    Key Features

    • AWS EC2 Metrics: Monitors metrics for EC2 instances, allowing filtering by tags and configuring batch sizes for parallel data fetching.
    • AWS EBS Metrics: Gathers metrics for EBS volumes, with similar filtering and batching capabilities as EC2.
    • AWS S3 Metrics: Collects metrics for S3 buckets, configurable for batch size.
    • AWS RDS Metrics: Monitors RDS instances, with support for filtering and batch size options.
    • Elastic Load Balancer Metrics: Provides metrics for classic, network, and application ELBs with customizable exclusions and batch sizes.
    • DynamoDB Metrics: Tracks the health of DynamoDB tables, allowing for exclusion of specific tables and batch size configuration.
    • ECS Cluster and Service Metrics: Monitors ECS clusters and services, facilitating filtering and parallel fetching of metrics.

    Key Outcomes

    By utilizing these default checks and policies, ServiceNow customers can effectively monitor their AWS resources, ensuring high availability and performance. The configurable options enable tailored monitoring strategies that can adapt to specific operational needs, enhancing overall IT management efficiency.

    Agent Client Collector provides the following default checks and policies for AWS monitoring.
