Description
i am running a test on a streams application and gathering jmx measurements to determine what is causing some lag. using `kafka.tools.JmxTool` i was gathering the following attributes `'io-ratio', 'io-wait-ratio', 'select-rate', 'batch-size-avg', 'compression-rate-avg', 'record-size-avg', 'records-per-request-avg'` on my streams instances producers. i noticed that i was getting `io-wait-ratio > 1`, but according to docs it is "The fraction of time the I/O thread spent waiting."
some example lines from jmxtool
