NAME
sys_attrs_kevm — KEVM (Kernel Event Manager) subsystem attributes
DESCRIPTION
This manpage lists and describes attributes for the Kernel Event
Manager
(kevm)
subsystem.
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 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
