Configuring Tracer and application restarts on hosts

If Tracer is available for your hosts, you can see which services need restarts after package updates and restart them when you choose.

Configuring Tracer on a host

You can install Tracer on hosts and access Traces on orcharhino. Tracer displays a list of outdated services and applications that need to be restarted, as well as asks you to restart the host after, for example, a kernel update. Traces is the output generated by Tracer in the orcharhino management UI.

Prerequisites

  • The host is registered to orcharhino.

  • orcharhino Client for AlmaLinux repository for the operating system version of the host is synchronized on orcharhino Server, available in the content view and the lifecycle environment of the host, and enabled for the host.

  • Remote execution is enabled.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > All Hosts.

  2. Select your host.

  3. On the Traces tab, click Enable Traces.

  4. Select the provider to install katello-host-tools-tracer from the list.

  5. Click Enable Tracer. You get a REX job notification after the remote execution job is complete.

  6. If you get a list of applications that need to be restarted, select the ones that you want to restart.

  7. Click Restart app, then click one of these buttons:

    • Restart via remote execution

    • Restart via customized remote execution

      The first option restarts the application immediately, while the second one allows you to examine and customize the REX job.

Restarting applications on a host

You can restart applications on a host from the orcharhino management UI when the host reports pending restarts, for example after package updates. orcharhino uses remote execution to restart applications on the host.

Procedure

  1. In the orcharhino management UI, navigate to Hosts > All Hosts.

  2. Click the name of the host you want to modify.

  3. Select the Traces tab.

  4. Select applications that you want to restart.

  5. Select Restart via remote execution from the Restart app list. You will get a REX job notification once the remote execution job is complete.
