Couchbase Monitoring

The script consumes Couchbase metrics via its REST API and command-line tools to digest the health and performance of a cluster on a regular basis. It captures information about each node's health, including its view of the cluster, and stores this data in a Couchbase bucket using N1QL queries. The goal is to provide a simple implementation that can be leveraged by devops teams to diagnose issues in "war room" settings. The script uses Python as a familiar language for generalization and captures specific statistics such as memory utilization and drain queue metrics, which are important for monitoring a Couchbase cluster. The data is stored in a JSON document with a TTL of 30 days, allowing for easy querying and analysis using N1QL queries.
