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. 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. The number of EVM events currently
queued in kernel space for collection by the EVM daemon. This
attribute is query only. The size (in bytes) of the fixed buf‐
fer used to queue any EVM events that are posted while the ker‐
nel 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 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 run‐
ning) and the value 0 means that no process has the interface
open. This attribute is query only. The major device number
being used by the kevm interface. This attribute is query only.
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 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 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
