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 | Metric Display Name | Unit | Aggregation Type |
|---|---|---|---|
| aws_cloudhsm_HsmUnhealthy The HSM instance is not performing properly. AWS CloudHSM automatically replaces unhealthy instances. The cluster size can be proactively expanded to reduce performance impact while the HSM is being replaced. | HSM Unhealthy | None | Sum |
| aws_cloudhsm_HsmTemperature Junction temperature of the hardware processor. The system shuts down if temperature reaches 110 degrees Centigrade. | HSM Temperature | None | Average |
| aws_cloudhsm_HsmKeysSessionOccupied Number of session keys being used by the HSM instance. | HSM Keys Session Occupied | None | Sum |
| aws_cloudhsm_HsmKeysTokenOccupied Number of token keys being used by the HSM instance and the cluster. | HSM Keys Token Occupied | None | Sum |
| aws_cloudhsm_HsmSslCtxsOccupied Number of end-to-end encrypted channels currently established for the HSM instance. | HSM Ssl Ctxs Occupied | None | Average |
| aws_cloudhsm_HsmSessionCount Number of open connections to the HSM instance. | HSM Session Count | None | Sum |
| aws_cloudhsm_HsmUsersAvailable Number of additional users that can be created. | HSM Users Available | None | Sum |
| aws_cloudhsm_HsmUsersMax Maximum number of users that can be created on the HSM instance. | HSM Users Max | None | Maximum |
