Description

Log_Connections=1 writes every NRPC connection setup and teardown to log.nsf. This makes it possible to reconstruct questions such as “which server mates did this server actually reach?” or “how long does a typical replication session take?”.
For servers with very many short sessions (mail servers with tens of thousands of Notes Clients), the log volume can become considerable – in that case, enable it only selectively during diagnostic windows.

Example configuration

Log_Connections=1

Notes & pitfalls

  • Log volume can grow significantly on large servers – take retention of log.nsf into account.
  • The Configuration document overrides this notes.ini setting.
  • Pairs with Log_MailRouting, Log_Sessions, and Log_Tasks for the full picture.
  • For SSL/TLS sessions, additionally consider DEBUG_TLS.
  • The change takes effect after a restart or via a set config reload.
