This topic describes how Tanzu Telemetry Collector transmits, stores, and secures collected data.


Tanzu Telemetry Collector collects configuration data about your foundation. Tanzu Telemetry Collector does not collect any personal data or information related to an identified or identifiable natural person. For example, it does not collect data on passwords, private keys, or other authentication-type tools.

Note Tanzu Telemetry Collector collects configuration data for all services installed on a foundation. This may include partner tile data.

Security Measures

Tanzu Telemetry Collector connects to Tanzu Operations Manager and optionally the Reporting app, task, and service instance usage on any VMware Tanzu Cloud Foundry (PCF) foundation that has provided valid credentials. After Tanzu Telemetry Collector collects data, this data may be transmitted to VMware. The data is stored securely in Google Cloud Platform (GCP).

Tanzu Telemetry Collector secures data during transmission using the following measures:

  • HTTPS connections when communicating
  • User-specific credentials to authenticate HTTPS requests to VMware
