Public Member Functions
std::list< DCDB::SensorDataStoreReading >	query (DCDB::Connection *connection, uint64_t start, uint64_t end)
	This function is used to query the telemetry data from the DCDB.

Public Attributes
const std::string	id
	The unique ID to identify the telemetry.
const std::string	unit
	The unit of an telemetry variable, e.g., Kelvin for temperature.
const std::chrono::duration< float >	sampling_rate {}
	float The samples per second of an telemetry.

Detailed Description

The implementation of the encapsulated type QDMI_TelemetrySensor on the device-side.

Implemented to hold all the required input to query a QDMI_TelemetrySensor using DCDB and its output. In this device, the QDMI_TelemetrySensors corresponses to the sensors at the HPC Telemetry located at the LRZ.

Note

QDMI_Device_Telemetry_Query is encapsulated in the QDMI Device Telemetry Query interface to allow the device implement the type as needed.

query()

std::list< DCDB::SensorDataStoreReading > DCDB_QDMI_TelemetrySensor_impl_t::query	(	DCDB::Connection *	connection,
		uint64_t	start,
		uint64_t	end )

This function is used to query the telemetry data from the DCDB.

This function queries telemetryal data in a given time interval using DCDB's sensor interface.

Parameters

[in]	connection	The connection object that used to connect DCDB host.
[in]	start	The start time as an UNIX timestamp of the time interval
[in]	end	The end time as an UNIX timestamp of the time interval

Returns

The reading from the given sensor within the siven time intervals
