The PI_LDA record stores the performance data indicating the values summarizing the execution status of read and write operations on the logical devices for each storage system.

Note: If the logical devices were excluded from the monitoring targets during the setup of the RAID Agent instance environment, information about those logical devices will not be applied to this record.

Collection Interval

300

Key Field

None

Lifetime

From when the instance is created to when it is deleted

Fields

Field Name	Description	Access Type	Format
INPUT_RECORD_TYPE	Record type identifier, which is always set to LDA.	1, 2, 3, 4	string(8)
INTERVAL	Interval (in seconds) at which information is collected.	1, 2, 3, 4	ulong
LDEV_COUNT	Total number of logical devices that can be monitored by the RAID Agent. A LUSE is counted as one logical device.	1, 2	ulong
MONITORED_LDEV_COUNT	Number of logical devices currently monitored by the RAID Agent. If the logical devices to be monitored are specified in the logical device definition file (ldev_filter.ini), the number of those logical devices is stored in this field. Note that a LUSE is counted as one logical device.	1, 2	ulong
READ_HIT_IO_COUNT	Number of times the cache is hit for read operations.	1, 2	double
READ_HIT_RATE	Cache hit rate of read operations. The value is calculated based on the following formula: (READ_HIT_IO_COUNT / READ_IO_COUNT) * 100	1, 2	double
READ_IO_COUNT	Number of read operations.	1, 2	double
READ_IO_RATE	Frequency of read operations (number of times per second). The value is calculated based on the following formula: READ_IO_COUNT / INTERVAL	1, 2, 3, 4	double
READ_MBYTES^*	Read data transfer size (MB).	1, 2	double
READ_RESPONSE_RATE	This field cannot be used because it is reserved.	--	--
READ_TOTAL_RESPONSE	This field cannot be used because it is reserved.	--	--
READ_XFER_RATE^*	Read transfer speed (MB per second). The value is calculated based on the following formula: READ_MBYTES / INTERVAL	1, 2, 3, 4	double
RECORD_TIME	Time (in GMT) at which data was collected from the storage system and the record was created.	1, 2, 3, 4	time_t
WRITE_HIT_IO_COUNT	Number of times the cache is hit for write operations.	1, 2	double
WRITE_HIT_RATE	Cache hit rate of write operations. The value is calculated based on the following formula: (WRITE_HIT_IO_COUNT / WRITE_IO_COUNT) * 100	1, 2	double
WRITE_IO_COUNT	Number of write operations.	1, 2	double
WRITE_IO_RATE	Frequency of write operations (number of times per second). The value is calculated based on the following formula: WRITE_IO_COUNT / INTERVAL	1, 2, 3, 4	double
WRITE_MBYTES^*	Write data transfer size (MB).	1, 2	double
WRITE_RESPONSE_RATE	This field cannot be used because it is reserved.	--	--
WRITE_TOTAL_RESPONSE	This field cannot be used because it is reserved.	--	--
WRITE_XFER_RATE^*	Write transfer speed (number of MB per second). The value is calculated based on the following formula: WRITE_MBYTES / INTERVAL	1, 2, 3, 4	double
* For logical devices for which the mainframe emulation type is set, this value can be collected only when the storage system is VSP 5000 series, VSP G1000 (80-03 or later), G1500, or VSP F1500.
