flushNow([options]) ⇒ void

This will force a flush of cached event objects.

Param	Type	Description
[options]	Object	Options passed through to each queue's flush method
[options.unload]	boolean	signals the page is unloading; drains the send queue using sendBeacon or sync XHR for reliable last-chance delivery
[options.hidden]	boolean	signals the page is being hidden; drains the send queue immediately rather than waiting for the next timer tick

Example

pendo.flushNow()

isSendingEvents() ⇒ Boolean

Returns true if event collection is currently enabled.

Example

pendo.stopSendingEvents()
pendo.isSendingEvents() => false
pendo.startSendingEvents()
