A cluster is a collection of individual HSMs that AWS CloudHSM keeps in synchronization.
For example, if you can think of a cluster as one logical HSM, when you do a task or operation on one HSM in a cluster, the other HSMs in that cluster are automatically kept up to date.
You can:
- Create a cluster that has from 1 to 28 HSMs. Default limit: 6 HSMs per AWS account per AWS region.
- Place the HSMs in different Availability Zones in an AWS Region.
- Add more HSMs to a cluster for higher performance.
Use the AWS public cloud integration to discover and collect metrics against the AWS service.

Supported metrics
| OpsRamp Metric | AWS Metric | Metric Display Name | Unit | Aggregation Type | Description |
|---|---|---|---|---|---|
| aws_cloudhsm_HsmUnhealthy | HsmUnhealthy | Hsm Unhealthy | None | Average | The HSM instance is not performing properly. AWS CloudHSM automatically replaces unhealthy instances for you. |
| aws_cloudhsm_HsmTemperature | HsmTemperature | Hsm Temperature | None | Average | The junction temperature of the hardware processor. The system shuts down if temperature reaches 110 degrees Centigrade. |
| aws_cloudhsm_HsmKeysSessionOccupied | HsmKeysSessionOccupied | Hsm Keys Session Occupied | None | Average | The number of session keys being used by the HSM instance. |
| aws_cloudhsm_HsmKeysTokenOccupied | HsmKeysTokenOccupied | Hsm Keys Token Occupied | None | Average | The number of token keys being used by the HSM instance and the cluster. |
| aws_cloudhsm_HsmSslCtxsOccupied | HsmSslCtxsOccupied | Hsm Ssl Ctxs Occupied | None | Average | The number of end-to-end encrypted channels currently established for the HSM instance. Up to 2,048 channels are allowed. |
| aws_cloudhsm_HsmSessionCount | HsmSessionCount | Hsm Session Count | None | Average | The number of open connections to the HSM instance. |
| aws_cloudhsm_HsmUsersAvailable | HsmUsersAvailable | Hsm Users Available | None | Average | The number of additional users that can be created. This equals the maximum number of users (listed in HsmUsersMax) minus the users created to date. |
| aws_cloudhsm_HsmUsersMax | HsmUsersMax | Hsm Users Max | None | Average | The maximum number of users that can be created on the HSM instance. |
| aws_cloudhsm_InterfaceEth2OctetsInput | InterfaceEth2OctetsInput | Interface Eth2Octets Input | None | Average | The cumulative sum of incoming traffic to the HSM to date. |
| aws_cloudhsm_InterfaceEth2OctetsOutput | InterfaceEth2OctetsOutput | Interface Eth2Octets Output | None | Average | The cumulative sum of outgoing traffic to the HSM to date. |
| aws_cloudhsm_InterfaceEth2DroppedInput | InterfaceEth2DroppedInput | Interface Eth2Dropped Input | None | Average | Interface Eth2 Packets Input. |
| aws_cloudhsm_InterfaceEth2DroppedOutput | InterfaceEth2DroppedOutput | Interface Eth2Dropped Output | None | Average | Interface Eth2 Packets Output. |
| aws_cloudhsm_InterfaceEth2ErrorsInput | InterfaceEth2ErrorsInput | Interface Eth2Errors Input | None | Average | Interface Eth2 Errors Input. |
| aws_cloudhsm_InterfaceEth2ErrorsOutput | InterfaceEth2ErrorsOutput | Interface Eth2Errors Output | None | Average | Interface Eth2 Errors Input. |
