Using kstat to DetermineCryptographic Activity
The Sun Crypto Accelerator 4000 boarddoes not contain lights or other indicators to
reflect cryptographic activity on the board. Todetermine whether cryptographic
work requests are actually being performed on the board, use the kstat(1M)
command to display the device usage:
Note – In the previous example, 0is the instance number of the vca device. This
number should reflect the instance number of the board for which you are
performing the kstat command.
Displaying the kstat information indicates whether cryptographic requests or
“jobs” are being sent to the Sun Crypto Accelerator 4000 board. A change in the jobs
valuesover time indicates that the board is accelerating cryptographic work requests
sent to the Sun Crypto Accelerator 4000 board. If cryptographic work requests are
not being sent to the board, verify your web server configuration per the web server
specific configuration.
Do not attempt to interpret the kernel/driver statistic values returned by
kstat(1M). These values aremaintained within the driver to facilitate field support.
The meanings and actual names may change over time.
