Couchbase databases, while initially configured correctly, often require health checks over time due to changes in workload and dataset growth, which can lead to issues such as high resource utilization, slow response times, and poor user experiences. To address these challenges, Couchbase offers health check services through its CoE (Center of Excellence) Professional Services, providing both basic and comprehensive reports that assess cluster health and offer recommendations for improvement. Conducting regular health checks enables better performance tuning, capacity planning, and reduction in total cost of ownership (TCO), as well as ensuring compliance with security policies. The health check process involves analyzing a mix of operational data, server logs, and configurations to identify and rectify underlying issues, with best practices such as ensuring complete data collection and reviewing historical growth patterns to enhance effectiveness. Following up on recommendations and scheduling subsequent checks are also advised to monitor improvements and maintain optimal cluster health.
