Do you have any more of the stack trace of the IllegalArgumentException? It is really hard to tell what might be happening for just the small bit you have put in the e-mail. Also what version of storm are you using?

We are trying to enable export of Storm metrics using the included "LoggingMetricsConsumer" class, and we are getting errors in the worker logs: "java.lang. IllegalArgumentException: Tuple created with wrong number of fields. Expected 3 fields but got 2 fields" There are never any metrics written to the worker.log.metrics files. When that metrics consumer class is disabled in the storm yaml, the errors don't occur. We aren't using any custom metrics or anything else related. Is there something we're missing to enable writing of Storm metrics? Thank you, Karl
