sys_attrs_kevm(5)
NAME
  sys_attrs_kevm - kevm subsystem attributes

DESCRIPTION
  This reference page lists and describes attributes for the Kernel Event
  Manager (kevm) subsystem. See sys_attrs(5) for general guidelines about
  changing system attributes. See evm(5) for more information about Event
  Manager software.

  An asterisk (*) preceding the name of an attribute in the following list
  means that the attribute can be configured at run time. Values of other
  attributes cannot be changed without rebooting the system.

  * do_reset_stats
      A value that can be used to reinitialize all of the kevm stats_*
      attributes. Changing do_reset_stats to any non-zero value causes all
      the stats_* attributes to be reset to zero, and then do_reset_stats
      itself is automatically reset to zero.

      Default value: 0

      Minimum value: 0

      Maximum value: 2,147,483,647

      If you use dxkerneltuner to change the value of do_reset_stats, the
      updated attribute values are not visible until you exit and restart
      dxkerneltuner.

  events_in_queue_count
      The number of EVM events currently queued in kernel space for
      collection by the EVM daemon.  This attribute is query only.

  evm_interrupt_buffer_size
      The size (in bytes) of the fixed buffer used to queue any EVM events
      that are posted while the kernel is executing at interrupt level.
      Events are moved out of the buffer as soon as the system returns to
      normal operating mode. The default buffer size should be adequate for
      most systems.

      Default value: 65, 536 (bytes)

      Minimum value: 1

      Maximum value: 1,844,674,407,370

  kevm_is_open
      A value that indicates whether a process (such as kevmd) currently has
      or does not have the kevm interface in an open state. The value 1 means
      that a process has the interface open (always the case if kevmd is
      running) and the value 0 means that no process has the interface open.
      This attribute is query only.

  kevm_major
      The major device number being used by the kevm interface. This
      attribute is query only.

  * stats_events_in
      The number of EVM events that have been posted in the kernel since the
      the system was started or the counter was reset.	You can reset
      stats_events_in directly, or by changing do_reset_stats to a non-zero
      value.

      Minimum value: 0

      Maximum value: 2,147,483,647

  * stats_events_read
      The number of EVM events that have been read from kernel space by the
      EVM daemon (evmd) since the system was started or the counter was
      reset.  You can reset stats_events_read manually or by changing
      do_reset_stats to a non-zero value.

      Minimum value: 0

      Maximum value: 2,147,483,647

  * stats_queue_high_watermark
      The highest number of EVM events that have been queued in kernel space
      waiting to be collected by the EVM daemon since the the system was
      started or the counter was reset.	 You can reset
      stats_queue_high_watermark manually or by changing do_reset_stats to a
      non-zero value.

      Minimum value: 0

      Maximum value: 2,147,483,647
