AWS monitoring through Instana involves integration with the CloudWatch API to retrieve platform and service metrics. The official IBM Instana Observability documentation affirms that polling intervals for CloudWatch can be set at the Region level. This means an administrator configures how frequently Instana's agent queries CloudWatch within each specified region independently. This level of granularity provides flexibility: for example, mission-critical regions may be monitored more frequently, while others are polled less often to reduce API costs or remain within AWS rate limits. The documentation specifies: "Instana Agents for AWS can be configured with a polling interval for CloudWatch that is set per Region to customize granularity and resource consumption." Polling cannot be set at the account, resource group, or individual service level in default configuration. Instana’s region-based polling helps balance data accuracy and overhead,especially in global or multi-region deployments. If needed, changes are applied through YAML configuration or UI during AWS agent integration setup.
