Workflow Bridge Real-time Forwarding Agent(4.0)
- Jenni Wallin
The Workflow Bridge forwarding agent is responsible for sending data to a Workflow Bridge collection agent.
Configuration
You open the Workflow Bridge forwarding agent configuration dialog from a workflow configuration: you can right-click the agent icon and select Configuration..., or double-click the agent icon.
Workflow Bridge forwarding agent configuration dialog for a real-time workflow
| Setting | Description |
|---|---|
Profile | This is the profile to use for communication between the workflows. For information about how to configure a Workflow Bridge profile, see Section Workflow Bridge Profile Configuration. All workflows in the same workflow configuration can use separate profiles. For this to work, the profile must be set to Default in the Workflow Table tab found in the Workflow Properties dialog. For further information on the Workflow Table tab, refer to Workflow Table Tab(3.0). To select a profile, click on the button, select the profile to use, and then click . |
Transaction Behavior
For information about the general 
transaction behavior, see Workflow Monitor.
Emits
The agent emits data in the ConsumeCycleUDR and the WorkflowState UDRs.
Retrieves
The agent retrieves ConsumeCycleUDRs and ErrorCycleUDRs from the collection workflow.
Input/Output Data
The agent consumes bytearray types and any UDRs, as configured in the profile, refer to Workflow Bridge (3.0) for more information.
MIM
For information about the MIM and a list of the general MIM parameters, see Administration and Management(3.0).

MIM Parameter | Description |
Number of collectors | Number of collectors is of the int type and indicates the number of collectors configured in the Workflow Bridge profile. |
| Forwarding Queue Size | Forwarding Queue Size is of the int type and contains the value of forwardingQueueSize , which is defined under the Advanced tab in the Workflow Bridge profile configuration. |
| Forwarding Queue Utilization | Forwarding Queue Utilization is of the any type and contains a hashmap of the number of UDRs that are currently queued in the forwarding workflows. The loadId values of the collecting workflows are used as keys to the hashmap. If loadId is not used, the key will have the value 1. The hashmap is periodically refreshed and cached in order to prevent impact on performance when the MIM value is repeatedly queried. |
Example use of Forwarding Queue Utilization in APL
consume {
map<int, int> queueMap = (map<int, int>)
mimGet("Workflow_Bridge_1", "Forwarding Queue Utilization");
int loadId = 1;
int queueSize = mapGet(queueMap, loadId);
debug("Queue Utilization: " + queueSize);
wfb.ConsumeCycleUDR ccUDR = udrCreate(wfb.ConsumeCycleUDR);
ccUDR.Data = input;
udrRoute(ccUDR);
}
Accesses
The agent does not access any MIM resources.
Agent Message Events
There are no agent message events for this agent.
For information about the agent message event type, see Agent Event(3.0).
Debug Events
Debug messages are dispatched in debug mode. During execution, the messages are displayed in the Workflow Monitor.
You can configure Event Notifications that are triggered when a debug message is dispatched. For further information about the debug event type, see Debug Event(3.0).
The agent produces the following debug events:
Connected to local <Collector agent address>
This message is displayed when a connection has been established with a Collection agent.
Disconnected from <Collector agent address>
This message is displayed when a connection has been released.
Trying to connect to <Collector agent address>
This message is displayed when a forwarding agent is trying to connect to a collector.
