Chapter 9. Monitoring hosts by using Red Hat Lightspeed in Red Hat Hybrid Cloud Console

You can use the Red Hat Lightspeed advisor service in the Red Hat Hybrid Cloud Console to assess system health on hosts running Red Hat Enterprise Linux. You can use the Red Hat Lightspeed dashboard in the Red Hat Hybrid Cloud Console to quickly analyze recommendations for remediation, vulnerabilities, and more.

If you use Red Hat Lightspeed in the Red Hat Hybrid Cloud Console:

  • You can use Red Hat Lightspeed services online in the Red Hat Hybrid Cloud Console.
  • The Insights client collects data of your hosts and Satellite forwards the data through the Insights client to the Red Hat Hybrid Cloud Console to calculate recommendations.
  • You can view and remediate those recommendations both in the Satellite web UI and in the Red Hat Hybrid Cloud Console.
  • Satellite uploads host inventory reports to the Red Hat Hybrid Cloud Console.
  • You have control over how much information is included in those reports.
  • You cannot use local Red Hat Lightspeed in Satellite.

Prerequisites

Troubleshooting

  • You can find the logs in the /var/log/foreman/production.log file.
  • If you have problems connecting to Red Hat Lightspeed, ensure that your certificates are up-to-date. Refresh your subscription manifest to update your certificates.

Link kopieren

You can configure how Satellite handles the data collected from hosts before uploading it to the Red Hat Hybrid Cloud Console and how Satellite handles hosts in the Red Hat Hybrid Cloud Console that are no longer managed by Satellite.

9.2.1. Minimizing collected data
Link kopieren

You can configure Satellite to use minimal reporting if you want to limit the data sent to Red Hat.

You can use minimal reporting to limit the amount of system data sent to the Subscriptions service, which remains active. Other Red Hat Lightspeed services are disabled because they require installed package data, which minimal reports do not include. Reports are still processed daily during the midnight synchronization cycle.

Minimal reports also exclude hostnames, IP addresses, and installed packages. Therefore, obfuscation and exclusion settings do not apply.

If you switch to Analytics data collection, Satellite enables the following settings by default:

  • Obfuscate host names
  • Obfuscate host ipv4 addresses
  • Exclude installed packages

Review and adjust these settings to control what data Satellite shares.

Prerequisites

  • Your user account has a role that grants the edit_settings permission.
  • Ensure that you delete existing data in Red Hat Lightspeed Inventory before switching to minimal reporting. To remove existing data of a system, navigate to Inventory > Systems in the Red Hat Hybrid Cloud Console, select the system, and click Delete.
  • You have selected an organization and location.

Procedure

  1. In the Satellite web UI, navigate to Red Hat Lightspeed > Inventory Upload.
  2. Select the Minimal data collection setting from the dropdown menu under Settings.
  3. When you select this option, Satellite also updates the corresponding setting on the Red Hat Lightspeed tab under Administer > Settings.
  4. Click the Generate and upload report button to create a new inventory report and send it to the Red Hat Hybrid Cloud Console.

9.2.2. Obfuscating hostnames and IP addresses
Link kopieren

You can configure Red Hat Satellite to obfuscate hostnames and IP addresses when uploading host data to Red Hat Lightspeed. Obfuscation ensures that sensitive identifying information is not exposed.

When obfuscation settings are enabled, Satellite obfuscates hostnames and IP addresses. If obfuscation settings are enabled and the host has its own insights-client obfuscation settings, Satellite honors the host settings. If obfuscation settings are disabled, Satellite does not obfuscate hostnames or IP addresses unless the client has obfuscation enabled in insights-client.

By default, Satellite applies global obfuscation settings unless an insights-client on the host overrides the settings with its own configuration.

Prerequisites

  • Your hosts have insights-client installed and configured.

Procedure

  1. In the Satellite web UI, navigate to Red Hat Lightspeed > Inventory Upload.
  2. Enable the Obfuscate host names setting to obfuscate host names sent to the Red Hat Hybrid Cloud Console.
  3. Enable the Obfuscate host ipv4 addresses setting to obfuscate IPv4 addresses sent to the Red Hat Hybrid Cloud Console.

Verification

  1. In the Satellite web UI, navigate to Red Hat Lightspeed > Inventory Upload.
  2. In the Organization dropdown menu, select the organization that uploaded the host data.
  3. Click Download report to download the host inventory report from Red Hat Lightspeed.
  4. Verify that the hostname is randomhostname.example.com and the IP address is obfuscated.

9.2.3. Removing hosts from the Red Hat Lightspeed Inventory
Link kopieren

When hosts are removed from Satellite, they can also be removed from the inventory of Red Hat Lightspeed, either automatically or manually. You can configure automatic removal of hosts from the Red Hat Lightspeed Inventory during Red Hat Hybrid Cloud Console synchronization with Satellite that occurs daily by default.

If you leave the setting disabled, you can still remove the bulk of hosts from the Inventory manually.

If Automatic mismatch deletion is enabled, Satellite removes any hosts from the Red Hat Hybrid Cloud Console that are not registered in Satellite. Enable this setting only when all hosts are registered through Satellite. If any hosts are registered through other Satellite instances or directly to the Red Hat Hybrid Cloud Console, Satellite deletes them.

Prerequisites

  • Your Satellite account has a role that grants the view_foreman_rh_cloud and edit_settings permissions.

Procedure

  1. In the Satellite web UI, navigate to Red Hat Lightspeed > Inventory Upload.
  2. Enable the Automatic mismatch deletion setting.

9.3. Deploying Insights client on registered hosts

9.7. Exclusion of hosts from Red Hat Lightspeed analytics
Link kopieren

You can exclude hosts from Red Hat Lightspeed analytics by using host parameters.

host_registration_insights
Setting this parameter to false will prevent Satellite Server from forwarding data from the Insights client on hosts to Red Hat Lightspeed services. The Insights client will not be installed on newly registered hosts.
host_registration_insights_inventory

Setting this parameter to false will exclude the host from the Satellite host inventory that is uploaded to the Red Hat Hybrid Cloud Console.

If you exclude a host that is already reported on the Red Hat Hybrid Cloud Console, it will be still removed automatically from the inventory. However, this process can take some time to complete.
