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 attri-
bute 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 dae-
mon. 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 sys-
tems.
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 col-
lected 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.
