Introduction
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.
Note
Use the OpsRamp AWS public cloud integration to discover and collect metrics against the AWS service.Setup
To set up the OpsRamp AWS integration and discover the AWS service,
go to AWS Integration Discovery Profile and select Cloud HSM Cluster.
Metrics
| OpsRamp Metric | Metric Display Name | Unit | Aggregation Type | Description |
|---|---|---|---|---|
| aws_cloudhsm_HsmUnhealthy | HSM Unhealthy | None | Average | 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. |
| aws_cloudhsm_HsmTemperature | HSM Temperature | None | Average | Junction temperature of the hardware processor. The system shuts down if temperature reaches 110 degrees Centigrade. |
| aws_cloudhsm_HsmKeysSessionOccupied | HSM Keys Session Occupied | None | Average | Number of session keys being used by the HSM instance. |
| aws_cloudhsm_HsmKeysTokenOccupied | HSM Keys Token Occupied | None | Average | Number of token keys being used by the HSM instance and the cluster. |
| aws_cloudhsm_HsmSslCtxsOccupied | HSM Ssl Ctxs Occupied | None | Average | Number of end-to-end encrypted channels currently established for the HSM instance. |
| aws_cloudhsm_HsmSessionCount | HSM Session Count | None | Average | Number of open connections to the HSM instance. |
| aws_cloudhsm_HsmUsersAvailable | HSM Users Available | None | Average | Number of additional users that can be created. |
| aws_cloudhsm_HsmUsersMax | HSM Users Max | None | Average | Maximum number of users that can be created on the HSM instance. |
| aws_cloudhsm_InterfaceEth2ErrorsInput | Interface Eth2 Errors Input | None | Average | Interface Eth2 Errors Input. |
| aws_cloudhsm_InterfaceEth2ErrorsOutput | Interface Eth2 Errors Output | None | Average | Interface Eth2 Errors Input. |
| aws_cloudhsm_InterfaceEth2PacketsInput | Interface Eth2 Packets Input | None | Average | Interface Eth2 Packets Input. |
| aws_cloudhsm_InterfaceEth2PacketsOutput | Interface Eth2 Packets Output | None | Average | Interface Eth2 Packets Output. |
| aws_cloudhsm_InterfaceEth2DroppedInput | Interface Eth2 Packets Input | None | Average | Interface Eth2 Packets Input. |
| aws_cloudhsm_InterfaceEth2DroppedOutput | Interface Eth2 Packets Output | None | Average | Interface Eth2 Packets Output. |
| aws_cloudhsm_InterfaceEth2OctetsInput | Interface Eth2 Octets Input | None | Average | Interface Eth2 Octets Input. |
| aws_cloudhsm_InterfaceEth2OctetsOutput | Interface Eth2 Octets Output | None | Average | Interface Eth2 Octets Output. |
