v1/events.proto#

Messages#

DPSEvent contains the event payload.

Subscribes to one or more events. The subscriber id identifies the receiver, and must be unique among subscribers.

Field	Type	Description
event_names	repeated `string`	Names of the events to subscribe. If multiple, the returned stream will have all these subscribed events. Each event name must not be empty.
subscriber_id	`string`	The unique id of the subscriber. Messages will be queued by subscriber. Must not be empty.
persistent	`bool`	If persistent, the subscription is a persistent subscription. An event queue will be kept for the subscriber and events will be queued when the subscriber is not actively connected. If a subscriber is not persistent, events will be delivered only when the subscriber is connected. Undelivered events will not be queued.

PowerStateEvent is used by nvgrid APIs to notify power state changes

Field	Type	Description
feeds	map `PowerStateEvent.FeedsEntry`	none

Field	Type	Description
metadata	`FeedMetadata.Entry`	Feed limits and constraints
targets	repeated `PowerStateEvent.LoadTarget`	Load targets currently active and future targets
calculated_load	`LoadValue`	Calculated current load
in_flight	`bool`	Is this load target in flight?
power_event_start_time	`google.protobuf.Timestamp`	Event start time
compliant	`bool`	Is the data center compliant?
power_event	`PowerStateEvent.EventType`	none

Field	Type	Description
key	`string`	none
value	`PowerStateEvent.FeedState`	none

LoadTarget is a copy of the nvgrid load target message, with the added ‘active’ field

Field	Type	Description
interval	`Interval`	The start_time is the the time in the future when the constraint should be activated. If omitted, the current local time is assumed. The end_time is the end time for this load target. If there are no overlapping load targets and if the end time is specified, the power will revert back to the default level at this time. If there is an overlapping target, the most recent overlapping target is used. If omitted, there is no end time.
load_constraint	`LoadValue`	The load constraint. If nil, it removes any constraints at the given time, which results in the system falling back to its default constraint.
load_target_strategy	`LoadTargetStrategy`	The strategy specifies what strategy will be used to achieve the desired load_constraint.
active	`bool`	Whether this load target is active
correlation_id	`string`	Optional string that can be used by the caller to identify load targets. The correlation id can be at most 36 bytes, and can contain ascii letters/digits and “-”. It must be a unique id. If not provided, a UUID will be generated.

.proto Type	Notes	C++ Type	Java Type	Python Type
double		double	double	float
float		float	float	float
int32	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead.	int32	int	int
int64	Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead.	int64	long	int/long
uint32	Uses variable-length encoding.	uint32	int	int/long
uint64	Uses variable-length encoding.	uint64	long	int/long
sint32	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int32s.	int32	int	int
sint64	Uses variable-length encoding. Signed int value. These more efficiently encode negative numbers than regular int64s.	int64	long	int/long
fixed32	Always four bytes. More efficient than uint32 if values are often greater than 2^28.	uint32	int	int
fixed64	Always eight bytes. More efficient than uint64 if values are often greater than 2^56.	uint64	long	int/long
sfixed32	Always four bytes.	int32	int	int
sfixed64	Always eight bytes.	int64	long	int/long
bool		bool	boolean	boolean
string	A string must always contain UTF-8 encoded or 7-bit ASCII text.	string	String	str/unicode
bytes	May contain any arbitrary sequence of bytes.	string	ByteString	str
