How to find number of connection to cluster?

Couchbase Server
1

Is there any way we can find the number of connections to SDK ?
From the official document i can see " Currently there is a hard limit of 10,000 concurrent key-value connections to any cluster node. This effectively means a limit of 10,000 SDK “Bucket” objects."

The Admin UI will show the number of connections to a bucket (note that’s actually a global count connection to all buckets).

How to get number of connections on sync gateway ?

As an aside, the limit was increased to 30,000 in the 4.x time-frame (I forget the exact person off the top of my head).

See the Rest API documentation: Couchbase Server | Couchbase Docs

You’ll want to look at the curr_connections stat.

This curr_connections is per bucket stat ? this increased limit of 30k is for cluster or bucket ?

It’s per node, it’s just shown under bucket as most stats are per-bucket.
