AWS Cloudwatch Metric

1. Check Metric Creation Status Metric Creation Confirmation: First, ensure that the metric was actually created successfully. Sometimes, metrics can appear to be created but may not be active or visible immediately due to processing delays or configuration issues.

2. Review Custom Namespace Configuration Namespace Verification: Double-check the custom namespace configuration in CloudWatch. Ensure that the namespace is correctly defined and matches exactly what you're searching for in the ALL METRICS section.

3. Inspect Metric Data Data Availability: Use the AWS CLI or the CloudWatch console to manually query the metric and ensure that it contains data points. This can help determine if the issue is with visibility or with the metric itself.

aws cloudwatch get-metric-statistics --namespace YOUR_NAMESPACE --metric-name YOUR_METRIC_NAME --start-time 2024-08-08T00:00:00 --end-time 2024-08-09T00:00:00 --period 3600 --statistics Average

Replace YOUR_NAMESPACE and YOUR_METRIC_NAME with your actual namespace and metric name.

4. Examine IAM Permissions IAM Role Permissions: Ensure that the IAM role or user you're using to view the metrics has the necessary permissions to access CloudWatch metrics. Lack of permissions can sometimes result in metrics not being displayed.

Hi, metrics are not resources, they are not "created" or "deleted" as typical resources. Metrics are data time series, whose name (namespace, name and dimensions) gets indexed when you ingest data to them. In addition to the explanations given by my colleagues previously, I'll try to add a few more tips and cases you may be interested to check.

If you have tried to ingest data to a metric and the corresponding namespace, name and dimensions do not appear, a possible cause may be that you have ingested data with a wrong timestamp, so the data has been rejected. If the ingestion of data has not succeeded because the data you tried to ingest was either too old or too much forward looking, then the metric name is not indexed. If you have tried to ingest data with a proper timestamp, ensure you are looking for your metric in the corresponding account and region. If you have sent data to a region, the metric will only be indexed in that same region and not appear if you browse the console in another region. Once a metric has been indexed, it stays on the index for up 2 weeks after the last ingestion timestamp. If when you first sent data to that metric you have sent data that is now older than 2 weeks, and you haven't sent anymore data to it, then the metric simply has been taken off the index. You need to publish data at least once every 2 weeks to keep the metric on the index.
