APM IIB agent: What is the meaning of FAD_Level attribute in Broker_Status Dataset?

Question & Answer


Question

The IBM Integration Bus (IIB) agent contains FAD Level attribute in Broker Status dataset. This attribute is being used in predefined threshold below:
WMB_Broker_QMgr_Not_Connected
*IF *VALUE Broker_Status.Queue_Manager_Connection_Status *NE 1 *AND *VALUE Broker_Status.FAD_Level *LT 8
What does FAD_Level attribute represent and why is this threshold checking for FAD Level less than 8?

Cause

The IIB agent Reference guide shows following description of FAD Level attribute, but it does not provide details of what the FAD level attribute represents and valid values it can hold.
FAD Level
The level of format and data of current component. If two versions of the component have the same FAD level, all the database tables, command-line arguments, and some other aspects must be compatible.

Answer

The FAD Level attribute represents the version of IBM Integration Bus (IIB) node. The FAD Level value for IIB V10 is 8.
Prior to IIB V10 (FAD_Level < 8) , the broker (IIB node) was required to run with an MQ Queue Manager. In IIB V10 and higher levels (FAD_Level >= 8), the Integration Bus node can run without a Queue Manager.
The WMB_Broker_QMgr_Not_Connected threshold uses FAD Level (< 8) condition to check if the broker is at level lower than IIB V10. If broker is at a level lower than IIB V10, and the Queue Manager is not running (Queue_Manager_Connection_Status attribute), then an event is triggered.

Note: Prior releases of IBM Integration Bus (IIB) were known as WebSphere Message Broker (WMB). The latest release of the IIB product (released after IIB V10) is known App Connect Enterprise or ACE.
