Hi, Every "topology.builtin.metrics.bucket.size.secs," each component in my topology is sending builtin metrics to a metrics consumer (as expected). However, I am confused about some of the data that I am receiving.
For example, one DataPoint object I receive has a name of "__emit-count"
and a value (map) of {"default" : 980, "__system": 20}.
How do I figure out what the meaning of "__system" key is? or even the
meaning of "default" key.
