How to gather statistics from each node?

Hi,

I want to gather statistics like number of records(in and out), number of duplicate records etc., when data is ran through any Node, like DATA_READER or MERGE_JOIN… how do I do that?

Thanks,

Clover engine offers such statistics through JMX protocol. Upon graph start, an JMX MBean is created which can be queried for that.

When graph is finished, each Phase contains TrackingInfo for individual nodes belonging to tha phase.

See org.jetel.graph.runtime.jmx package.

Thanks!
