Kevin Doran updated NIFI-15979:
-------------------------------
Description:
NIFI-14991 wired Process Group
identity into the SLF4J MDC for every component log, but it has no concept of a
`Connector`. As a result:
- Logs from inside a connector-managed flow carry `processGroupId/Name/Path`
but
nothing identifying the owning connector or its NAR bundle. The connector's
own
log lines emit no MDC at all (`ExtensionBuilder.buildConnector` constructs the
`ComponentLog` with the no-arg `StandardLoggingContext`).
- Reporting tasks that walk `EventAccess.getControllerStatus()` never see
connector-managed Process Groups — they have no parent and live in
`ConnectorRepository`, separate from the root group.
- A connector implementation has no way to surface custom logging context
(e.g. source schema, table namespace).
#
##
### What changes
*{*}nifi-api{*}*
- `ConnectorInitializationContext.setLoggingAttributes(Map<String, String>)` —
new `default` method; `AbstractConnector` provides a `protected` helper.
- `ProcessGroupStatus` — new `loggingAttributes` field (`Map.of()` default),
included in `clone()` / `merge()`.
- `EventAccess.getConnectorStatuses()` — new `default` returning empty;
implementations override.
*{*}Framework{*}*
- `StandardConnectorNode` holds a `loggingAttributes` map, implements
`GroupedComponent`, and is initialized with reserved framework keys:
`connectorId`, `connectorName`, `connectorComponent` (FQN, mirroring the
existing processor `component` convention), and
`connectorBundleGroup`/`Artifact`/`Version` from the bundle coordinate.
- Reserved keys cannot be overridden by `setLoggingAttributes`; collisions are
dropped with a single WARN. A second WARN fires when a connector sets more
than ~10 custom keys, to surface cardinality risk.
- `StandardProcessGroup.setLoggingAttributes()` merges the owning connector's
keys and recurses into descendants, so every component inside the managed
flow inherits them without needing to know about Connectors.
- `ExtensionBuilder.buildConnector` (and the ghost path) now constructs
`SimpleProcessLogger` with a `StandardLoggingContext` bound to the
`StandardConnectorNode` via the existing `setComponent` late-bind path.
- `AbstractEventAccess.createProcessGroupStatus` snapshots
`group.getLoggingAttributes()` onto the status DTO.
`AbstractEventAccess.getConnectorStatuses()` walks the Connector registry and
returns one status per managed root.
*{*}Tests + docs{*}*
Unit tests for framework keys, propagation into inner components,
reserved-key filtering, `setName` updates, and the new `EventAccess` methods.
Short `administration-guide.adoc` section listing the new keys alongside the
NIFI-14991 documentation.

### Delivery
Two PRs:
1. `nifi-api`: BW-compatible additions only (default impls / optional DTO
field; no behavior change).
2. `nifi`: Framework wiring + tests + docs.

- A connector implementation has no way to surface custom logging context

### What changes
**nifi-api**
- `ConnectorInitializationContext.setLoggingAttributes(Map<String, String>)` —
new `default` method; `AbstractConnector` provides a `protected` helper.
- `ProcessGroupStatus` — new `loggingAttributes` field (`Map.of()` default),
included in `clone()` / `merge()`.
- `EventAccess.getConnectorStatuses()` — new `default` returning empty;
implementations override.
**Framework**
- `StandardConnectorNode` holds a `loggingAttributes` map, implements
`GroupedComponent`, and is initialized with reserved framework keys:
`connectorId`, `connectorName`, `connectorComponent` (FQN, mirroring the
existing processor `component` convention), and
`connectorBundleGroup`/`Artifact`/`Version` from the bundle coordinate.
- Reserved keys cannot be overridden by `setLoggingAttributes`; collisions are

- `ExtensionBuilder.buildConnector` (and the ghost path) now constructs
`SimpleProcessLogger` with a `StandardLoggingContext` bound to the
`StandardConnectorNode` via the existing `setComponent` late-bind path.
- `AbstractEventAccess.createProcessGroupStatus` snapshots
`group.getLoggingAttributes()` onto the status DTO.
`AbstractEventAccess.getConnectorStatuses()` walks the Connector registry and
returns one status per managed root.
**Tests + docs**
Unit tests for framework keys, propagation into inner components,
reserved-key filtering, `setName` updates, and the new `EventAccess` methods.
Short `administration-guide.adoc` section listing the new keys alongside the
NIFI-14991 documentation.
