…metrics PR 1 of 3 — Metrics & Observability. New metrics: - per_pod_ready_time: one Sample per pod (pod_name in metadata) so callers can compute p50/p90 across replicas. Uses existing kubernetes_conditions.GetStatusConditionsForResourceType() data. - cpu_utilization_peak_millicores / cpu_utilization_mean_millicores / cpu_utilization_reading_count: CPU polled in a background thread via _CpuUtilizationCollector._Observe() following the same pattern as kubernetes_hpa_benchmark.KubernetesMetricsCollector. Existing max_pod_ready_time metric is preserved unchanged. Adds scenario/workload/cloud metadata to all samples for cross-config comparison (PR 3 will set scenario=optimized for GKE CPU Startup Boost). Flag stubs for --kubernetes_deployment_startup_workload and --kubernetes_deployment_startup_scenario registered now so PR 2 and PR 3 do not need flag renames. PR 2 adds vLLM workload support. PR 3 adds VPA CPU Startup Boost scenario (GKE only).
PR 3 of 3 — Baseline/Optimized Scenario + CPU Startup Boost via VPA. Completes the 4-configuration benchmark matrix: Config 1: GKE w/o cpuboost (scenario=baseline, cloud=GCP) Config 2: AWS w/o cpuboost (scenario=baseline, cloud=AWS) Config 3: AKS w/o cpuboost (scenario=baseline, cloud=Azure) Config 4: GKE w/ cpuboost (scenario=optimized, cloud=GCP) Changes: - kubernetes_deployment_startup_boost_factor flag (default 2). - kubernetes_deployment_startup_vpa_yaml flag (slowjvmstartup_vpa.yaml.j2). - CheckPrerequisites(): raises if scenario=optimized on non-GCP or vLLM. - GetConfig(): sets enable_vpa=True for scenario=optimized. - Prepare(): applies VPA manifest with cpuBoostFactor for optimized. - Run(): adds boost_factor to all sample metadata. - slowjvmstartup_vpa.yaml.j2: VPA with startup boost policy. Stacked on PR GoogleCloudPlatform#6865 (metrics) and PR GoogleCloudPlatform#6867 (vLLM workload).
