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 MetricMetric Display NameUnitAggregation 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.
