Dec 1, 2025December 2025 — yugabyte/yugabyte-db: Delivered three high-impact reliability and diagnostics improvements. (1) Stability fix for tserver_export metrics collection to prevent OOM during support bundle generation. Implemented by batching promdump API requests by node_name and by table-level vs non-table-level metrics; per-metric-per-node collection for table metrics to reduce memory pressure. This reduces OOM risk and speeds up support bundles. (2) Enhanced Support Bundle metadata: include Yugaware version and UUID by querying yugaware_property; adds YugawareMetadata with version and yugaware_uuid for diagnostics. (3) OpenTelemetry log export monitoring: new default-enabled alert template to detect otel log export failures, improving proactive ops visibility. All changes tested via UTs, itests, and manual testing; reviews completed by amalyshev and others; differentials referenced: D48789, D49152, D49173.
