About remote health monitoring

OpenShift Container Platform collects anonymized aggregated information about the health, usage, and size of clusters and reports it to Red Hat via two integrated components: Telemetry and the Insights Operator. This information allows Red Hat to improve OpenShift Container Platform and to react to issues that impact customers more quickly. This also simplifies the subscription and entitlement process for Red Hat customers and enables the Red Hat OpenShift Cluster Manager service to provide an overview of your clusters and their health and subscription status.

A cluster that reports data to Red Hat via Telemetry and the Insights Operator is considered a connected cluster.

About Telemetry

Telemetry sends a carefully chosen subset of the cluster monitoring metrics to Red Hat. These metrics are sent continuously and describe:

  • The size of an OpenShift Container Platform cluster

  • The health and status of OpenShift Container Platform components

  • The health and status of any upgrade being performed

  • Limited usage information about OpenShift Container Platform components and features

  • Summary info about alerts reported by the cluster monitoring component

This continuous stream of data is used by Red Hat to monitor the health of clusters in real time and to react as necessary to problems that impact our customers. It also allows Red Hat to roll out OpenShift Container Platform upgrades to customers so as to minimize service impact and continuously improve the upgrade experience.

This debugging information is available to Red Hat Support and engineering teams with the same restrictions as accessing data reported via support cases. All connected cluster information is used by Red Hat to help make OpenShift Container Platform better and more intuitive to use. None of the information is shared with third parties.

Information collected by Telemetry

Primary information collected by Telemetry includes:

  • The number of updates available per cluster

  • Channel and image repository used for an update

  • The number of errors that occurred during an update

  • Progress information of running updates

  • The number of machines per cluster

  • The number of CPU cores and size of RAM of the machines

  • The number of members in the etcd cluster and number of objects currently stored in the etcd cluster

  • The number of CPU cores and RAM used per machine type - infra or master

  • The number of CPU cores and RAM used per cluster

  • Use of OpenShift Container Platform framework components per cluster

  • The version of the OpenShift Container Platform cluster

  • Health, condition, and status for any OpenShift Container Platform framework component that is installed on the cluster, for example Cluster Version Operator, Cluster Monitoring, Image Registry, and Elasticsearch for Logging

  • A unique random identifier that is generated during installation

  • The name of the platform that OpenShift Container Platform is deployed on, such as Amazon Web Services

Telemetry does not collect identifying information such as user names, passwords, or the names or addresses of user resources.

About the Insights Operator

The Insights Operator periodically gathers anonymized configuration and component failure status and reports that to Red Hat. This is a subset of the information captured by the must-gather tool and allows Red Hat to assess important configuration and deeper failure data than is reported via Telemetry. This data is sent several times a day and describes:

  • Important configuration information about the environment that the cluster runs in

  • Details about the state of the cluster and its major components

  • Debugging information about infrastructure pods or nodes that are reporting failures

This debugging information is available to Red Hat Support and engineering teams with the same restrictions as accessing data reported via support cases. All connected cluster information is used by Red Hat to help make OpenShift Container Platform better and more intuitive to use. None of the information is shared with third parties.

Information collected by the Insights Operator

Primary information collected by the Insights Operator includes:

  • The version of the cluster and its components, as well as the unique cluster identifier

  • Channel and image repository used for an update

  • Details about errors that have occurred in the cluster components

  • Progress and health information of running updates and the status of any component upgrades

  • Anonymized details about the cluster configuration that is relevant to Red Hat Support

  • Details about any Technology Preview or unsupported configurations that might impact Red Hat Support

  • Details of the platform that OpenShift Container Platform is deployed on, such as Amazon Web Services, and the region that the cluster is located in

  • Information about pods of degraded OpenShift Container Platform cluster Operators

  • Information about nodes marked as NotReady

  • Events for all namespaces listed as "related objects" for Degraded operator

  • Anonymized certificate signing requests (CSR) and information about the validity of certificates

The Insights Operator does not collect identifying information such as user names, passwords, or the names or addresses of user resources.
