Cluster OpenBucket Timeout

We’re adding a Couchbase health check to our application that attempts to connect to Couchbase and retrieve a document by key.

I’m testing some failure scenarios. One of these is to change my cluster pool URLs to invalid URLs and then running the healthcheck. Despite changing various timeout settings, the call to OpenBucket is taking over 90 seconds to run. Ideally I want this to timeout within a few seconds so that we can be alerted to the health of the application asap.

What is the correct setting to use to reduce the OpenBucket timeout?
