Allocation latency (ms)

The average time difference between when an item is taken from the allocation queue and when it is returned to the completion queue after analysis.

Completion latency (ms)

The average time difference between when an item is taken from the completion queue and when it is finished in the hub.

Completion pending items

The number of events awaiting completion acknowledgement from the source.

Input connection count

The number of client applications passing events to the hub.

Input queue pending items

The number of items in the input queue waiting to be pre-processed.

Input received items/sec

The rate at which items are being added to the hub input queue.

Input throttling

'1' if the hub is memory throttling, '2' if the hub is event count throttling, '0' if no throttling.

Item count high watermark

The maximum number of items the hub will accept before throttling or failing items.

Item count low watermark

The item count at which the hub resumes normal operation after the high watermark has been reached.

Item latency (ms)

The average time difference between when an item arrives in the input queue and when it is finally removed from the completion queue.

Items being completed

The number of items currently being completed.

Items being preprocessed

The number of items currently being preprocessed.

Items failed (throttling)

The number of items failed by throttling in 'Fail' mode - not applicable if in 'Wait' mode.

Items failed (timeout)

The number of items failed by event timeout.

Items failed (total)

The total number of items that have failed analysis.

Items processed

The number of items successfully analyzed.

Items received

The number of items passed to the hub for analysis.

Memory high watermark

The maximum data size (bytes the hub will accept before throttling or failing items).

Memory low watermark

The data size (bytes at which the hub resumes normal operation after the high watermark has been reached).

Preprocessed items/sec

The rate at which items are being pre-processed before being analyzed by a policy engine.

Total item count

The number of items in all the input queues.

Total item memory

The data size (bytes) of all the items in the hub, that is, the total memory allocated to all hub input queues. This value is the basis for the HighWaterMarkMB and LowWaterMarkMB hub registry values.
