Status API

The Status API is a set of read-only HTTP endpoints for inspecting cluster membership, alarm runtime state, effective configuration / TTL settings, and per-query debug traces. Hosted by the status feature module on the admin-server REST host (default 17128), alongside /ui-management/*, /inspect/*, /dsl-debugging/*, and /runtime/rule/*. One handler — /status/config/ttl — is also bound on the public REST host (default 12800) so ecosystem tools that discover TTL via REST before issuing /graphql can fetch it without being aware of the admin port.

Hosting

status registers all handlers on the admin-server REST host (default port 17128). Both status and admin-server are enabled by default, so the surface is reachable out of the box. The admin port is gateway-protected per the admin-server security notice. To disable status explicitly, unset SW_STATUS:

export SW_STATUS=                       # disable
export SW_STATUS=default                # default (enabled)

Configuration

status:
  selector: ${SW_STATUS:default}
  default:
    keywords4MaskingSecretsOfConfig: ${SW_DEBUGGING_QUERY_KEYWORDS_FOR_MASKING_SECRETS:user,password,token,accessKey,secretKey,authentication}

keywords4MaskingSecretsOfConfig is consumed by /debugging/config/dump to redact configuration values whose key contains any listed substring.

Endpoints

/status/cluster/nodes

Returns the OAP cluster peer list as the cluster module sees it. Useful for confirming that every node has joined and is reporting back.

curl http://oap:17128/status/cluster/nodes

/status/alarm/rules

Lists registered alarm rules.

/status/alarm/{ruleId}

Per-rule runtime status — current window state, last evaluation, the entities the rule has triggered against.

/status/alarm/{ruleId}/{entityName}

Drill-down: status of one specific entity under a given rule.

/status/config/ttl

Returns the effective TTL configuration the OAP loaded at boot. Reachable on both ports:17128 (admin) and :12800 (public) — so ecosystem tools can call it without admin-port knowledge. Every other /status/* handler is admin-only.

/debugging/config/dump

Dumps the effective configuration that was applied at boot. Values whose key contains any substring listed in keywords4MaskingSecretsOfConfig are redacted. Output is YAML-shaped key=value lines.

The Inspect API uses this endpoint as its REST-URL discovery primitive — clients parse the dump for core.restHost / core.restPort (or the sharing-server overrides) once at session start to learn where the public GraphQL / MQE surface lives.

/debugging/query/...

Runs a named query path with debug tracing enabled and returns the captured DAO / storage spans alongside the result. Useful for diagnosing why a query is slow or returning unexpected data.
