📝 Walkthrough

Walkthrough

The PR updates KPI metadata and baseline matching, centralizes postprocess output paths, standardizes performance plot ordering and sizing, adds cluster configuration control, and changes KPI analysis invocation result fields.

Changes

KPI pipeline

Layer / File(s) Summary
KPI record and label contract
projects/llm_d/postprocess/llm_d/parsing/kpis.py, projects/caliper/engine/kpi/format.py, projects/caliper/tests/stub_plugin.py, projects/caliper/tests/test_kpi_format.py
KPI records now use catalog metadata. higher_is_better is removed from extracted labels. KPI and test labels are merged during formatting and flattening.
Baseline matching and report structure
projects/caliper/engine/kpi/analyze.py, projects/caliper/tests/test_kpi_analyze.py
Label filtering is centralized. Baseline relevance permits extra baseline labels. Same-version filtering always runs. Reports separate relevant and irrelevant baseline sources.

Postprocess output handling

Layer / File(s) Summary
Output directory API
projects/core/library/postprocess.py, projects/caliper/orchestration/postprocess.py
Postprocess entry points replace visualize_output_dir with output_dir.
Step output routing
projects/caliper/orchestration/postprocess.py
Postprocess steps use self.output_dir for KPI, AI, S3, visualization, analysis, reports, and status-file paths.

Performance plot standardization

Layer / File(s) Summary
Configuration ordering
projects/guidellm/postprocess/guidellm/plotting/performance_analysis.py
Dataframe rows, configuration lists, and legends use custom ordering for heterogeneous and multi-turn configurations.
Standard plot rendering
projects/guidellm/postprocess/guidellm/plotting/performance_analysis.py
Throughput, latency, token-throughput, and TTFT plots use shared dimensions and explicit configuration orders.
Percentile and report sizing
projects/guidellm/postprocess/guidellm/plotting/performance_analysis.py
Percentile plots and generated PNGs use shared dimensions. Embedded report images use a 1700px maximum width.

Analysis invocation results

Layer / File(s) Summary
Invocation result contract
projects/caliper/orchestration/caliper_invocation.py
Successful analysis results use a fixed success status. Failure results use an optional error field and updated fallback text. Debug scripts use a .sh.txt extension.

Configuration controls

Layer / File(s) Summary
Cluster configuration control
projects/core/library/config.py, projects/core/tests/test_library_config.py, projects/llm_d/tests/test_profiles.py
init and reload accept apply_cluster_config. Related tests disable cluster-specific preset application.

Diagnostic updates

Layer / File(s) Summary
Postprocessing diagnostics
projects/llm_d/orchestration/ci.py, projects/llm_d/orchestration/test_phase.py
Postprocessing exceptions are logged with stack traces. MLflow pre-creation failures use error-level logging.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 9f2c2

This change can skip regression comparisons, break the normal post-test workflow, publish stale or mismatched KPI artifacts, and omit reports or failure diagnostics in supported configurations. Because these are concrete correctness and availability risks affecting core processing paths, the PR is not ready to merge until they are fixed or explicitly accepted by the owners.

Keep step-result paths relative to self.output_dir.

This step now writes KPI output under self.output_dir, but _run_artifacts_to_kpis records its output relative to env.ARTIFACT_DIR. If self.output_dir is outside that directory, _make_path_relative_to_base reduces the record to a filename. _run_s3_export_step later prefixes that value with env.ARTIFACT_DIR, so S3 export reads a different path than the KPI step wrote. The same contract affects CSV, AI data, and analysis outputs.

Store paths relative to self.output_dir and resolve them from self.output_dir in _run_s3_export_step, or store absolute paths consistently.

Test Description

This test runs the llm_d project using the xks-smoke-mini preset, narrowing the XKS smoke deployment to a single intelligentrouting-tp1-x1 configuration and executing the short Guidellm benchmark on Qwen/Qwen3-0.6B. It is a minimal XKS/CPT smoke validation focused on basic inference serving, KPI collection, and export rather than full release-scale testing.

Keep S3 export inputs rooted in self.output_dir.

When output_dir is outside env.ARTIFACT_DIR, KPI, CSV, AI-data, and analysis runners still store paths relative to env.ARTIFACT_DIR. _make_path_relative_to_base then reduces external paths to a filename. _run_s3_export_step reconstructs that filename under env.ARTIFACT_DIR, so S3 export can upload a missing or unrelated artifact instead of the artifact in the configured output directory.

Store and resolve these step paths against self.output_dir, or preserve absolute paths that are outside it.
