Hello,

I understand that you are trying to capture power-consumption related metrics through collectl tool on a1.metal instance which gave you error "can not find ipmi tool".

I apologize for the inconvenience caused, I would request you to understand below details:

  1. AWS does not expose direct power consumption metrics for individual EC2 instances, including a1.metal instances. None of our instances support IPMI nor any standard BMC type of interface.

  2. The error "can not find ipmi tool" suggests that the collectl tool is trying to use IPMI (Intelligent Platform Management Interface) to gather power-related data. IPMI is generally used for physical hardware management and is not supported for virtualized cloud environments like AWS EC2.

  3. For monitoring and collecting metrics on AWS, it's recommended to use AWS-native tools and services, such as Amazon CloudWatch. CloudWatch provides a wide range of performance-related metrics for EC2 instances, including CPU utilization, network I/O, and disk I/O.

  4. If you need to collect custom metrics or more detailed resource utilization data, you might consider using the CloudWatch agent. This agent can be installed on your EC2 instances to collect additional system-level metrics.

Therefore, you might want to focus on collecting compute-related metrics that can indirectly indicate resource efficiency and utilization. These metrics can help you optimize your workload's performance and potentially reduce energy consumption as a result.

Additionally, you may work with your account management team who can help you get in touch with Sustainability Expert, who can guide you through the tools and frameworks to have a sustainability conversation related to power consumption.

The error "can not find ipmi tool" occurs because the IPMI (Intelligent Platform Management Interface) tools are not installed by default on the instance, and A1 instances, which use AWS Graviton processors (ARM-based), may not support IPMI functionality in the same way as x86-based instances.

Here's why this happens:

  1. Collectl uses IPMI tools to gather power consumption metrics
  2. A1 instances use ARM-based AWS Graviton processors
  3. IPMI support may be limited or unavailable on ARM-based systems

Alternative approaches to monitor power consumption on A1 instances:

  1. Use AWS CloudWatch metrics for instance monitoring
  2. Check CPU utilization as an indirect indicator
  3. Use AWS Cost Explorer for cost-related insights
  4. Consider using monitoring tools specifically designed for ARM-based systems

If you specifically need power consumption metrics, you might want to:

  • Use x86-based instance types that better support IPMI functionality
  • Explore alternative monitoring tools compatible with ARM architecture
  • Use AWS's native monitoring solutions

For A1 instances, it's recommended to rely on CloudWatch metrics for performance monitoring rather than IPMI-based tools.
