-A ServiceControl monitoring instance is more lightweight than a regular ServiceControl instance. Nevertheless, it is not recommended to host a monitoring instance on the same machine that is hosting production endpoint instances.

 ### Wire usage
 
-Each endpoint instance collects performance metrics which are buffered and then sent. A single metrics message contains a batch of values written in a compact binary format, making reporting very lightweight.
