Functions ¶

func InitMetrics ¶

func InitMetrics(namespace, subsystem string)

InitMetrics initializes metrics variables with given namespace and subsystem name.

func ObserveReadSLI ¶

func ObserveReadSLI(readKeys uint64, readTime float64, readSize float64)

ObserveReadSLI observes the read SLI metric.

func RegisterMetrics ¶

func RegisterMetrics()

RegisterMetrics registers all metrics variables. Note: to change default namespace and subsystem name, call `InitMetrics` before registering.

Types ¶

type TxnCommitCounter ¶

type TxnCommitCounter struct {
	TwoPC       int64 `json:"twoPC"`
	AsyncCommit int64 `json:"asyncCommit"`
	OnePC       int64 `json:"onePC"`
}

TxnCommitCounter is the counter of transactions committed with different protocols, i.e. 2PC, async-commit, 1PC.

func GetTxnCommitCounter ¶

func GetTxnCommitCounter() TxnCommitCounter

GetTxnCommitCounter gets the TxnCommitCounter.

func (TxnCommitCounter) Sub ¶

func (c TxnCommitCounter) Sub(rhs TxnCommitCounter) TxnCommitCounter

Sub returns the difference of two counters.
