# Monitoring Amazon Neptune resources
<a name="monitoring"></a>

Amazon Neptune supports various methods for monitoring database performance and usage:
+ **Instance status** – Check the health of a Neptune cluster's graph database engine, find out what version of the engine is installed, and obtain other instance-related information using the [instance status API](access-graph-status.md).
+ **Graph summary API** – The [graph summary API](neptune-graph-summary.md) lets you quickly get a high-level understanding of your graph data size and content.
**Note**  
Because the graph summary API relies on [DFE statistics](neptune-dfe-statistics.md), it's only available when statistics are enabled, which is not the case on T3 and T4g instance types.
+ **Amazon CloudWatch** – Neptune automatically sends metrics to CloudWatch and also supports CloudWatch Alarms. For more information, see [Monitoring Neptune Using Amazon CloudWatch](cloudwatch.md).
+ **Audit log files** – View, download, or watch database log files using the Neptune console. For more information, see [Using Audit Logs with Amazon Neptune Clusters](auditing.md).
+ **Publishing logs to Amazon CloudWatch Logs** – You can configure a Neptune DB cluster to publish audit log data to a log group in Amazon CloudWatch Logs. With CloudWatch Logs, you can perform real-time analysis of the log data, use CloudWatch to create alarms and view metrics, and use CloudWatch Logs to store your log records in highly durable storage. See [Neptune CloudWatch Logs](cloudwatch-logs.md).
+ **AWS CloudTrail** – Neptune supports API logging using CloudTrail. For more information, see [Logging Amazon Neptune API Calls with AWS CloudTrail](cloudtrail.md).
+ **Event notification subscriptions** – Subscribe to Neptune events to stay informed about what is happening. For more information, see [Using Neptune Event Notification](events.md).
+ **Tagging** – Use tags to add metadata to your Neptune resources and track usage based on tags. For more information, see [Tagging Amazon Neptune resources](tagging.md).
