> Key: TINKERPOP-2471
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2471
> Project: TinkerPop
> Issue Type: Improvement
> Components: dotnet
> Reporter: Florian Hockmann
> Priority: Minor
>
> It would be helpful to have logging in the driver to get insights into its
> internal state. Examples for events that we could log are:
> * A connection is dead & will be replaced.
> * The pool is empty, so we cannot get a connection for the current request
> (but will probably try again)
> This should make it more transparent for users how the driver operates and
> what its current state is.
