### Kubectl output verbosity and debugging
Kubectl verbosity is controlled with the `-v` or `--v` flags followed by an integer representing the log level. General Kubernetes logging conventions and the associated log levels are described [here](https://github.com/kubernetes/community/blob/master/contributors/devel/logging.md).
Verbosity | Description
--------------| -----------
`--v=0` | Generally useful for this to ALWAYS be visible to an operator.
`--v=1` | A reasonable default log level if you don't want verbosity.
`--v=2` | Useful steady state information about the service and important log messages that may correlate to significant changes in the system. This is the recommended default log level for most systems.
`--v=3` | Extended information about changes.
`--v=4` | Debug level verbosity.
`--v=6` | Display requested resources.
`--v=7` | Display HTTP request headers.
`--v=8` | Display HTTP request contents.
