NAME

IBM::StorageSystem::Statistic::ClusterReadWriteLatency - Utility class for IBM::StorageSystem cluster read and write operation latency performance data.

SYNOPSIS

IBM::StorageSystem::Statistic::ClusterReadWriteLatency is a utility class for IBM::StorageSystem cluster read and write operation latency performance data.

An IBM::StorageSystem::Statistic::ClusterReadWriteLatency object represents a collection of averaged statistical measurements for creation and deletion operation latency across all nodes in the target cluster during a single interval period.

The interval period is defined by the interval parameter passed on invocation to the specific parent class.

METHODS

start_time

The start time of the interval over which the data was collected in the format 'YYYY-MM-DD HH:MM:SS UTC+HH'.

end_time

The end time of the interval over which the data was collected in the format 'YYYY-MM-DD HH:MM:SS UTC+HH'.

avg_read_latency

The average latency of a read operation (in milliseconds/operation) across all nodes in the target cluster.

avg_write_latency

The average latency of a write operation (in milliseconds/operation) across all nodes in the target cluster.
