View resource discovery details

This section describes how to view the details for a resource discovery. These include the resource CIDRs and discovery statuses of accounts monitored under your resource discovery.

Amazon Management Console
To view resource discovery details
  1. Open the IPAM console at

  2. In the navigation pane, choose Resource discoveries.

  3. Choose a resource discovery.

  4. Under Resource discovery details, view details related to the resource discovery, such as Default, which indicates whether the resource discovery is the default. The default resource discovery is the resource discovery automatically created when you create an IPAM.

  5. In the tabs, view the details of a resource discovery:

    • Discovered resources - Resources monitored under a resource discovery. IPAM monitors CIDRs from the following resource types VPCs, Public IPv4 pools, VPC subnets, and Elastic IP addresses.

      • Name (Resource ID) – Resource discovery ID.

      • IP usage – The percentage of IP address space in use. To convert the decimal to a percentage, multiply the decimal by 100. Note the following –

        • For resources that are VPCs, this is the percentage of IP address space in the VPC that's taken up by subnet CIDRs.

        • For resources that are subnets, if the subnet has an IPv4 CIDR provisioned to it, this is the percentage of IPv4 address space in the subnet that's in use. If the subnet has an IPv6 CIDR provisioned to it, the percentage of IPv6 address space in use is not represented. The percentage of IPv6 address space in use cannot currently be calculated.

        • For resources that are public IPv4 pools, this is the percentage of IP address space in the pool that's been allocated to Elastic IP addresses (EIPs).

      • CIDR – Resource CIDR.

      • Region – Resource Region.

      • Owner ID – Resource owner ID.

      • Sample time – The last successful resource discovery time.

    • Discovered accounts: Amazon accounts being monitored under a resource discovery. If you have integrated IPAM with Amazon Organizations, all accounts in the organization are discovered accounts.

      • Account ID – The account ID.

      • Region – The Amazon Region that the account information is returned from.

      • Last attempted discovery time – The last attempted resource discovery time.

      • Last successful discovery time – The last successful resource discovery time.

      • Status – Resource discovery failure reason.

    • Operating regions – The operating Regions for the resource discovery.

    • Resource sharing – If the resource discovery has been shared, the resource share ARN is listed.

      • Resource share ARN – Resource share ARN.

      • Status – The current status of the resource share. Possible values are:

        • Active – Resource share is active and available for use.

        • Deleted – Resource share is deleted and is no longer available for use.

        • Pending – An invitation to accept the resource share is waiting for a response.

      • Created at – When the resource share was created.

    • Tags – A tag is a label that you assign to an Amazon resource. Each tag consists of a key and an optional value. You can use tags to search and filter your resources or track your Amazon costs.
