The cloudwatch-exporter pod is using kube2iam to assume an AWS role with
the "AmazonRDSFullAccess" policy:
iam.amazonaws.com/role: k8s-ns-cloudwatch-exporter-role
config.yml: |-
---
region: us-east-1
delay_seconds: 30
metrics:
- aws_namespace: AWS/RDS
aws_metric_name: CPUUtilization
aws_dimensions: [DBInstanceIdentifier]
aws_statistics: [Average]
When using aws cli with the same role in a k8s pod:
bash-4.2# aws cloudwatch list-metrics --namespace AWS/RDS --metric-name
CPUUtilization --dimensions Name=DBInstanceIdentifier,Value=some-pg
{
"Metrics": [
{
"Namespace": "AWS/RDS",
"MetricName": "CPUUtilization",
"Dimensions": [
{
"Name": "DBInstanceIdentifier",
"Value": "some-pg"
}
]
}
]
}
localhost:9104/metrics only shows:
# HELP cloudwatch_requests_total API requests made to CloudWatch # TYPE
cloudwatch_requests_total counter
cloudwatch_requests_total{action="listMetrics",namespace="AWS/RDS",} 47.0 #

while expecting something like:

What am I missing?
