TPS

Last Updated：2023-08-15 11:20:59 Updated

This topic describes the performance metric TPS within an OceanBase Database tenant. TPS indicates the number of transactions processed per second in an OceanBase Database tenant. TPS consists of the following two sub-metrics: transaction_single_partition_count that indicates the number of general transactions processed per second, and transaction_multi_partition_count that indicates the number of distributed transactions processed per second in a tenant. You can specify a statistical period to query statistics about the TPS metric in a single zone or on a single OBServer of an OceanBase Database tenant.

transaction_single_partition_count

Definition

The number of general transactions processed per second in an OceanBase Database tenant.

Metric

Metric	Metric name	Unit
transaction_single_partition_count	transaction_single_partition_count	N/A

Calculation expression

sum(rate(ob_sysstat{stat_id="30012",@LABELS}[@INTERVAL])) by (@GBLABELS)

transaction_multi_partition_count

Definition

The number of distributed transactions processed per second in an OceanBase Database tenant.

Metric

Metric	Metric name	Unit
transaction_multi_partition_count	transaction_multi_partition_count	N/A
