Table 22. 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 to 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 to 100.
bytes-per-second string The data transfer rate, in bytes 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.
bytes-per-second-numeric uint64 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 restarted.
