OnQueueEvent

CFS generates events when the outgoing queue (for indexing) becomes full, becomes empty, or the queue size passes certain thresholds. This parameter specifies the name of the handler to use to handle the events.

The name that you specify must represent a section in the configuration file that contains the LibraryName parameter and any other settings for the event handler. For example:

[Indexing]
...
OnQueueEvent=MyHandler
QueueFillingThreshold=0.7
QueueEmptyingThreshold=0.4

[MyHandler]
LibraryName=LuaHandler
LuaScript=./handle_queue_event.lua

In the example above, the Lua script might respond to the events by sending a notification to an administrator.

An event contains the following information:

queueEventType The type of event, for example QueueFull or QueueFilling.
maxQueueSize The maximum size of the queue.
queueSize The current size of the queue (not present for QueueEmpty events).
Type: String
Default:  
Required: No
Configuration Section: Indexing
Example: OnQueueEvent=MyEventHandler
