Chapter 10. Monitoring hosts by using Red Hat Lightspeed in Satellite

You can use local services of Red Hat Lightspeed in Satellite to assess system health on hosts running Red Hat Enterprise Linux without connecting to the Red Hat Hybrid Cloud Console. Red Hat Lightspeed in Satellite provides advisor recommendations and vulnerability reports.

If you use Red Hat Lightspeed in Satellite:

  • The Red Hat Lightspeed services run locally on your Satellite Server.
  • Satellite only communicates with the locally running services of Red Hat Lightspeed in Satellite.
  • Satellite does not send any reports to the Red Hat Hybrid Cloud Console.
  • Satellite does not forward any data through the Insights client to the Red Hat Hybrid Cloud Console.
  • You cannot use any of the hosted services on the Red Hat Hybrid Cloud Console.

Prerequisites

Troubleshooting

  • You can find the logs in the /var/log/foreman/production.log file.
