Detailed Documentation

These APIs are for statistics. The data type is uint64_t for the APIs, the value should be divided by scale to get the real value for float or double data types. The unit of all utilization metrics types (including EU status and memory bandwidth) is percentage. The unit of power is W. The unit of energy is mJ. The unit of frequency is MHz. The unit of temperature is Celsius Degree. The unit of memory is Byte. The unit of memory read/write and link throughput is kB/s. All the RAS metrics types are numbers.

Get statistics data (not including per engine utilization & fabric throughput) by device.

Support Platform: Linux

Parameters:

deviceId	IN: Device id
dataList	OUT: The arry to store statistics data for device deviceId. First pass NULL to query statistics data count. Then pass array with desired length to store statistics data.
count	IN/OUT: When dataList is NULL, count will be filled with the number of available entries, and return. When dataList is not NULL, count denotes the length of dataList, count should be equal to or larger than the number of available entries, when return, the count will store real number of entries returned by dataList
begin	OUT: Timestamp in milliseconds, the time when aggregation starts
end	OUT: Timestamp in milliseconds, the time when aggregation ends
sessionId	IN: Statistics session id. Currently XPUM only supports two statistic sessions, their session ids are 0 and 1 respectively.

Returns:

xpum_result_t

XPUM_OK if query successfully
XPUM_BUFFER_TOO_SMALL if count is smaller than needed

Get engine statistics data by device.

Support Platform: Linux

Parameters:

deviceId	IN: Device id
dataList	OUT: The arry to store statistics data for device deviceId.
