Amazon CloudWatch is the service that enables the monitoring of key metrics on various AWS services, including EC2, EBS, and VPC, for NC2 cluster deployments.

Amazon CloudWatch:

Amazon CloudWatch provides monitoring for AWS cloud resources and applications. It collects and tracks metrics, collects and monitors log files, and sets alarms.

Specifically, for NC2 deployments, CloudWatch can be used to monitor key metrics such as CPU utilization, disk I/O, network I/O for EC2 instances, EBS volume performance, and VPC network traffic.

Features:

Metrics Monitoring: Collects and visualizes operational data in the form of metrics, including utilization, performance, and health.

Logs Monitoring: Collects log data, monitors it in real-time, and triggers alarms based on predefined thresholds.

Alarms: Notifies when operational performance thresholds are breached.

Integration with NC2:

By setting up CloudWatch, administrators can ensure they have visibility into the performance and health of their Nutanix clusters on AWS, aiding in proactive management and troubleshooting.

AWS Monitoring Best Practices

When deploying a new NC2 cluster, the AWS Directory Service must be able to resolve the addressgateway-external-api.cloud.nutanix.com.

This external API gateway is critical for the NC2 cluster to communicate with Nutanix services for operations such as management, updates, and licensing.

Ensuring that this address can be resolved allows the cluster to interact properly with the Nutanix cloud infrastructure and services.

References:Refer to the Nutanix documentation on network and DNS requirements for NC2 deployments, specifically the addresses that need to be resolvable for proper functionality.

For issues related to cloud hardware support such as EC2 instances, VPC, etc., the public cloud vendor (AWS in this case) should be contacted. AWS provides support and documentation for their infrastructure and services, ensuring that users can get assistance for any hardware or cloud-specific queries.
