Allocation queue pending items

The number of items in the queue waiting to be allocated to a policy engine.

Byte limit (higher)

The maximum size of message events that can be processed by the current queue. This value is the basis for the MaxSizeBytes hub registry value.

Byte limit (lower)

The minimum size of message events that can be processed by the current queue. If the hub only supports a single (default) queue, this lower limit is zero bytes; if multiple queues are defined, the lower limit is always zero bytes for the smallest size queue.

Configured active engines

The number of configured active policy engines available to this queue.

Configured standby engines

The number of configured standby policy engines available to this queue.

Connected active engines

The number of active policy engines with which a connection has been established and available to this queue.

Connected standby engines

The number of standby policy engines with which a connection has been established and available to this queue.

Failure Mode

A Boolean value specifying whether the queue is currently rejecting new events because there have been no connected PEs for more than a configured period of time.

Items failed (timeout)

The number of items failed by event timeout.

Items received

The number of items passed to the queue for analysis.

Items received (supplemental)

The total number of items poached from other queues by the policy engines assigned to the current queue.

Processed items/sec

The rate at which items are being passed to the queue.
