  • Upgrade nacos libs caused by CVE-2021-29441 and CVE-2021-29442.
  • Upgrade netty caused by CVE-2019-20444, CVE-2019-20445, CVE-2019-16869, CVE-2020-11612, CVE-2021-21290, CVE-2021-21295 and CVE-2021-21409.
  • Upgrade consul client caused by CVE-2018-1000844, CVE-2018-1000850.
  • Upgrade zookeeper caused by CVE-2019-0201, zookeeper cluster coordinator plugin now requires zookeeper server 3.5+.
  • Upgrade snake yaml caused by CVE-2017-18640.
  • Upgrade embed tomcat caused by CVE-2020-13935.
  • Upgrade commons-lang3 to avoid potential NPE in some JDK versions.
  • OAL supports generating metrics from events.
  • Support endpoint name grouping by OpenAPI definitions.
  • Concurrent create PrepareRequest when persist Metrics
  • Fix CounterWindow increase computing issue.
  • Performance: optimize Envoy ALS analyzer performance in high traffic load scenario (reduce ~1cpu in ~10k RPS).
  • Performance: trim useless metadata fields in Envoy ALS metadata to improve performance.
  • Fix: slowDBAccessThreshold dynamic config error when not configured.
  • Performance: cache regex pattern and result, optimize string concatenation in Envy ALS analyzer.
  • Performance: cache metrics id and entity id in Metrics and ISource.
  • Performance: enhance persistent session mechanism, about differentiating cache timeout for different dimensionality metrics. The timeout of the cache for minute and hour level metrics has been prolonged to ~5 min.
  • Performance: Add L1 aggregation flush period, which reduce the CPU load and help young GC.
  • Support connectTimeout and socketTimeout settings for ElasticSearch6 and ElasticSearch7 storages.
  • Re-implement storage session mechanism, cached metrics are removed only according to their last access timestamp, rather than first time. This makes sure hot data never gets removed unexpectedly.
  • Support session expired threshold configurable.
  • Fix InfluxDB storage-plugin Metrics#multiGet issue.
  • Replace zuul proxy with spring cloud gateway 2.x. in webapp module.
  • Upgrade etcd cluster coordinator and dynamic configuration to v3.x.
  • Configuration: Allow configuring server maximum request header size and ES index template order.
  • Add thread state metric and class loaded info metric to JVMMetric.
  • Performance: compile LAL DSL statically and run with type checked.
  • Add pagination to event query protocol.
  • Performance: optimize Envoy error logs persistence performance.
  • Support envoy cluster manager metrics.
  • Performance: remove the synchronous persistence mechanism from batch ElasticSearch DAO. Because the current enhanced persistent session mechanism, don't require the data queryable immediately after the insert and update anymore.
  • Performance: share flushInterval setting for both metrics and record data, due to synchronous persistence mechanism removed. Record flush interval used to be hardcoded as 10s.
  • Remove syncBulkActions in ElasticSearch storage option.
  • Increase the default bulkActions(env, SW_STORAGE_ES_BULK_ACTIONS) to 5000(from 1000).
  • Increase the flush interval of ElasticSearch indices to 15s(from 10s)
  • Provide distinct for elements of metadata lists. Due to the more aggressive asynchronous flush, metadata lists have more chances including duplicate elements. Don't need this as indicate anymore.
  • Reduce the flush period of hour and day level metrics, only run in 4 times of regular persistent period. This means default flush period of hour and day level metrics are 25s * 4.
  • Performance: optimize IDs read of ElasticSearch storage options(6 and 7). Use the physical index rather than template alias name.
  • Adjust index refresh period as INT(flushInterval * 2/3), it used to be as same as bulk flush period. At the edge case, in low traffic(traffic < bulkActions in the whole period), there is a possible case, 2 period bulks are included in one index refresh rebuild operation, which could cause version conflicts. And this case can't be fixed through core/persistentPeriod as the bulk fresh is not controlled by the persistent timer anymore.
  • The core/maxSyncOperationNum setting(added in 8.5.0) is removed due to metrics persistence is fully asynchronous.
  • The core/syncThreads setting(added in 8.5.0) is removed due to metrics persistence is fully asynchronous.
  • Optimization: Concurrency mode of execution stage for metrics is removed(added in 8.5.0). Only concurrency of prepare stage is meaningful and kept.
  • Fix -meters metrics topic isn't created with namespace issue
  • Enhance persistent session timeout mechanism. Because the enhanced session could cache the metadata metrics forever, new timeout mechanism is designed for avoiding this specific case.
  • Fix Kafka transport topics are created duplicated with and without namespace issue
  • Fix the persistent session timeout mechanism bug.
  • Fix possible version_conflict_engine_exception in bulk execution.
  • Fix PrometheusMetricConverter may throw an IllegalArgumentException when convert metrics to SampleFamily
  • Filtering NaN value samples when build SampleFamily
  • Add Thread and ClassLoader Metrics for the self-observability and otel-oc-rules
  • Simple optimization of trace sql query statement. Avoid "select *" query method
  • Introduce dynamical logging to update log configuration at runtime
  • Fix Kubernetes ConfigMap configuration center doesn't send delete event
  • Breaking Change: emove qps and add rpm in LAL

UI

  • Fix the date component for log conditions.
  • Fix selector keys for duplicate options.
  • Add Python celery plugin.
  • Fix default config for metrics.
  • Fix trace table for profile ui.
  • Fix the error of server response time in the topology.
  • Fix chart types for setting metrics configure.
  • Fix logs pages number.
  • Implement a timeline for Events in a new page.
  • Fix style for event details.

Documentation

  • Add FAQ about Elasticsearch exception type=version_conflict_engine_exception since 8.7.0
  • Add Self Observability service discovery (k8s).
  • Add sending Envoy Metrics to OAP in envoy 1.19 example and bump up to Envoy V3 api.
