Obcerv Platform 2.3.0 Copied
Released: 22 April 2024
New features and enhancements Copied
These are the new features and enhancements of this release:
| Issue key | Release description |
|---|---|
| HP-2102 | The Configuration Service is now run as a standalone workload. |
| HP-2139 | Introduced a new OK signal severity type to distinguish between the absence of signals for an entity or metrics (NONE) and situations where signals are present but indicate a positive state (OK). For Geneos namespaced datapoints lacking a defined signal severity or set to None, the severity defaults to None if the signal context indicates Undefined or Inactive. Otherwise, it defaults to OK. |
| HP-2141 | Made the time window optional for GetLatestMetrics, GetLatestStatusMetrics, and GetLatestMetricsCount. |
| HP-2249 | Metrics returned by the metrics query service’s GetMetrics and GetBulkMetrics endpoints now include a new type field that denotes the metric type. |
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:
|
| 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. |
