A monitoring event is an event generated by a driver, such as the LON driver, BACnet driver, Modbus driver, or IAP driver (e.g., IOX), to publish an update to a datapoint value via IAP/MQ. The driver may have received the updated value as a result of a poll request, an event-driven update from an external edge device (e.g., LON or BACnet), or an internally generated event-driven update (e.g., IOX).  For drivers that support external edge-device polling, such as LON, BACnet, and Modbus, the drivers will stop polling while monitoring is paused. For drivers that support event-driven updates, the drivers will suppress publishing the event-driven update via IAP/MQ while monitoring is paused.

You can pause/resume monitoring events in one of the following ways:

1. Using the Devices widget → Pause () and Monitor () buttons located at the top of the Devices widget.
   1.  This method is used to pause/resume all monitoring events for the entire CMS.
   2. With SmartServer IoT 2.7 or higher, the ability pause/resume monitoring events is available for the LonTalk subsystem.
   3. With Remote CMS (available with SmartServer 3.5 and higher), you can pause/resume monitoring events for all SmartServers with one action.
      
      
2.  Using the Devices widget → Segment Controllers tab → Disable / Enable Event Logging action.
   1. This method is used to pause/resume events for a specific segment controller.
      
      

You can pause/resume data logging as follows:

1. Using the Devices widget → Segment Controllers tab → Disable / Enable Data Logging action.
   1.  This method is used to pause data logging for a specific segment controller.
      
      

The sections below describe how to use these methods and consist of the following:

Pausing and Resuming All Monitoring Events for All SmartServers

To pause all monitoring events, click the Pause button () located on the Devices widget.

To resume all monitoring events, click the Monitor button () located on the Devices widget.

Setting Monitoring Event Logging and Data Logging per Segment Controller

The Devices widget, SEGMENT CONTROLLER tab provides the ability to enable/disable (functions toggle based on current state) monitoring event logging and/or data logging for specific SmartServers. These actions are enabled by default. For Remote CMS, you can enable/disable monitoring event logging and data logging for all SmartServers.

To modify the monitoring event logging and data logging settings, perform the following steps:

1. Open the SmartServer CMS.
   
   

2. Open the Devices widget, SEGMENT CONTROLLER tab. Click the Expand button (  ). 

   
   
   

3. Click the Action button () and select the Enable Data Logging action (if data logging is disabled) or the Enable Event Logging action (if event logging is disabled).
