# Summary [NIFI-16072](https://issues.apache.org/jira/browse/NIFI-16072) Continues incremental framework adjustments initiated under [NIP-19](https://issues.apache.org/jira/browse/NIP-19) to support recording gauge values. The current set of changes adds a `recordProcessSessionEvent()` method to the `ComponentMetricReporter` interface defined in `nifi-framework-api`. This additional method aligns metrics collection in `ProcessSession` implementations to include Counters, Gauges, and FlowFile handling operations. The majority of the changes relate to renaming and moving the `FlowFileEvent` interface from `nifi-framework-components` to `nifi-framework-api`. The interface name is now `ProcessSessionEvent`, aligning more closely with the scope of behavior tracked. The interface itself is moved to `nifi-framework-api` to align with the location of the `ComponentMetricReporter`. The addition of the `recordProcessSessionEvent()` method includes a default implementation with no operations, making it compatible with existing framework extension classes and also making it optional for framework extensions. The move from `FlowFileEvent` to `ProcessSessionEvent` avoids duplicative object creation, and the new method provides clean decoupling of reporting FlowFile metrics from the volatile or persistent storage of such metrics in the `StatusHistoryRepository`. Minor adjustments to `ProcessSessionEvent` include correcting the method name of `getGarbageCollectionMillis` and removing the `getAverageLineageMillis()` in favor of localized calculation where needed. # Tracking Please complete the following tracking steps prior to pull request creation. ### Issue Tracking - [Apache NiFi Jira](https://issues.apache.org/jira/browse/NIFI) issue created ### Pull Request Tracking - Pull Request title starts with Apache NiFi Jira issue number, such as `NIFI-00000` - Pull Request commit message starts with Apache NiFi Jira issue number, as such `NIFI-00000` - Pull request contains [commits signed](https://docs.github.com/en/authentication/managing-commit-signature-verification/signing-commits) with a registered key indicating `Verified` status ### Pull Request Formatting - Pull Request based on current revision of the `main` branch - Pull Request refers to a feature branch with one commit containing changes # Verification Please indicate the verification steps performed prior to pull request creation. ### Build - [X] Build completed using `./mvnw clean install -P contrib-check` - [X] JDK 21 - [X] JDK 25 ### Licensing - [ ] New dependencies are compatible with the [Apache License 2.0](https://apache.org/licenses/LICENSE-2.0) according to the [License Policy](https://www.apache.org/legal/resolved.html) - [ ] New dependencies are documented in applicable `LICENSE` and `NOTICE` files ### Documentation - [ ] Documentation formatting appears as expected in rendered files -- This is an automated message from the Apache Git Service.
