Mar 1, 2026Monthly summary for 2026-03 (GoogleCloudPlatform/PerfKitBenchmarker): Implemented Azure provisioning error handling improvements and troubleshooting guidance to better manage capacity constraints during VM provisioning and AKS node pool creation. Classified capacity-related errors as InsufficientCapacityCloudFailure, and added clear error messages plus remediation steps for Azure VM capacity, quotas, and node pool configuration. The work encompassed two commits (a73f173e8eb30e3c0b65b0f04571fa7c42d35c74; 68977afb9006236c47a3339680d168b5e48eb7b1), which respectively mark 'Capacity Restrictions' as InsufficientCapacityCloudFailure and handle AKS node pool creation failures due to capacity issues. Overall impact: more reliable Azure provisioning, faster triage and remediation for capacity issues, and improved guidance for capacity planning, reducing downtime and enabling smoother deployments for customers using Azure resources. Technologies/skills demonstrated: Python-based error handling and classification, robust exception messaging, Azure provider considerations for PerfKitBenchmarker, AKS provisioning workflows, and documentation of troubleshooting guidance.

Nov 1, 2024November 2024: Delivered a key enhancement to PerfKitBenchmarker by integrating Sysbench latency metrics (min, avg, max, 95th percentile) with throughput metrics (TPS/QPS). This enrichment enables direct correlation between latency and throughput, improving interpretation of benchmark results and informing performance tuning. The changes focus on associating latency metrics with qps/tps in the benchmark analytics pipeline, as reflected in the commit that attaches latency data to throughput metrics.
