Statistic Names

Every name the built-in statistics publish, at each level, generated by running the statistics in the code. Statistics explains the levels and how each value is computed. Each level publishes the names of the levels before it, and the new ones listed under it. <sim_id> is the simulation's id, <name> a resource, store or container, <task> a task, and <arrival> the arrival that started a flow's entities.

none

Publishes nothing: the statistics are off.

minimal

Name	Measures
<sim_id>.stats.resources.<name>.capacity	units now
<sim_id>.stats.resources.<name>.in_use	units held by tasks; above capacity after a drop, until they finish
<sim_id>.stats.resources.<name>.queue_length	requests waiting now
<sim_id>.stats.resources.<name>.utilization	in_use as a percentage of capacity, now
<sim_id>.stats.resources.<name>.down	1 while a resource with a breakdown is down, 0 otherwise
<sim_id>.stats.stores.<name>.capacity	items it can hold now
<sim_id>.stats.stores.<name>.level	items held now
<sim_id>.stats.stores.<name>.getters_waiting	tasks waiting to get an item
<sim_id>.stats.stores.<name>.putters_waiting	tasks waiting to put an item
<sim_id>.stats.containers.<name>.capacity	largest amount, now
<sim_id>.stats.containers.<name>.level	amount held now
<sim_id>.stats.containers.<name>.getters_waiting	tasks waiting to take an amount
<sim_id>.stats.containers.<name>.putters_waiting	tasks waiting to add an amount
<sim_id>.stats.tasks.<task>.in_progress	instances queued or started and not yet ended, now

basic

Name	Measures
<sim_id>.stats.resources.<name>.utilization_avg	utilisation averaged over time, in percent
<sim_id>.stats.resources.<name>.queue_length_avg	requests waiting, averaged over time
<sim_id>.stats.resources.<name>.downtime	seconds a resource with a breakdown has been down so far
<sim_id>.stats.resources.<name>.failures	failures of a resource with a breakdown so far
<sim_id>.stats.stores.<name>.level_avg	items held, averaged over time
<sim_id>.stats.containers.<name>.level_avg	amount held, averaged over time
<sim_id>.stats.tasks.<task>.finished	instances finished so far
<sim_id>.stats.tasks.<task>.balked	instances that refused to join the queue; published once one does
<sim_id>.stats.tasks.<task>.reneged	instances that left the queue before they were served; published once one does
<sim_id>.stats.tasks.<task>.failed	instances that failed: their fail held, their function raised or their wait failed; published once one does
<sim_id>.stats.tasks.<task>.interrupted	interrupts delivered to instances, preemptions not included; published once one is
<sim_id>.stats.tasks.<task>.preempted	times a higher-priority request took an instance's unit; published once one does
<sim_id>.stats.tasks.<task>.resumed	times an interrupted instance got its units back and was served again; published once one does
<sim_id>.stats.flows.<arrival>.finished	entities that left the model, by the arrival that started them
<sim_id>.stats.flows.<arrival>.started	entities whose first task has started, by the arrival that started them
<sim_id>.stats.flows.<arrival>.in_system	entities in the model now: started, and not yet finished, failed or gone
<sim_id>.stats.flows.<arrival>.failed	entities whose flow ended in a failure no on_fail handled; published once one does

typical

Name	Measures
<sim_id>.stats.tasks.<task>.wait_mean	mean time from queued to started
<sim_id>.stats.tasks.<task>.wait_max	longest time from queued to started
<sim_id>.stats.tasks.<task>.service_mean	mean time from started to finished
<sim_id>.stats.tasks.<task>.service_max	longest time from started to finished

all

Name	Measures
<sim_id>.stats.tasks.<task>.wait_p50	median wait
