File audit logging and watch folders

File Audit Logging (FAL) and Watch Folders use message queues in order to monitor file access on the cluster.

FAL producers create messages when certain file operations are performed (for example, file writes, reads, and so on). FAL consumers read these messages and perform required actions, such as writing to audit logs. All nodes, including the nodes providing IBM Storage Scale Erasure Code Edition storage may be producers, in order to provide complete access logging. Consumers must be on nodes that do not provide storage to IBM Storage Scale Erasure Code Edition cluster, due to the additional load on the system caused by monitoring usage on the cluster. In addition, consumer nodes should not run real-time or time-sensitive applications.
