Hi,
As I saw in the source for the mysql plugin, the collector specifically ignors the Prepared_stmt_count variable.

Current behavior:
All the SQL activities either don't support Insert or are specific to a usecase

• Messages last minute
• Messages last hour
• Messages last 24h
• Shortest time between messages
• Min/max/average message payload size

Problem or use case

The client is currently only logging errors and warnings. For debugging purposes and during application development, it would be very useful to also have logs detailing the message flow.

Preferred solution or suggestions

TRACE level logging for incoming and outgoing MQTT control packet types, e.g., PUBLISH, SUBSCRIBE, PUBACK, SUBACK.
