Changed Features

Persistent connection statistics

The output of show servers now shows the number of times a connection was taken from a server's pool as well as the ratio of connections taken from the pool versus newly created connections.


When known, the session id will be included in all logged messages. This allows a range of logged messages related to a particular session (that is, client) to be bound together, and makes it easier to investigate problems. In practice this is visible so that if a logged message earlier looked like

2017-08-30 12:20:49   warning: [masking] The rule ...

it will now look like

2017-08-30 12:20:49   warning: (4711) [masking] The rule ...

where 4711 is the session id.
