Chapter 4. Remote health monitoring with connected clusters
4.1. About remote health monitoring
OpenShift Container Platform collects telemetry and configuration data about your cluster and reports it to Red Hat by using the Telemeter Client and the Insights Operator. The data that is provided to Red Hat enables the benefits outlined in this document.
A cluster that reports data to Red Hat through Telemetry and the Insights Operator is considered a connected cluster.
Telemetry is the term that Red Hat uses to describe the information being sent to Red Hat by the OpenShift Container Platform Telemeter Client. Lightweight attributes are sent from connected clusters to Red Hat to enable subscription management automation, monitor the health of clusters, assist with support, and improve customer experience.
The Insights Operator gathers OpenShift Container Platform configuration data and sends it to Red Hat. The data is used to produce insights about potential issues that a cluster might be exposed to. These insights are communicated to cluster administrators on OpenShift Cluster Manager.
More information is provided in this document about these two processes.
Telemetry and Insights Operator benefits
Telemetry and the Insights Operator enable the following benefits for end-users:
- Enhanced identification and resolution of issues. Events that might seem normal to an end-user can be observed by Red Hat from a broader perspective across a fleet of clusters. Some issues can be more rapidly identified from this point of view and resolved without an end-user needing to open a support case or file a Jira issue.
-
Advanced release management. OpenShift Container Platform offers the
candidate
,fast
, andstable
release channels, which enable you to choose an update strategy. The graduation of a release fromfast
tostable
is dependent on the success rate of updates and on the events seen during upgrades. With the information provided by connected clusters, Red Hat can improve the quality of releases tostable
channels and react more rapidly to issues found in thefast
channels. - Targeted prioritization of new features and functionality. The data collected provides insights about which areas of OpenShift Container Platform are used most. With this information, Red Hat can focus on developing the new features and functionality that have the greatest impact for our customers.
- A streamlined support experience. You can provide a cluster ID for a connected cluster when creating a support ticket on the Red Hat Customer Portal. This enables Red Hat to deliver a streamlined support experience that is specific to your cluster, by using the connected information. This document provides more information about that enhanced support experience.
- Predictive analytics. The insights displayed for your cluster on OpenShift Cluster Manager are enabled by the information collected from connected clusters. Red Hat is investing in applying deep learning, machine learning, and artificial intelligence automation to help identify issues that OpenShift Container Platform clusters are exposed to.
4.1.1. About Telemetry
Telemetry sends a carefully chosen subset of the cluster monitoring metrics to Red Hat. The Telemeter Client fetches the metrics values every four minutes and thirty seconds and uploads the data to Red Hat. These metrics are described in this document.
This stream of data is used by Red Hat to monitor the 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 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 through support cases. All connected cluster information is used by Red Hat to help make OpenShift Container Platform better and more intuitive to use.
Additional resources
- See the OpenShift Container Platform update documentation for more information about updating or upgrading a cluster.

- See the upstream cluster-monitoring-operator source code for a list of the attributes that Telemetry gathers from Prometheus.
- Telemetry is installed and enabled by default. If you need to opt out of remote health reporting, see Opting out of remote health reporting.
4.1.2. About the Insights Operator
The Insights Operator periodically gathers configuration and component failure status and, by default, reports that data every two hours to Red Hat. This information enables Red Hat to assess configuration and deeper failure data than is reported through Telemetry.
Users of OpenShift Container Platform can display the report of each cluster in the Insights Advisor service on Red Hat Hybrid Cloud Console. If any issues have been identified, Insights provides further details and, if available, steps on how to solve a problem.
The Insights Operator does not collect identifying information, such as user names, passwords, or certificates. See Red Hat Insights Data & Application Security for information about Red Hat Insights data collection and controls.
Red Hat uses all connected cluster information to:
- Identify potential cluster issues and provide a solution and preventive actions in the Insights Advisor service on Red Hat Hybrid Cloud Console
- Improve OpenShift Container Platform by providing aggregated and critical information to product and support teams
- Make OpenShift Container Platform more intuitive
Additional resources
- The Insights Operator is installed and enabled by default. If you need to opt out of remote health reporting, see Opting out of remote health reporting.
4.1.2.1. Information collected by the Insights Operator
The following information is collected by the Insights Operator:
- General information about your cluster and its components to identify issues that are specific to your OpenShift Container Platform version and environment
- Configuration files, such as the image registry configuration, of your cluster to determine incorrect settings and issues that are specific to parameters you set
- Errors that occur in the cluster components
- Progress information of running updates, and the status of any component upgrades
- 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
- Cluster workload information transformed into discreet Secure Hash Algorithm (SHA) values, which allows Red Hat to assess workloads for security and version vulnerabilities without disclosing sensitive details
-
If an Operator reports an issue, information is collected about core OpenShift Container Platform pods in the
openshift-*
andkube-*
projects. This includes state, resource, security context, volume information, and more.
Additional resources
- See Showing data collected by the Insights Operator for details about how to review the data that is collected by the Insights Operator.
- The Insights Operator source code is available for review and contribution. See the Insights Operator upstream project for a list of the items collected by the Insights Operator.
4.1.3. Understanding Telemetry and Insights Operator data flow
The Telemeter Client collects selected time series data from the Prometheus API. The time series data is uploaded to api.openshift.com every four minutes and thirty seconds for processing.
The Insights Operator gathers selected data from the Kubernetes API and the Prometheus API into an archive. The archive is uploaded to OpenShift Cluster Manager every two hours for processing. The Insights Operator also downloads the latest Insights analysis from OpenShift Cluster Manager. This is used to populate the Insights status pop-up that is included in the Overview page in the OpenShift Container Platform web console.
All of the communication with Red Hat occurs over encrypted channels by using Transport Layer Security (TLS) and mutual certificate authentication. All of the data is encrypted in transit and at rest.
Access to the systems that handle customer data is controlled through multi-factor authentication and strict authorization controls. Access is granted on a need-to-know basis and is limited to required operations.

4.2.2. Showing data collected by the Insights Operator
You can review the data that is collected by the Insights Operator.
Prerequisites
-
Access to the cluster as a user with the
cluster-admin
role.
Procedure
Find the name of the currently running pod for the Insights Operator:
$ INSIGHTS_OPERATOR_POD=$(oc get pods --namespace=openshift-insights -o custom-columns=:metadata.name --no-headers --field-selector=status.phase=Running)
Copy the recent data archives collected by the Insights Operator:
$ oc cp openshift-insights/$INSIGHTS_OPERATOR_POD:/var/lib/insights-operator ./insights-data
The recent Insights Operator archives are now available in the insights-data
directory.
4.3. Opting out of remote health reporting
You may choose to opt out of reporting health and usage data for your cluster.
To opt out of remote health reporting, you must:
- Modify the global cluster pull secret to disable remote health reporting.
- Update the cluster to use this modified pull secret.
4.3.1. Consequences of disabling remote health reporting
In OpenShift Container Platform, customers can opt out of reporting usage information. However, connected clusters allow Red Hat to react more quickly to problems and better support our customers, as well as better understand how product upgrades impact clusters. Connected clusters also help to simplify the subscription and entitlement process and enable the OpenShift Cluster Manager service to provide an overview of your clusters and their subscription status.
Red Hat strongly recommends leaving health and usage reporting enabled for pre-production and test clusters even if it is necessary to opt out for production clusters. This allows Red Hat to be a participant in qualifying OpenShift Container Platform in your environments and react more rapidly to product issues.
Some of the consequences of opting out of having a connected cluster are:
- Red Hat will not be able to monitor the success of product upgrades or the health of your clusters without a support case being opened.
- Red Hat will not be able to use configuration data to better triage customer support cases and identify which configurations our customers find important.
- The OpenShift Cluster Manager will not show data about your clusters including health and usage information.
- Your subscription entitlement information must be manually entered via console.redhat.com without the benefit of automatic usage reporting.
In restricted networks, Telemetry and Insights data can still be reported through appropriate configuration of your proxy.
4.3.2. Modifying the global cluster pull secret to disable remote health reporting
You can modify your existing global cluster pull secret to disable remote health reporting. This disables both Telemetry and the Insights Operator.
Prerequisites
-
You have access to the cluster as a user with the
cluster-admin
role.
Procedure
Download the global cluster pull secret to your local file system.
$ oc extract secret/pull-secret -n openshift-config --to=.
-
In a text editor, edit the
.dockerconfigjson
file that was downloaded. Remove the
cloud.openshift.com
JSON entry, for example:"cloud.openshift.com":{"auth":"<hash>","email":"<email_address>"}
- Save the file.
You can now update your cluster to use this modified pull secret.
4.3.3. Registering your disconnected cluster
Register your disconnected OpenShift Container Platform cluster on the Red Hat Hybrid Cloud Console so that your cluster is not impacted by the consequences listed in the section named "Consequences of disabling remote health reporting".
By registering your disconnected cluster, you can continue to report your subscription usage to Red Hat. In turn, Red Hat can return accurate usage and capacity trends associated with your subscription, so that you can use the returned information to better organize subscription allocations across all of your resources.
Prerequisites
-
You are logged in to the OpenShift Container Platform web console as
cluster-admin
. - You can log in to the Red Hat Hybrid Cloud Console.
Procedure
- Go to the Register disconnected cluster web page on the Red Hat Hybrid Cloud Console.
- Optional: To access the Register disconnected cluster web page from the home page of the Red Hat Hybrid Cloud Console, go to the Clusters navigation menu item and then select the Register cluster button.
- Enter your cluster’s details in the provided fields on the Register disconnected cluster page.
- From the Subscription settings section of the page, select the subcription settings that apply to your Red Hat subscription offering.
- To register your disconnected cluster, select the Register cluster button.
Additional resources

- How does the subscriptions service show my subscription data?(Getting Started with the Subscription Service)
4.3.4. Updating the global cluster pull secret
You can update the global pull secret for your cluster by either replacing the current pull secret or appending a new pull secret.
The procedure is required when users use a separate registry to store images than the registry used during installation.
Prerequisites
-
You have access to the cluster as a user with the
cluster-admin
role.
Procedure
Optional: To append a new pull secret to the existing pull secret, complete the following steps:
Enter the following command to download the pull secret:
$ oc get secret/pull-secret -n openshift-config --template='{{index .data ".dockerconfigjson" | base64decode}}' ><pull_secret_location> 1
- 1
- Provide the path to the pull secret file.
Enter the following command to add the new pull secret:
$ oc registry login --registry="<registry>" \ 1 --auth-basic="<username>:<password>" \ 2 --to=<pull_secret_location> 3
Alternatively, you can perform a manual update to the pull secret file.
Enter the following command to update the global pull secret for your cluster:
$ oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=<pull_secret_location> 1
- 1
- Provide the path to the new pull secret file.
This update is rolled out to all nodes, which can take some time depending on the size of your cluster.
NoteAs of OpenShift Container Platform 4.7.4, changes to the global pull secret no longer trigger a node drain or reboot.
4.4. Enabling remote health reporting
If you or your organization have disabled remote health reporting, you can enable this feature again. You can see that remote health reporting is disabled from the message "Insights not available" in the Status tile on the OpenShift Container Platform Web Console Overview page.
To enable remote health reporting, you must Modify the global cluster pull secret with a new authorization token.
Enabling remote health reporting enables both Insights Operator and Telemetry.
4.4.1. Modifying your global cluster pull secret to enable remote health reporting
You can modify your existing global cluster pull secret to enable remote health reporting. If you have previously disabled remote health monitoring, you must first download a new pull secret with your console.openshift.com
access token from Red Hat OpenShift Cluster Manager.
Prerequisites
-
Access to the cluster as a user with the
cluster-admin
role. - Access to OpenShift Cluster Manager.
Procedure
- Navigate to https://console.redhat.com/openshift/downloads.

pull-secret.txt
containing yourcloud.openshift.com
access token in JSON format downloads:{ "auths": { "cloud.openshift.com": { "auth": "<your_token>", "email": "<email_address>" } }
Download the global cluster pull secret to your local file system.
$ oc get secret/pull-secret -n openshift-config --template='{{index .data ".dockerconfigjson" | base64decode}}' > pull-secret
Make a backup copy of your pull secret.
$ cp pull-secret pull-secret-backup
-
Open the
pull-secret
file in a text editor. -
Append the
cloud.openshift.com
JSON entry frompull-secret.txt
intoauths
. - Save the file.
Update the secret in your cluster.
oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=pull-secret
It may take several minutes for the secret to update and your cluster to begin reporting.
Verification
- Navigate to the OpenShift Container Platform Web Console Overview page.
- Insights in the Status tile reports the number of issues found.

4.7.2. Uploading an Insights Operator archive
You can manually upload an Insights Operator archive to console.redhat.com to diagnose potential issues.
Prerequisites
-
You are logged in to OpenShift Container Platform as
cluster-admin
. - You have a workstation with unrestricted internet access.
- You have created a copy of the Insights Operator archive.
Procedure
Download the
dockerconfig.json
file:$ oc extract secret/pull-secret -n openshift-config --to=.
Copy your
"cloud.openshift.com"
"auth"
token from thedockerconfig.json
file:{ "auths": { "cloud.openshift.com": { "auth": "<your_token>", "email": "asd@redhat.com" } }
Upload the archive to console.redhat.com:
$ curl -v -H "User-Agent: insights-operator/one10time200gather184a34f6a168926d93c330 cluster/<cluster_id>" -H "Authorization: Bearer <your_token>" -F "upload=@<path_to_archive>; type=application/vnd.redhat.openshift.periodic+tar" https://console.redhat.com/api/ingress/v1/upload
where
<cluster_id>
is your cluster ID,<your_token>
is the token from your pull secret, and<path_to_archive>
is the path to the Insights Operator archive.If the operation is successful, the command returns a
"request_id"
and"account_number"
:Example output
* Connection #0 to host console.redhat.com left intact {"request_id":"393a7cf1093e434ea8dd4ab3eb28884c","upload":{"account_number":"6274079"}}%
Verification steps
- Log in to https://console.redhat.com/openshift.
- Click the Clusters menu in the left pane.
- To display the details of the cluster, click the cluster name.
Open the Insights Advisor tab of the cluster.
If the upload was successful, the tab displays one of the following:
- Your cluster passed all recommendations, if Insights Advisor did not identify any issues.
- A list of issues that Insights Advisor has detected, prioritized by risk (low, moderate, important, and critical).
4.7.3. Enabling Insights Operator data obfuscation
You can enable obfuscation to mask sensitive and identifiable IPv4 addresses and cluster base domains that the Insights Operator sends to console.redhat.com.
Although this feature is available, Red Hat recommends keeping obfuscation disabled for a more effective support experience.
Obfuscation assigns non-identifying values to cluster IPv4 addresses, and uses a translation table that is retained in memory to change IP addresses to their obfuscated versions throughout the Insights Operator archive before uploading the data to console.redhat.com.
For cluster base domains, obfuscation changes the base domain to a hardcoded substring. For example, cluster-api.openshift.example.com
becomes cluster-api.<CLUSTER_BASE_DOMAIN>
.
The following procedure enables obfuscation using the support
secret in the openshift-config
namespace.
Prerequisites
-
You are logged in to the OpenShift Container Platform web console as
cluster-admin
.
Procedure
-
Navigate to Workloads
Secrets. - Select the openshift-config project.
-
Search for the support secret using the Search by name field. If it does not exist, click Create
Key/value secret to create it. - Click the Options menu , and then click Edit Secret.
- Click Add Key/Value.
-
Create a key named
enableGlobalObfuscation
with a value oftrue
, and click Save. -
Navigate to Workloads
Pods -
Select the
openshift-insights
project. -
Find the
insights-operator
pod. -
To restart the
insights-operator
pod, click the Options menu , and then click Delete Pod.
Verification
-
Navigate to Workloads
Secrets. - Select the openshift-insights project.
- Search for the obfuscation-translation-table secret using the Search by name field.
If the obfuscation-translation-table
secret exists, then obfuscation is enabled and working.
Alternatively, you can inspect /insights-operator/gathers.json
in your Insights Operator archive for the value "is_global_obfuscation_enabled": true
.

4.8. Importing simple content access entitlements with Insights Operator
Insights Operator periodically imports your simple content access entitlements from OpenShift Cluster Manager and stores them in the etc-pki-entitlement
secret in the openshift-config-managed
namespace. Simple content access is a capability in Red Hat subscription tools which simplifies the behavior of the entitlement tooling. This feature makes it easier to consume the content provided by your Red Hat subscriptions without the complexity of configuring subscription tooling.
Insights Operator imports simple content access entitlements every eight hours, but can be configured or disabled using the support
secret in the openshift-config
namespace.
Simple content access must be enabled in Red Hat Subscription Management for the importing to function.
Additional resources
- See About simple content access in the Red Hat Subscription Central documentation, for more information about simple content access.
- See Using Red Hat subscriptions in builds for more information about using simple content access entitlements in OpenShift Container Platform builds.
4.8.1. Configuring simple content access import interval
You can configure how often the Insights Operator imports the simple content access entitlements using the support
secret in the openshift-config
namespace. The entitlement import normally occurs every eight hours, but you can shorten this interval if you update your simple content access configuration in Red Hat Subscription Management.
This procedure describes how to update the import interval to one hour.
Prerequisites
-
You are logged in to the OpenShift Container Platform web console as
cluster-admin
.
Procedure
-
Navigate to Workloads
Secrets. - Select the openshift-config project.
-
Search for the support secret using the Search by name field. If it does not exist, click Create
Key/value secret to create it. - Click the Options menu , and then click Edit Secret.
- Click Add Key/Value.
Create a key named
scaInterval
with a value of1h
, and click Save.NoteThe interval
1h
can also be entered as60m
for 60 minutes.
4.8.2. Disabling simple content access import
You can disable the importing of simple content access entitlements using the support
secret in the openshift-config
namespace.
Prerequisites
-
You are logged in to the OpenShift Container Platform web console as
cluster-admin
.
Procedure
-
Navigate to Workloads
Secrets. - Select the openshift-config project.
-
Search for the support secret using the Search by name field. If it does not exist, click Create
Key/value secret to create it. - Click the Options menu , and then click Edit Secret.
- Click Add Key/Value.
Create a key named
scaPullDisabled
with a value oftrue
, and click Save.The simple content access entitlement import is now disabled.
NoteTo enable the simple content access import again, edit the
support
secret and delete thescaPullDisabled
key.
