Method: Mongo::Monitoring::Subscribable#unsubscribe

Defined in:

lib/mongo/monitoring.rb

#unsubscribe(topic, subscriber) ⇒ Object

Note:

Global subscriber registry is separate from per-client subscriber registry. The same subscriber can be subscribed to events from a particular client as well as globally; unsubscribing globally will not unsubscribe that subscriber from the client it was explicitly subscribed to.

Note:

Currently the list of global subscribers is copied into a client whenever the client is created. Thus unsubscribing a subscriber globally has no effect for existing clients - they will continue sending events to the unsubscribed subscriber.

Unsubscribe a listener from an event topic.

If the listener was subscribed to the event topic multiple times, this call removes a single subscription.

If the listener was not subscribed to the topic, this operation is a no-op and no exceptions are raised.

Examples:

Unsubscribe from the topic.

monitoring.unsubscribe(QUERY, subscriber)

Unsubscribe from the topic globally.

Mongo::Monitoring::Global.unsubscribe(QUERY, subscriber)

Parameters:

• The event topic.

• The subscriber to be unsubscribed.

Since:

• 2.6.0
