Previously, reverting pending changes did not revert global settings that require a full site restart. Worse, reverting such a change could stop site services like the web server without starting them again, leaving the site unreachable. Both issues are now fixed.

The affected settings are:

  • Start during system boot
  • Monitoring core
  • Access to Livestatus via TCP
  • Start Livestatus proxy
  • Event Console
  • Enable piggyback-hub
  • Send traces from Checkmk
  • Receive traces
  • Enable OpenTelemetry Collector

The exact set you see depends on your edition.

Note: While the reverted configuration is being applied, the page does not yet update on its own. Reload it to see the current status.
