Setting the destination queue size

Follow these steps to increase the WebSphere® Business Monitor destination queue size.

You may need to increase the maximum size of the destination queue that receives the events messages from the event bus used by the Monitor Server. The need for this is to avoid any event loss in case the Monitor Server application is stopped or events consumption is blocked due to any runtime exceptions, and thus the events messages are not consumed from the bus destination queue so that the queue will be filled of messages and any incoming event message will not be saved in the queue. Also this situation will happen if the rate of the incoming messages is significantly grater than the rate of the message consumption by the Monitor Server, and consequently the queue may get full of messages and event loss will occur.

In order to increase the WebSphere Business Monitor destination queue size:

  1. From the WebSphere Application Server administrative console's navigation tree, select Service Integration > Busses
  2. From the Busses table, select the bus named MONITOR.<Cell_Name>.Bus, where the <Cell_Name> is the name of the cell on which the Monitor Server is installed.
  3. From the Additional Properties links, click the Destination link.
  4. From the Destinations table, select Monitor_Bus_Queue_Destination.
  5. From the Message points links, click the Queue points link.
  6. From the Queue points table select Monitor_Bus_Queue_Destination@<Node_Name>.<Server_Name>- MONITOR.<Cell_Name>.Bus
  7. In the High message threshold field, type the value of the maximum queue size you want to use. The default value is 50000 messages.
  8. Click OK.
  9. In the Message information box, click Save to apply your changes. The Save page appears.
  10. Click Save.
