Enable IO Logging

Associated with: MQTT Sparkplug™ B Broker items

Security permission required to access this pick action: Diagnostics

Used this pick action to enable I/O logging on an MQTT Sparkplug B Broker item in the database. When enabled, Geo SCADA Expert logs the communications that occur on the Broker, including any data that is discarded by the driver.

IO Logging on a Broker is not enabled by default. Before enabling such logging, ensure that enough disk space is available to store the log files that will be produced.

Select the Enable IO Logging pick action to display the Enable IO Logging dialog box.

Either:

• Select the Persist check box to set IO logging so that it remains enabled until it is explicitly disabled. IO logging will remain enabled even after the driver stops or a changeover occurs.
• Clear the Persist check box to temporarily enable IO logging on this MQTT Sparkplug B Broker item - the IO logging is enabled but will end when the driver stops or a changeover occurs.

Select the OK button to enable I/O logging on the MQTT Sparkplug B Broker item.

I/O logging on MQTT Sparkplug B Broker items works in a similar way to I/O logging on channels on other drivers. For more information, see Enable or Disable I/O Logging on a Channel in the Geo SCADA Expert Guide to Server Administration.
