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 one of the following happens:
- 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. This includes Discovery bundles.
- A plugin state has changed – All plugin status is reported, and an update to any plugin will trigger a Status API report which contains the latest state.
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.

Status updates contain the following fields:
| Field | Type | Description |
|---|---|---|

bundles | object | Set of objects describing the status for each bundle configured with OPA. |
bundles[_].name | string | Name of bundle that the OPA instance is configured to download. |
bundles[_].active_revision | string | Opaque revision identifier of the last successful activation. |
bundles[_].last_request | string | RFC3339 timestamp of last bundle request. This timestamp should be >= to the successful request timestamp in normal operation. |
bundles[_].last_successful_request | string | RFC3339 timestamp of last successful bundle request. This timestamp should be >= to the successful download timestamp in normal operation. |
bundles[_].last_successful_download | string | RFC3339 timestamp of last successful bundle download. |

processed successfully.
Local Status Logs
Local console logging of status updates can be enabled via the console config option.
This does not require any remote server. Example of minimal config to enable:
status:
console: true
This will dump all status updates to the console. See Configuration Reference for more details.
Warning: Status update messages are somewhat infrequent but can be very verbose! The
metrics.prometheusportion of the status update in particular can create a considerable amount of log text at info level.
Prometheus Status Metrics
Prometheus status metrics can be enabled via the prometheus config option. (see the configuration documentation)
Example of minimal config to enable:
status:
prometheus: true
When enabled the OPA instance’s Prometheus endpoint exposes the metrics described on the monitoring documentation.
