Encrypted Volume and File System v2.2 Administrator Guide (777846-001, April 2014)

Syntax
evfsadm stat [-a|-s|-z]
where:
-a Displays all available information about EVFS. Displays the number of EVFS volumes, the
EVFS subsystem status (up or down), and the number of kernel encryption threads. For each
EVFS volume, displays the state, as maintained by the EVFS kernel driver (enabled, disabled,
or raw) and I/O and cryptography statistics.
-s Displays EVFS encryption and decryption statistics. The evfsadm utility displays the total
number of decrypted blocks and the total number of encrypted blocks for the EVFS subsystem.
-z Resets all statistic values to zero.
Examples
The following listing shows output from the evfsadm stat -a command:
# evfadm stat -a
----- EVFS statistics -----
Total EVFS Volumes: 1
EVFS Subsystem Status: up
Active Encryption Threads: 2
---- EVFS Volume Name ----|--- State ---|---------------- Queues -------------|
orr owr odr oer
/dev/evfs/vg01/lvol5 enabled 0 0 0 0
---- EVFS Volume Name ----|--- State ---|-------------- Counters -------------|
bpr bpw bpd bpe
/dev/evfs/vg01/lvol5 enabled 2074 52441 362 52345
---- EVFS Volume Name ----|--- State ---|---------------- Rates --------------|

The meaning of each field is as follows:
Number of EVFS volumes in the kernel registry.Total EVFS Volumes
Status of the EVFS kernel components (up or down).EVFS Subsystem Status
Number of EVFS kernel threads for cryptography processing.Active Encryption Threads
Name of the EVFS volume.EVFS Volume Name
State of the EVFS volume (enabled or disabled).State
Number of queued (outstanding) read requests.orr
Number of outstanding write requests.owr
Number of outstanding decryption requests.odr
Number of outstanding encryption requests.oer
Number of data blocks read.bpr
Number of data blocks written.bpw
Number of data blocks decrypted.bpd
Number of data blocks encrypted.bpe
Read rate in kilobytes per second (kb/s). This statistic is based on the time it
takes the EVFS pseudo-driver to complete a read request. This statistic includes
kbpsr
the time it takes to read data from the physical disk and the underlying LVM or
VxVM volume (if applicable), and to decrypt the data.
Write rate in kilobytes per second (kb/s). This statistic is based on the time it
takes the EVFS pseudo-driver to complete a write request. This statistic includes
kbpsw
the time it takes to encrypt the data, and write the data to the underlying LVM
or VxVM volume (if applicable) and the physical disk.
