Obcerv Platform 2.2.0 Copied

Released: 27 March 2024

New features and enhancements Copied

These are the new features and enhancements of this release:

Issue key Release description
HP-1463 Added support for seeding tasks with historic metric data from Timescale.
HP-1896 Added support for seasonal model pipeline and view.
HP-1954 Added DPD task namespace and name to the Signals context map.
HP-1962 Grouping by entity attributes now available in MetricQueryService.
HP-1972 Added GetMetricAggregations in the metric query service that supports Map/Reduce aggregations for metric datapoints.
HP-1976 Added support for histograms in data pipeline aggregation tasks.
HP-2087 Added support for aggregation of numeric attributes.
HP-2164 The YAML in config maps is now readable when viewed through kubectl get -o yaml.
HP-2166 Added support for Map/Reduce semantics in DPD pipeline tasks and view subscriptions.
HP-2197 Added stddev and variance functions to GetMetrics and GetBulkMetrics.
HP-2247 Optimized autovacuum settings for non-hypertables to improve performance, focusing on specific configurations for autovacuum_analyze, autovacuum_vacuum, and fillfactor. Notably, autovacuum_naptime has been reduced to 30 seconds, decreasing dead tuple accumulation and ensuring that tables remain efficient. These adjustments were designed to enhance vacuuming efficiency and table responsiveness.
HP-2248 Added a pre-install validation check to ensure that the last installed version matches the version being installed.
HP-2250 Updated containment rules for the Azure plugin.
HP-2252 Updated containment rules for the GCP plugin.
HP-2259 Updated RocksDB configuration for DownsampledMetrics stream memory usage.
HP-2266 Updated containment rules for the AWS plugin.
HP-2267 Added containment rules for FKM data that originates from Kubenetes and forms FKM data including the new originalSeverity data.
HP-2268 Added containment rules for the MongoDB plugin.
HP-2277 Updated the Kube hierarchy to move a node up.
HP-2282 Added new endpoints in Metric Query Service for getting merged histograms over a time period:
  • GetMergedHistogram: returns a merged histogram of all matching histogram time series.
  • GetMergedHistograms: returns merged histograms per matching entity or group of entities defined by one or more dimensions and/or attributes.
HP-2314 Parameterized durations used in default eviction rules.
HP-2326 Made the sinkd evid cache size configurable and updated the minimum and maximum cache constraints.

Issues fixed Copied

These are the issues we have fixed in this release:

Issue key Release description
HP-1595 The entity stream now enforces a limit (500 by default) to the number of distinct signals that can be attached to a single entity. Once the limit is exceeded, signals continue being processed but the entity’s severity is no longer updated and the entity is marked with an events-partially-applied attribute. The attribute gets cleared and the entity’s severity updates again once the number of open signals for the entity drops back under the clearing limit (300 by default).
HP-2253 Fixed an issue where GetMetricMetadata did not correctly match the none unit.
HP-2260 Fixed an issue causing some signals created in short sequence via the API to be discarded by the entities subsystem, which led to an inconsistency between entity severities and signals timelines.
HP-2264 Upgrade Keycloak to version 23.0.4 to resolve CVE-2023-6134.
HP-2270 The configuration installer now handles conflict with custom entity containment rules during upgrades.
HP-2275 Styles are now correctly loaded on the Keycloak login page.
HP-2276 Metric requests using the Bucket Function Percentile now require the percentile value to be specified within the exclusive range (0,1).
HP-2278 Fixed unit normalization in DPD.
HP-2294 Deployment no longer fails to complete when using downsampledMetricsStream.storeRetention with minimum config.
HP-2310 Fixed an issue where, under certain conditions, some entities would remain active forever, preventing them from being evicted.
HP-2322 Fixed an error that caused a deadlock due to entity updates.
