Structure that holds statistics for an event queue.
This structure holds statistics for messages and other events that enter and exit the event queue. NOTE: Specific count-enable options must sometimes be enabled for these statistics to populate.
Note that when stats are sampled, the fields in the structure are not necessarily from the same instant in time. The structure might be updated concurrently with it being sampled, and while each structure field is atomically read, the field values can be skewed slightly across time.
See lbm_event_queue_stats_t_stct for field definitions.
Cumulative vs Sample
Most UM statistics are cumulative. For example, tr_dgrams_sent starts at zero and grows over time as more and more topic resolution datagrams are sent.
But some statistics are samples, meaning that they represent the value at a moment in time. These values can go up and down. For example, tr_src_topics indicates the number of sources at the time of the sample.
