API Call on alarm trigger

I've had a go at getting it working based on the thread:

How to trigger a gateway timer to trigger immediately but no more than four times per minute?

I have a gateway timer script that is configured to run every 15 seconds. ds = system.tag.read("[default]Queue").value if ds.getRowCount() > 0: # Get value from queue message = ds.getValueAt(0, "message") # Complete some arbitrary stuff specialFunctions.myFunction(message) # Delete value from dataset new_ds = system.dataset.deleteRow(ds, 0) # Write new dataset back to queue system.tag.write("[default]Queue", new_ds) I have up to 100 tags feeding a queue. The purpose of the gateway t…

I had some issues where my .offer didn't seem to actually append anything to my queue.

I made a project library script called alarmQueue:

from java.util.concurrent import LinkedBlockingDeque, TimeUnit
logger = system.util.getLogger("Alarm Event Queue")
# Capacity = 100.  The new instance is thrown away if already in globals.

deque = system.util.getGlobals().setdefault('MyAlarmQueue', LinkedBlockingDeque(100))

def someTimerEvent():
	nextItem = deque.poll(15000, TimeUnit.MILLISECONDS)
	#logger.info(str(system.util.getGlobals()))
	if nextItem:
		pass
		
# Run the above at a fixed **rate** matching the poll timeout.

def addDeque(message):
	response = deque.offer(str(message))
	logger.warn(str(response))

I call the someTimerEvent() every 15000 ms in a timer script (using dedicated thread, fixed rate), I added the addDeque to the alarm active script on a a testing tag, with the below script:

	path = str(alarmEvent.getDisplayPath())
	
	AlarmQueue.addDeque(path)

The response value always returns a True, but whenever I try querying the queue using:
print AlarmQueue.Deque is just returns single value even though I trigger my alarm several times. They also dissapear after some time, does this timer event erase the queue?

Where am I getting it wrong? Or is it okay, I just don't know how to get the data back out of it
