The status panel is split into 2 main sections. The
top section shows real time graphs representing the
events pushed and popped from the queue, both in terms
of rates (i.e. per status interval) as well as the totals.
The bottom section shows the actual values plotted
in the graphs for events pushed and popped, as well
as information about the actual queue store at the server.
The image below shows the status panel for an active
cluster queue.
The top most graph in the panel shows the event history
for events popped from the queue. The red line graphs
the rates at which events are being popped while the
yellow line graphs the total events popped from the
queue.
The bottom graph shows the event history for events
pushed onto the queue. The red line graphs the rates
at which events are being pushed while the yellow line
graphs the total events pushed to the queue. As the
status events are consumed, and the queue (nLeafNode)
is updated with the new values for events popped and
pushed, the status panel and its graphs will be updated.
The bottom section of the status panel shows 3 types
of information : Totals, Rates and Event Store. These
are discussed below.
Totals
The totals section shows 5 values:
Published - The total number of
events pushed to the queue when the last status event
was consumed
Consumed - The total number of events
popped from the queue when the last status event was
consumed
Event ID - The event id of the last
event pushed to the queue
Current Conections - The current
number of asychronous consumers on the queue
Total Connections - Total number
of asychronous consumers that have subscribed to the
queue
Rates
The rates section shows 3 values:
Published - The current rate of
events pushed to the queue, calculated as (total -
previous total) / (interval 1000 millseconds)
Consumed - The current rate of events
popped from the queue, calculated as (total - previous
total) / (interval 1000 millseconds)
Conections - The current rate of
asynchronous subscriptions being made to the queue
Event Store
The event store section shows 4 values:
Used Space - The amount of space
in KB used by the queue on the server (either memory,
or disk for persistent / mixed queues)
Events - The current number of events
on the queue
% Free - The amount of free space
in the queue store (calculated as (used space - (total
space used by all purged or aged events))
Cache Hit - The %age of events popped
from the queue event cache as opposed form the actual
physical store if persistent or mixed
