• Advanced process manager for production Node.js applications. Load balancer, logs facility, startup script, micro service management, at a glance.
  • Call Amazon CloudWatch to retrieve the memory usage metric data that exists for the EC2 instance Assign an IAM role to the EC2 instance with an IAM policy granting access to the desired metric Answer : Install the CloudWatch agent on the EC2 instance to push memory usage to an Amazon CloudWatch custom metric
  • Because the default EC2 metrics are sent from the EC2 server - the host system for the EC2 instances. Memory Usage of any individual EC2 instance is not something that the hypervisor is capable of seeing - by design.
  • Aug 25, 2020 · The CloudWatch service is automatically enabled to collect free metrics for your AWS services and requires no additional configuration for the Splunk Add-on for AWS.
