Monitoring and Pausing Events and Data Logging

There are two ways to pause events:

  1. Using the Devices widget → Monitor / Pause button
    • This method is used to pause all events for the entire CMS.

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

There is one way to pause data logging:

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

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

Monitoring and Pausing All Events for Every SmartServers

With SmartServer IoT 2.7 or higher, the ability pause/monitor events is available for the LonTalk subsystem with the Pause () and Monitor () buttons located at the top of the Devices widget. 

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.

With Remote CMS (available with SmartServer 3.5 and higher), you can pause and resume events using the Pause () and Monitor () buttons for all SmartServers with one action.

To pause all monitoring events, click the Pause button ().


To resume all monitoring events, click the Monitor button ().

Setting Data and Event Logging per Segment Controller

The Devices widget, SEGMENT CONTROLLER tab provides the ability to enable or disable (enable/disable functions toggle based on current state) data and/or event logging for specific SmartServers. 

With Remote CMS, you can enable/disable datapoints and events logging for all SmartServers.

To modify the logging settings, perform the following steps:

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



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

    Disable Data Logging and Disable Event Logging actions are enabled by default.
