Foglight for Amazon Neptune
Graph database monitoring, powered by CloudWatch
Description
Amazon Neptune is a fast, reliable, fully managed graph database service that makes it easy to build and run applications that work with highly connected datasets. It supports the popular property-graph and W3C RDF models, and is engineered for high availability with read replicas, point-in-time recovery, and replication across Availability Zones.
Foglight for Amazon Neptune is an SMA cloud-API cartridge. Instead of connecting to the database with JDBC, its FglAM agent polls Amazon CloudWatch for the AWS/Neptune namespace and queries the Neptune management API (DescribeDBClusters / DescribeDBInstances) using AWS SDK v2.
Business Challenge
Neptune exposes a rich set of CloudWatch metrics, but CloudWatch alone makes it hard to see a cluster as a single living system - to relate instance CPU and memory to query latency, storage growth, and replication lag in one place, with history and alerting tuned to a graph workload.
Foglight for Amazon Neptune assembles those CloudWatch series and management-API facts into a cluster-keyed topology, so the whole environment reads as one health surface rather than a wall of disconnected charts.
Key Features
The cartridge is cluster-keyed: the NeptuneCluster is the top-level topology object, with instances rolling up beneath it. IAM access key, secret, and region are supplied as agent properties, so nothing needs to run inside the AWS account beyond the credentials the agent uses.
Collection uses GetMetricData against the AWS/Neptune namespace for performance and storage telemetry, combined with the management API for cluster and instance inventory. The Foglight Rules Engine then evaluates the results to alert on emerging performance and availability issues.
