与Couchbase群集的连接状态

Question

How can monitoring status connection to couchbase cluster consisting few servers? In docs to couchbase, class CouchbaseClaster doesn't have methods for checks connection status to cluster. One of the solution it's checks to connection to bucket with CouchbaseManager.hasBucket(), but's think it's bad. Maybe someone faced such a challenge?

PS: I apologize for possible mistakes, becouse I don't speak English well.

Answer 1

I have found it unnecessary to monitor the database connection. I instead add error handling code to recover from such scenarios.

With the Couchbase Java SDK you can encounter a variety of exceptions. Some indicate temporary problems while others are permanent problems. For temporary problems, consider using a retry mechanism . For permanent problems , log the error and trigger a notification through a monitoring application.

The Couchbase Java SDK will also log connectivity issues. It periodically contacts the cluster to keep its Cluster Map up to date with any cluster changes. If it has problems doing that, it will log a message.
