Examples of com.jitlogic.zorka.core.perfmon.QueryDef

com.jitlogic.zorka.core.perfmon.QueryDef
JMX query object. It represents JMX query as issued by zabbix.discovery(), zorka.ls() and other components. It also defines simple DSL for querying. Query objects are immutable and persistent - modifier functions implemented by this class do not change object itself but creates (changed) copy instead. JMX query in zorka defines object name, list of attributes from object name to retain and rules for traversing object graph referenced from MBean (and storing selected attributes). Those rules are called query segments. @author rafal.lewczuk@jitlogic.com
