IMPROVED
Traces Migration
- Legacy Traces continuityStrengthened the NG 2.16 to NG 3.2.1 Traces migration workflow so legacy dashboards continue working while APM Smart Frames provide access to latest APM data.
- CPU capability validationAdded x86-64-v3 CPU capability checks to upgrade pre-checks before installation or migration begins.
- Trace resource contextAdded source host IP and application name to OpenTelemetry resource attributes and triggers OmniAgent configuration regeneration when application mappings change.
- OTEL Collector preservationPreserved existing OTEL Collector deployment template configuration during the platform upgrade step and updates it separately through the Traces upgrade activity.
- Compatibility and rollbackAdded NG 2.16 Traces backward compatibility, semantic convention normalization for C++ and NodeJS agents, rollback support, rollback dry runs, and automatic rollback control.
IMPROVED
Minor Enhancements
- Air-gapped local registry supportEnhanced local registry support so Helm charts can be uploaded and managed through a configured local registry without depending on GHCR or external registries.
- OmniAgent performanceDisabled log collection overhead to improve OmniAgent performance.
- Security hardeningAdded server-side validation for event export APIs and hardened RUM Collector and local registry Kubernetes workloads.
- Deployment validationAdded resource limit validation for critical platform services including ClickHouse, Kafka, OTEL Collector, PostgreSQL, Renderer, and Reporter.
- Automated vuKube upgradeAdded vukube-upgrade support to simplify automated Kubernetes cluster upgrades during migration to vuKube.
FIXED
Issues Fixed
- ADI and O11ySource fixesFixed ADI discovery probe handling, Java service fingerprinting, Windows log path validation, GHCR pull secrets, Telegraf scheduling, Tomcat migration values, hidden O11ySource fields, and Cassandra module paths.
- Data model permissionsEnforced object-level data model access and fixed Smart Frame creation for data models with thresholds.
- APM and tracingFixed legacy Trace dashboard status_code values, distributed Trace ID propagation across IBMB, FRM, and CBS, and messaging-system supporting service name resolution.
- Agent reliabilityFixed Windows OmniAgent installation by removing unsupported instrumentation flags and improved AIX vuLogAgent forwarding stability.
- Upgrade and platform jobsFixed Traces Kafka engine table cleanup, O11ySource post-job failures, migration job dependencies, and ClickHouse post-job view creation in 2-shard, 2-replica environments.
