CloudWatch not displaying all configured metrics

0

Installed Cloudwatch on 6 EC2 instances. Ran through the configuration wizard & selected Advanced for metrics collection. In the dashboard, CPU & network display properly, but not seeing anything for the physical disk metrics. Checked config log & no errors.
Any thoughts of on why disk not reporting but other categories are?

Hi there,

It looks like you have installed CloudWatch Agent on your EC2 instances and configured using configuration wizard. Assuming that CWAgents are started/restarted after the configuration was generated by the Wizard, or used the configuration which the wizard created.

Which dashboard are you referring to? If you are referring to "Monitoring" tab for your EC2 instances specifically the custom metrics collected by the CWAgent will not be shown in that monitoring section.

Based on the configuration of the namespace for the CloudWatch Agent's collected metrics, you should be able to find them under CWAgent (1) namespace(default one) otherwise as per your specification during the configuration wizard. Please follow below steps to find the metrics collected by your CloudWatch Agent:

  • Login to AWS Management Console -> Go to CloudWatch console
  • Go to "All metrics" from the left hand panel under Metrics section
  • On the main section of the page, you should see the namespace CWAgent or the namespace that you have specified if applicable
  • Click on the namespace to see the metrics collected by your CloudWatch Agent.
