Tectonic's pricing is determined, in part, by the number of Kubernetes nodes within a cluster. For each cluster, information about each Kubernetes node is collected in order to facilitate billing and support. For example, this information can be used to send notifications if purchased limits have been exceeded or it can be accessed by the CoreOS support team to do initial triage of support issues.
This information is never shared outside of CoreOS. For more details, see the full CoreOS Master Subscription and Services Agreement.
The following list details the types of data collected and the purpose:
Billing Telemetry for Future Use
Periodically the Tectonic Stats Collector running on-cluster will send a payload with these metrics to the stats collector endpoint located at https://stats-collector.tectonic.com/.
Additional metrics may be added to this list in response to supportability and billing changes of the product. Questions or concerns may be directed to email@example.com.
