Neptune metrics

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. Ensure your cloud platform is configured in SolarWinds Observability SaaS to collect this service's data. See Add an AWS cloud account. CloudWatch metrics must also be enabled for this service in the AWS Console for the metric data to be available.

Many of the collected metrics from Neptune entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability SaaS for information about entity types in SolarWinds Observability SaaS.

The following table lists some of the metrics collected for these entities. To see the Neptune metrics in the Metrics Explorer, type AWS.Neptune in the search box.

Metric	Units	Description
sw.metrics.healthscore	Percent (%)	Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction. To view the health score for Neptune entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select awsneptune.
AWS.Neptune.BackupRetentionPeriodStorageUsed	bytes	The total amount of backup storage used to support from the Neptune DB cluster's backup retention window
AWS.Neptune.BufferCacheHitRatio	Percent (%)	The percentage of requests that are served by the buffer cache.
AWS.Neptune.ClusterReplicaLag	milliseconds (ms)	For a read replica, the amount of lag when replicating updates from the primary instance.
AWS.Neptune.ClusterReplicaLagMaximum	milliseconds (ms)	The maximum amount of lag between the primary instance and each Neptune DB instance in the DB cluster.
AWS.Neptune.ClusterReplicaLagMinimum	milliseconds (ms)	The minimum amount of lag between the primary instance and each Neptune DB instance in the DB cluster.
AWS.Neptune.ClusterReplicaLagMinimum	milliseconds (ms)	The minimum amount of lag between the primary instance and each Neptune DB instance in the DB cluster.
AWS.Neptune.CPUUtilization	Percent (%)	The percentage of CPU utilization.
AWS.Neptune.EngineUptime	seconds	The amount of time that the instance has been running.
AWS.Neptune.FreeableMemory	bytes	The amount of available random access memory.
AWS.Neptune.GlobalDbDataTransferBytes	bytes	The number of bytes of redo log data transferred from the primary AWS Region to a secondary AWS Region in a Neptune global database.
AWS.Neptune.GlobalDbProgressLag	milliseconds (ms)	The number of milliseconds that a secondary cluster is behind the primary cluster for both user transactions and system transactions.
AWS.Neptune.GlobalDbReplicatedWriteIO	Count	The number of write I/O operations replicated from the primary AWS Region in the global database to the cluster volume in a secondary AWS Region.
AWS.Neptune.GremlinRequestsPerSec	Count per second	Number of requests per second to the Gremlin engine.
AWS.Neptune.GremlinWebSocketOpenConnections	Count	The number of open WebSocket connections to Neptune.
AWS.Neptune.LoaderRequestsPerSec	Count per second	Number of loader requests per second.
AWS.Neptune.MainRequestQueuePendingRequests	Count	The number of requests waiting in the input queue pending execution. Neptune starts throttling requests when they exceed the maximum queue capacity.
AWS.Neptune.NCUUtilization	Percent (%)	At a cluster level, NCUUtilization reports the percentage of maximum capacity being used by the cluster as a whole.
AWS.Neptune.NetworkThroughput	bps	The amount of network throughput both received from and transmitted to clients by each instance in the Neptune DB cluster, in bytes per second. This throughput does not include network traffic between instances in the DB cluster and the cluster volume.
AWS.Neptune.NetworkTransmitThroughput	bps	The amount of outgoing network throughput transmitted to clients by each instance in the Neptune DB cluster, in bytes per second. This throughput does not include network traffic between instances in the DB cluster and the cluster volume.
AWS.Neptune.NumTxCommitted	Count per second	The number of transactions successfully committed per second.
AWS.Neptune.NumTxOpened	Count per second	The number of transactions opened on the server per second.
AWS.Neptune.NumTxRolledBack	Count per second	For write queries, the number of transactions per second rolled back on the server because of errors. For read-only queries, this metric is equal to the number of completed read-only transactions per second.
AWS.Neptune.OpenCypherBoltOpenConnections	Count	The number of open Bolt connections to Neptune.
AWS.Neptune.OpenCypherRequestsPerSec	Count per second	Number of requests per second (both HTTPS and Bolt) to the openCypher engine.
AWS.Neptune.ServerlessDatabaseCapacity	Count	As an instance-level metric, ServerlessDatabaseCapacity reports the current instance capacity of a given Neptune serverless instance, in NCUs. At a cluster-level, ServerlessDatabaseCapacity reports the average of all the ServerlessDatabaseCapacity values of the DB instances in the cluster.
AWS.Neptune.SnapshotStorageUsed	bytes	The total amount of backup storage consumed by all snapshots for a Neptune DB cluster outside its backup retention window, in bytes. Included in the total reported by the TotalBackupStorageBilled metric.
AWS.Neptune.SparqlRequestsPerSec	Count per second	The number of requests per second to the SPARQL engine.
AWS.Neptune.StatsNumStatementsScanned	Count	The total number of statements scanned for DFE statistics since the server started.
AWS.Neptune.TotalBackupStorageBilled	bytes	The total amount of backup storage for which you are billed for a given Neptune DB cluster, in bytes. Includes the backup storage measured by the BackupRetentionPeriodStorageUsed and SnapshotStorageUsed metrics.
AWS.Neptune.TotalClientErrorsPerSec	Count per second	The total number per second of requests that errored out because of client-side issues.
AWS.Neptune.TotalRequestsPerSec	Count per second	The total number of requests per second to the server from all sources.
AWS.Neptune.TotalServerErrorsPerSec	Count per second	The total number per second of requests that errored out on the server because of internal failures.
AWS.Neptune.UndoLogListSize	Count	The count of undo logs in the undo log list.
AWS.Neptune.VolumeBytesUsed	bytes	The total amount of storage allocated to your Neptune DB cluster.
AWS.Neptune.VolumeReadIOPs	Count	The average number of billed read I/O operations from a cluster volume, reported at 5-minute intervals. Billed read operations are calculated at the cluster volume level, aggregated from all instances in the Neptune DB cluster, and then reported at 5-minute intervals.
AWS.Neptune.VolumeWriteIOPs	Count	The average number of write disk I/O operations to the cluster volume, reported at 5-minute intervals.
