Class MemorySla

java.lang.Object
  org.openspaces.admin.esm.deployment.MemorySla

All Implemented Interfaces:

SLA

public class MemorySla
extends Object
implements SLA

Memory Service Level Agreement (SLA) specifying the threshold to trigger memory breach. Threshold is breached if memory usage percentage is above or below the specified threshold.

 Disclaimer: This interface and the elastic data grid functionality is provided as a technology preview in XAP 7.1. 
 As such, it is subject to API and behavior changes in the next XAP releases without going through the usual deprecation process 
 of the XAP API.
 

Constructor Summary

MemorySla(String threshold)
An SLA with a memory threshold percentage and a default moving average subset size of 6 (Six samples five seconds apart, giving a total of a 30 seconds window).

MemorySla(String threshold, int subsetSize)
An SLA with a memory threshold percentage and a given moving average subset size (samples are five seconds apart, giving a total of a subsetSize*5 seconds window).

Method Summary

int	getSubsetSize() Returns the moving average subset size.
int	getThreshold() Returns the threshold integer value.

Constructor Detail

MemorySla

public MemorySla(String threshold)

An SLA with a memory threshold percentage and a default moving average subset size of 6 (Six samples five seconds apart, giving a total of a 30 seconds window).

Parameters:

threshold - A memory usage percentage (e.g. 75%).

MemorySla

public MemorySla(String threshold,
                 int subsetSize)
