Power Control Service (PCS) v1

Scroll down for code samples, example requests and responses. Select a language for code samples from the tabs above or the mobile navigation menu.

The Power Control Service (PCS) performs power-related operations on system components - nodes, blades, and chassis. PCS refers to system components by their xname, or system identifier.

This REST API provides the following functions:

Turn xnames on or off.
Perform hard and soft reset actions.
Set and retrieve power capping parameters and capabilities.
Get node rules which are various parameters relating to power operations.

Resources

/transitions

Power xname on or off.

/power-status

Get power status of xnames.

/power-cap

/power-cap-snapshot

Get and set power capping parameters.

Workflows

Set Power Cap for a list of targets

PATCH /power-cap

Send a JSON payload with a list of targets and power capping parameters to be applied to the targets. This is a non-blocking operation. A task ID is returned, used to query the status of the task and get the requested information.

Get Power Cap status and information for a power cap task

GET /power-cap/{taskID}

Retrieve status of specified power cap PATCH operation and current values.

Get Power Cap parameters and capabilities for a list of targets

POST /power-cap/snapshot

Send a JSON payload with a list of target xnames. This will launch a task and return a snapshot ID which can be queried for status.

Get status and current Power Cap settings from recent power cap snapshot

GET /power-cap/{taskID}

Query the status of a power cap snapshot task. If completed, contains the current power cap values as read from the hardware.

GET /health

Query the health of the service

The health resource returns health information about the PCS service and its dependencies. This actively checks the connection between PCS and the following:

KV store
Distributed locking subsystem
Hardware State Manager
Vault
Task Runner Service status and mode

This is primarily intended as a diagnostic tool to investigate the functioning of the PCS service.
