Description

Domino Domain Monitoring (DDM) collects server status and problem information in events4.nsf and ddm.nsf. In larger environments with centralized DDM roll-up, this is helpful – however, in small or single-server setups it causes overhead without being used. DDM_DISABLED=1 disables DDM on the server completely: no DDM events are generated, and no DDM probes are executed.
Classic server events (console log, log.nsf) are unaffected.

Example configuration

DDM_DISABLED=1

Notes & pitfalls

  • Assumes that DDM is not used centrally.
  • After this, server health reports and some console commands (show ddm) no longer return meaningful values.
  • Takes effect after a server restart.
  • Complementary to DDM_NoEvents_From_Lookups and EVENTS4 parameters.
  • Do not enable on large server domains – DDM is an important monitoring tool there.
