## 9.4.0
|
|
|
|
#### Project
|
|
|
|
* Bump up Zipkin and Zipkin lens UI dependency to 2.24.0.
|
|
|
|
#### OAP Server
|
|
|
|
* Add `ServerStatusService` in the core module to provide a new way to expose booting status to other modules.
|
|
* Adds Micrometer as a new component.(ID=141)
|
|
* Refactor session cache in MetricsPersistentWorker.
|
|
* Cache enhancement - don't read new metrics from database in minute dimensionality.
|
|
|
|
```
|
|
// When
|
|
// (1) the time bucket of the server's latest stability status is provided
|
|
// 1.1 the OAP has booted successfully
|
|
// 1.2 the current dimensionality is in minute.
|
|
// (2) the metrics are from the time after the timeOfLatestStabilitySts
|
|
// (3) the metrics don't exist in the cache
|
|
// the kernel should NOT try to load it from the database.
|
|
//
|
|
// Notice, about condition (2),
|
|
// for the specific minute of booted successfully, the metrics are expected to load from database when
|
|
// it doesn't exist in the cache.
|
|
```
|
|
|
|
* Remove the offset of metric session timeout according to worker creation sequence.
|
|
* Correct `MetricsExtension` annotations declarations in manual entities.
|
|
* Support component IDs' priority in process relation metrics.
|
|
* Remove abandon logic in MergableBufferedData, which caused unexpected no-update.
|
|
* Fix miss set `LastUpdateTimestamp` that caused the metrics session to expire.
|
|
* Rename MAL rule `spring-sleuth.yaml` to `spring-micrometer.yaml`.
|
|
* Fix memory leak in Zipkin API.
|
|
* Remove the dependency of `refresh_interval` of ElasticSearch indices from `elasticsearch/flushInterval` config. Now,
|
|
it uses `core/persistentPeriod` + 5s as `refresh_interval` for all indices instead.
|
|
* Change `elasticsearch/flushInterval` to 5s(was 15s).
|
|
* Optimize `flushInterval` of ElasticSearch BulkProcessor to avoid extra periodical flush in the continuous bulk streams.
|
|
* An unexpected dot is added when exp is a pure metric name and expPrefix != null.
|
|
* Support monitoring MariaDB.
|
|
* Remove measure/stream specific interval settings in BanyanDB.
|
|
* Add global-specific settings used to override global configurations (e.g `segmentIntervalDays`, `blockIntervalHours`) in BanyanDB.
|
|
* Use TTL-driven interval settings for the `measure-default` group in BanyanDB.
|
|
* Fix wrong group of non time-relative metadata in BanyanDB.
|
|
* Refactor `StorageData#id` to the new StorageID object from a String type.
|
|
* Support multiple component IDs in the service topology level.
|
|
* Add `ElasticSearch.Keyword` annotation to declare the target field type as `keyword`.
|
|
* [Breaking Change] Column `component_id` of `service_relation_client_side` and `service_relation_server_side` have been replaced by `component_ids`.
|
|
* Support `priority` definition in the `component-libraries.yml`.
|
|
* Enhance service topology query. When there are multiple components detected from the server side,
|
|
the component type of the node would be determined by the priority, which was random in the previous release.
|
|
* Remove `component_id` from `service_instance_relation_client_side` and `service_instance_relation_server_side`.
|
|
* Make the satellite E2E test more stable.
|
|
* Add Istio 1.16 to test matrix.
|
|
* Register ValueColumn as Tag for Record in BanyanDB storage plugin.
|
|
* Bump up Netty to 4.1.86.
|
|
* Remove unnecessary additional columns when storage is in logical sharding mode.
|
|
* Fix ServiceMeshServiceDispatcher overwrite ServiceDispatcher debug file when open SW_OAL_ENGINE_DEBUG.
|
|
|
|
#### UI
|
|
|
|
* Add Zipkin Lens UI to webapp, and proxy it to context path `/zipkin`.
|
|
* Migrate the build tool from vue cli to Vite4.
|
|
* Fix Instance Relation and Endpoint Relation dashboards show up.
|
|
|
|
#### Documentation
|
|
|
|
* Remove Spring Sleuth docs, and add `Spring MicroMeter Observations Analysis` with the latest Java agent side
|
|
enhancement.
|
|
* Update `monitoring MySQL document` to add the `MariaDB` part.
|
|
* Reorganize the protocols docs to a more clear API docs.
