Couchbase Monitoring

Overview

Couchbase Server is an open source, distributed, No SQL document-oriented database. It exposes a fast key-value store with managed cache for sub-millisecond data operations. Couchbase Server is specialized to provide low-latency data management for large-scale interactive web, mobile, and IoT applications.
