Do you know what kind of error logs are sent by Hikari and how often?

Here are the logged errors I found in HikariCP:

"Property {} does not exist on target {}"
"{} - JMX name ({}) is already registered."
"{} - Failed to execute{} connection test query ({})."
"Failed to load driver class {} from HikariConfig class classloader {}"
"{} - Error thrown while acquiring connection from data source"

They appear to be entirely configuration and connection errors, so I wouldn't expect them to appear often.
