Table 20 controller-statistics properties
Name Type Description
durable-id string • controller a
• controller b
cpu-load uint32 Percentage of time the CPU is busy, from 0–100.
power-on-time uint32 Number of seconds since the controller was restarted.
write-cache-
used
uint32 Percentage of write cache in use, from 0–100.
bytes-per-
second
string Data transfer rate calculated over the interval since these statistics were last
requested or reset. This value will be zero if it has not been requested or reset
since a controller restart.
bytes-per-
second-numeric
string Unformatted bytes-per-second value.
iops uint32 Input/output operations per second, calculated over the interval since these
statistics were last requested or reset. This value will be zero if it has not been
requested or reset since a controller restart.
number-of-reads uint64 For the controller whose host ports had I/O activity, the number of read
operations since these statistics were last reset or since the controller was
restarted.
read-cache-hits uint64 For the controller that owns the volume, the number of times the block to be read
is found in cache.
read-cache-
misses
uint64 For the controller that owns the volume, the number of times the block to be read
is not found in cache.
number-of-
writes
uint64 For the controller whose host ports had I/O activity, the number of write
operations since these statistics were last reset or since the controller was
