StackExchange.Redis: Get the count of channel subs

Question

is there a way to get the number of channel subscriptions to a specific Redis channel through the StackExchange.Redis library? When interacting with Redis directly, it would work with the PUBSUB NUMSUB command (http://redis.io/commands/pubsub) but I don't see an equivalent call in the C# client library.

Answer 1

This is a server command (as opposed to a database command), so the same guidance applies as for KEYS, SCAN, FLUSHDB, etc. Short version: use GetServer(). Longer version: read the linked article above.

The PUBSUB methods are:

• PUBSUB CHANNELS: server.SubscriptionChannels[Async](...)
• PUBSUB NUMPAT: server.SubscriptionPatternCount[Async](...)
• PUBSUB NUMSUB: server.SubscriptionSubscriberCount[Async](...)
