sys_attrs_kevm - kevm subsystem attributes
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 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 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. 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
