Raw Blame History

9.3.0

Project

  • Bump up the embedded swctl version in OAP Docker image.

OAP Server

  • Add component ID(133) for impala JDBC Java agent plugin and component ID(134) for impala server.
  • Use prepareStatement in H2SQLExecutor#getByIDs.(No function change).
  • Bump up snakeyaml to 1.32 for fixing CVE.
  • Fix DurationUtils.convertToTimeBucket missed verify date format.
  • Enhance LAL to support converting LogData to DatabaseSlowStatement.
  • [Breaking Change] Change the LAL script format(Add layer property).
  • Adapt ElasticSearch 8.1+, migrate from removed APIs to recommended APIs.
  • Support monitoring MySQL slow SQLs.
  • Support analyzing cache related spans to provide metrics and slow commands for cache services from client side
  • Optimize virtual database, fix dynamic config watcher NPE when default value is null
  • Remove physical index existing check and keep template existing check only to avoid meaningless retry wait in no-init mode.
  • Make sure instance list ordered in TTL processor to avoid TTL timer never runs.
  • Support monitoring PostgreSQL slow SQLs.
  • [Breaking Change] Support sharding MySQL database instances and tables by Shardingsphere-Proxy. SQL-Database requires removing tables log_tag/segment_tag/zipkin_query before OAP starts, if bump up from previous releases.
  • Fix meter functions avgHistogram, avgHistogramPercentile, avgLabeled, sumHistogram having data conflict when downsampling.
  • Do sorting readLabeledMetricsValues result forcedly in case the storage(database) doesn't return data consistent with the parameter list.
  • Fix the wrong watch semantics in Kubernetes watchers, which causes heavy traffic to API server in some Kubernetes clusters, we should use Get State and Start at Most Recent semantic instead of Start at Exact because we don't need the changing history events, see https://kubernetes.io/docs/reference/using-api/api-concepts/#semantics-for-watch.
  • Unify query services and DAOs codes time range condition to Duration.

UI

  • Fix: tab active incorrectly, when click tab space
  • Add impala icon for impala JDBC Java agent plugin.
  • (Webapp)Bump up snakeyaml to 1.31 for fixing CVE-2022-25857
  • [Breaking Change]: migrate from Spring Web to Armeria, now you should use the environment variable name SW_OAP_ADDRESS to change the OAP backend service addresses, like SW_OAP_ADDRESS=localhost:12800,localhost:12801, and use environment variable SW_SERVER_PORT to change the port. Other Spring-related configurations don't take effect anymore.
  • Polish the endpoint list graph.
  • Fix styles for an adaptive height.
  • Fix setting up a new time range after clicking the refresh button.
  • Enhance the process topology graph to support dragging nodes.
  • UI-template: Fix metrics calculation in general-service/mesh-service/faas-function top-list dashboard.
  • Update MySQL dashboard to visualize collected slow SQLs.
