOS and Linux, you can set the following environment variables to control the metrics sent by your node. For example, to disable all telemetry, set the APTOS_DISABLE_TELEMETRY environment variable to true as shown below:

export APTOS_DISABLE_TELEMETRY=true

The above example only disables telemetry for a single session in the current terminal where you ran the above command. To disable it permanently on your node, include it in your startup profile, as below:

echo "export APTOS_DISABLE_TELEMETRY=true" >> ~/.profilesource ~/.profile
All telemetry is ON by default.

All the below variables are set by default to false, i.e., sending of these telemetry metrics is enabled. Set them to true to disable telemetry.

• APTOS_DISABLE_TELEMETRY: This disables all telemetry emission from the node including sending to the GA4 service.
• APTOS_FORCE_ENABLE_TELEMETRY: This overrides the chain ID check and forces the node to send telemetry regardless of whether remote service accepts or not.
• APTOS_DISABLE_TELEMETRY_PUSH_METRICS: This disables sending the Prometheus metrics.
• APTOS_DISABLE_TELEMETRY_PUSH_LOGS: This disables sending the logs.
• APTOS_DISBALE_TELEMETRY_PUSH_EVENTS: This disables sending the custom events.
• APTOS_DISABLE_LOG_ENV_POLLING: This disables the dynamic ability to send verbose logs.
• APTOS_DISABLE_PROMETHEUS_NODE_METRICS: This disables sending the node resource metrics such as system CPU, memory, etc.
