Oct 1, 2025Month: 2025-10 — htcondor/htcondor delivered targeted improvements to monitoring reliability and job-setup observability. A bug fix enhanced CE Dashboard data retrieval by ensuring hostnames include the default domain when querying Ganglia, reducing data errors for osg-htc.org dashboards. A new feature added Pre-Execution Vacate Metrics by introducing ClassAd attributes NumVacatesPreExecution and NumVacatesByReasonPreExecution, with corresponding updates to core logic (qmgmt.cpp) and documentation/version history. These changes bolster data fidelity, dashboard accuracy, and actionable insights for operators and developers.

Aug 1, 2025August 2025 (htcondor/htcondor) focused on improving eviction observability, robustness of hold/vacate decisions, and code quality. Delivered new eviction analytics attributes, refined eviction logic with code+subcode granularity, updated and documented changes, and completed a targeted code-quality improvement to standardize title casing. These changes enhance operational insight, reliability, and maintainability, aligning with HTCONDOR-3204 and HTCONDOR-3251. Key work delivered this month: - Enhanced eviction tracking: added NumVacates and NumVacatesByReason attributes to the job advertisement to record eviction events (e.g., file transfer errors) and to support analysis; documentation added. - Robust hold-vacate logic: refactored the hold-vacate decision path to use granular code+subcode conditions, improving reliability across eviction scenarios. - Documentation: included comprehensive documentation for the new eviction attributes. - Code quality improvement: replaced a custom title-casing routine with a standardized utility to improve consistency and maintainability.
