Idle Resource Detection Features

Cloud Sweeper uses asynchronous scanning and cloud-native metrics to automatically identify and tag idle resources across AWS and Azure. Optimize your cloud spend by targeting unused EC2, VMs, disks, databases, and more.

AWS Supported Resources

• EC2 Instances

  Scans all running EC2 instances. Flags as idle if average CPUUtilization (CloudWatch) over a configurable period is below threshold. Idle instances are tagged and can be deleted.

• EBS Volumes

  Detects unattached EBS volumes older than a set threshold and above minimum size. Idle volumes are tagged and can be deleted.

• S3 Buckets

  Finds empty S3 buckets using BucketSizeBytes metrics. Idle buckets are tagged and can be deleted if empty.

• Elastic IPs (EIP)

  Identifies unassociated Elastic IP addresses. Idle EIPs are tagged and can be released.

• ElastiCache Clusters

  Scans Redis and Memcached clusters. Flags clusters with low CPU, memory, connections, and cache hit rate as idle. Idle clusters are tagged.

• ECS Clusters

  Detects ECS clusters with low CPU utilization or no running services/tasks. Idle clusters are tagged.

• EKS Clusters

  Flags EKS clusters with low node CPU utilization or no node groups. Idle clusters are tagged.

• ECR Repositories

  Identifies ECR repositories with no images or no image pulls in the last period. Idle repositories are tagged.

• RDS Database Instances

  Scans RDS instances for low CPU, connections, and IOPS. Idle databases are tagged.

• SQS Queues

  Detects SQS queues with low message and API activity, empty queues, or old inactive queues. Idle queues are tagged.

Azure Supported Resources

• Virtual Machines (Classic & VMSS)

  Scans all classic VMs and VM Scale Sets. Flags as idle if status is "stopped" or "deallocated", or average CPU usage is below 5%.

• Unattached Disks

  Detects managed disks not attached to any VM. Idle disks are tagged.

• Unassociated Public IPs

  Identifies static public IPs with no associated configuration. Idle IPs are tagged.

• Redis Caches

  Flags Redis caches with ConnectedClients < 1 and alloperationsPerSecond < 1 over 24 hours.

• Container Registries (ACR)

  Detects ACRs with zero pushes and pulls over the lookback window. Idle registries are tagged.

• AKS Clusters

  Flags AKS clusters with node_cpu_usage_percentage < 1% over the lookback window.

• App Service Plans

  Detects plans with no hosted web apps and minimal CPU time and request count.

• Container Apps

  Flags Container Apps with zero active replicas or no CPU/HTTP requests over the lookback window.

• MySQL Flexible Servers

  Detects MySQL servers with cpu_percent < 5% and connections == 0 over the lookback window.

• SQL Databases

  Flags SQL databases with avg_cpu_percent < 3% and connections < 5 over the lookback window.

• PostgreSQL Flexible Servers

  Detects PostgreSQL servers with cpu_percent < 5% and connections == 0 over the lookback window.

• Cosmos DB Accounts

  Flags Cosmos DB accounts with NormalizedRUConsumption < 5 over the lookback window.

• Storage Accounts

  Detects storage accounts with average egress < 500 and transactions < 10 over the lookback window.

• Service Bus Namespaces

  Flags namespaces with zero incoming and outgoing messages over the lookback window.

• Event Hub Namespaces

  Detects namespaces with zero incoming bytes over the lookback window.

• Search Services

  Flags Azure Search services with zero queries per second over the lookback window.
