Description

According to the HCL product documentation (14.5.1, Disabling platform statistics):
By default, platform statistics are enabled. You can disable them using a NOTES.INI setting.
To disable platform statistics, enter this setting in the NOTES.INI file, and then restart the Domino® server: Platform_Statistics_Disabled=1
With Platform_Statistics_Disabled=1, the Domino server's collection and evaluation of platform statistics is fully turned off. Platform statistics provide metrics about CPU usage, memory consumption, disk I/O, and network throughput — visible in the show stat platform console output and in the corresponding statistics documents in events4.nsf / statrep.nsf.
Typical use cases for disabling:
  • External monitoring solutions (Nagios, Prometheus, Datadog, AppDynamics) already provide the same data and Domino's own sampling should be avoided.
  • On Linux systems where the Domino service user has no read rights on /proc — sampling there fails repeatedly otherwise.
  • On very performance-constrained test/lab servers, where statistics sampling unnecessarily consumes resources.

Example configuration

Disable platform statistics:
Platform_Statistics_Disabled=1
Enable platform statistics — default, omit the parameter:
# Platform_Statistics_Disabled=0

Notes & pitfalls

  • A change requires a server restart so that the statistics sampler thread is reconfigured.
  • HCL explicitly names the switch as Platform_Statistics_Disabled (negative logic) — a "Platform_Statistics_Enabled" parameter does not exist in the HCL docs.
  • On Linux, the Domino service user requires read rights on /proc and /proc/<pid> — without these rights, platform statistics are effectively empty, and the switch is then only cosmetic.
  • Cross-platform note: on Windows, sampling provides performance counter data via WMI/PDH; the Linux /proc issues do not occur there.
  • For detailed tracing, the switch works together with Stats_Cluster and Show Stat console commands.
