Enhanced Metrics

AppSync supports Enhanced metrics. You can configure them under the appSync.enhancedMetrics attribute.

Quick start

appSync:
  name: my-api
  enhancedMetrics:
    DataSourceLevelMetricsBehavior: 'FULL_REQUEST_DATA_SOURCE_METRICS'
    OperationLevelMetricsConfig: 'ENABLED'
    ResolverLevelMetricsBehavior: 'PER_RESOLVER_METRICS'

Configuration

All three properties are required by AWS. See the official documentation for details.

• DataSourceLevelMetricsBehavior: FULL_REQUEST_DATA_SOURCE_METRICS | PER_DATA_SOURCE_METRICS
• OperationLevelMetricsConfig: ENABLED | DISABLED
• ResolverLevelMetricsBehavior: FULL_REQUEST_RESOLVER_METRICS | PER_RESOLVER_METRICS

Per-resolver metrics

When ResolverLevelMetricsBehavior is PER_RESOLVER_METRICS, AppSync only emits metrics for resolvers whose MetricsConfig is ENABLED. Set this per resolver with metricsConfig:

appSync:
  resolvers:
    Query.user:
      kind: UNIT
      dataSource: my_table
      metricsConfig: 'ENABLED'

metricsConfig defaults to DISABLED and is only emitted into the generated CloudFormation when enhancedMetrics is configured, so existing stacks that don't use enhanced metrics are unaffected. With FULL_REQUEST_RESOLVER_METRICS, metrics are emitted for all resolvers regardless of metricsConfig.
