Status - 《Open Policy Agent v0.12.2 Documentation》

Status Service API

Status

OPA can periodically report status updates to remote HTTP servers. The updates contain status information for OPA itself as well as the Bundles that have been downloaded and activated.

OPA sends status reports whenever bundles are downloaded and activated. If the bundle download or activation fails for any reason, the status update will include error information describing the failure.

The status updates will include a set of labels that uniquely identify the OPA instance. OPA automatically includes an id value in the label set that provides a globally unique identifier or the running OPA instance and a version value that provides the version of OPA.

See the Configuration Reference for configuration details.

Status Service API

OPA expects the service to expose an API endpoint that will receive status updates.

POST /status[/<partition_name>] HTTP/1.1
Content-Type: application/json

The partition name is an optional path segment that can be used to route status updates to different backends. If the partition name is not configured on the agent, updates will be sent to /status.
