Class AlarmMemcachedClient

java.lang.Object

com.solab.alarms.AlarmMemcachedClient

All Implemented Interfaces:

AlarmCache

public class AlarmMemcachedClient
extends Object
implements AlarmCache

An alarm cache that uses memcached to store the data it needs to know if an alarm message should be resent. This is useful in environments where you have several applications which can be using similar alarm channels, since the DefaultAlarmCache is internal to the app and events in two or more apps will cause an alarm to be sent from each app.
