Cloudwatch dashboard does not show Igraph(PMET) metrics
I am trying to add igraph(PMET) metrics to a CloudWatch Dashboard. With identical metric query parameters, for the same account, same region, I can see the metric in igraph, this means the metrics are being received by igraph. But cloudwatch with the same metric parameters shows empty result. In the same dashboard, I do see PMET metrics in another marketplace.
Igraph metric parameters
Schema Name: Service
DataSet: Test:Prod
Marketplace: aws-cookie-monster-devo.amazon.com
HostGroup: ALL
Host: ALL
ServiceName: CMEventProcessor
MethodName: ALL
Client: ALL
MetricClass: NONE
Instance: NONE
Metric: HM_TLS.HM_CERT.VALIDATION_SUCCESS
CW metric parameters
[ "Service", "HM_TLS.HM_CERT.VALIDATION_SUCCESS", "Client", "ALL", "DataSet", "Test:Prod", "Host", "ALL", "HostGroup", "ALL", "Instance", "NONE", "Marketplace", "aws-cookie-monster-devo.amazon.com", "MethodName", "HM_TLS.VALIDATION", "MetricClass", "NONE", "ServiceName", "CMEventProcessor", { "label": "CMEventProcessor-us-east-1-devo", "accountId": "igraph", "stat": "Sum", "region": "us-east-1" } ],

Hi Waizi,
Let's dive into your issue now.
Clarifying the Issue
The issue you're facing—CloudWatch Dashboard not displaying Igraph(PMET) metrics—might be rooted in permissions, data publishing gaps, or subtle mismatches in your metric query. Even though the metrics are visible elsewhere, CloudWatch requires specific configurations and permissions to display them properly. Let’s break this down step by step, with permissions being the first thing to check.
1. Verify IAM Permissions
CloudWatch requires appropriate IAM permissions to access and display metrics:
- Ensure the IAM role or user querying CloudWatch has these permissions:
cloudwatch:GetMetricDatacloudwatch:ListMetrics
To confirm that CloudWatch has visibility into the metrics, run the following command in the AWS CLI:
aws cloudwatch list-metrics --namespace "Service" --region us-east-1
If the expected metrics do not appear, it’s likely due to permissions or an issue with the namespace.
2. Check Metric Data Consistency
While Igraph confirms metrics are being received, subtle mismatches might prevent CloudWatch from displaying them:
- Double-check the metric parameters (e.g., Service, DataSet, HostGroup, ServiceName) for spelling and casing consistency.
- Confirm you’re querying the correct region (us-east-1 in your case).
3. Verify Namespace and Metric Visibility
CloudWatch relies on a specific namespace for metrics. Ensure that the PMET metrics are being pushed to the expected namespace:
- Namespaces must match exactly what CloudWatch expects. Even small differences, such as extra spaces or casing, can prevent the metric from appearing.
- Use the AWS CLI to confirm that the metric exists under the correct namespace:
aws cloudwatch list-metrics --namespace "Service" --region us-east-1
If the metric doesn’t appear in the output, you may need to verify that the service or third-party source is pushing the metrics correctly to CloudWatch.
4. Metric Publishing Intervals and Gaps
CloudWatch requires metrics to be published at fixed intervals (e.g., 1 minute or 5 minutes):
- Check that PMET metrics are being published consistently. Gaps in publishing (visible in Igraph) may cause CloudWatch to miss them.
5. Cross-Account or Marketplace Issues
If the PMET metrics are visible in another marketplace but not in your CloudWatch Dashboard:
- Confirm permissions and configurations for cross-account metric sharing.
- Verify that the marketplace service (aws-cookie-monster-dev) is correctly pushing metrics to your account.
Summary
From your screenshots and description, the issue likely stems from IAM permissions, inconsistencies in metric publishing, or mismatches in query parameters. Start by ensuring the IAM role or user querying CloudWatch has the right permissions (cloudwatch:GetMetricData and cloudwatch:ListMetrics). Then confirm visibility with the AWS CLI and validate all query configurations.
If the metrics still don’t appear, consider checking for cross-account access issues or marketplace-specific configurations.
Let me know if you’d like further steps or help troubleshooting permissions! 🚀
