Description

- New cloud_governance/policy/common_policies/orion_cost_metrics_rollup.py (cloud-agnostic common policy, same dispatch as orion_metrics_rollup).
- SOURCE_ES_INDEX = 'cloud-governance-clouds-billing-reports', DEST = 'cloud-governance-orion-cost-metrics-index', SPEND_POLICIES = [...].
- Query: monthly date_histogram on start_date (calendar_interval=month) → sub-agg by_cloud (sum Actual) → build per-month doc. Filter to completed months.
- Backfill mode (date range, chunked) + daily incremental (recompute completed months), upsert by deterministic uuid — reuse the exact patterns from orion_metrics_rollup.
  • Register in COMMON_POLICIES in environment_variables.py; add env vars (orion_cost_es_index, orion_cost_rollup_start/end_date).
  • Unit tests mirroring test_orion_metrics_rollup.py.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added automated monthly Orion cost rollups by cost center and cloud provider.
    • Added configurable cost data sources, date ranges, and cost centers.
    • Added monthly backfill processing with support for targeted date ranges.
  • Bug Fixes
    • Added validation for missing, reversed, or incomplete date ranges, with safe fallback to incremental processing.
    • Excluded current and future months from rollups.
    • Improved handling of missing cost data and repeat processing.

Walkthrough

The PR adds the orion_cost_metrics_rollup common policy. The policy loads Orion cost settings, aggregates completed monthly multi-cloud billing data, upserts Elasticsearch documents, and supports incremental and monthly backfill execution.

Changes

Orion cost metrics rollup

Layer / File(s) Summary
Configuration and monthly boundaries
cloud_governance/main/environment_variables.py, cloud_governance/policy/common_policies/orion_cost_metrics_rollup.py
Loads four Orion cost settings, registers the policy as common, validates date sources, and splits valid ranges into monthly chunks.
Monthly aggregation and Elasticsearch writes
cloud_governance/policy/common_policies/orion_cost_metrics_rollup.py, tests/unittest/cloud_governance/policy/common_policies/test_orion_cost_metrics_rollup.py
Queries completed monthly billing data, maps cloud spend fields, and creates or updates deterministic Elasticsearch documents. Tests cover aggregation, filtering, mapping, and write behavior.
Run modes and validation
cloud_governance/policy/common_policies/orion_cost_metrics_rollup.py, tests/unittest/cloud_governance/policy/common_policies/test_orion_cost_metrics_rollup.py
Supports incremental processing and monthly backfills with pauses and document counts. Tests cover partial dates, mixed date sources, leap years, year transitions, and query counts.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 8b436

Backfills with partial-month date boundaries can write complete monthly totals outside the requested range, potentially overwriting cost metric documents unexpectedly. The range handling should be corrected or explicitly accepted before merging.

In `@cloud_governance/policy/common_policies/orion_cost_metrics_rollup.py`:
- Around line 211-213: Update the date selection logic around
__custom_start_date and __custom_end_date so direct start_date/end_date
arguments are treated as one pair: if either direct boundary is provided, use
only those direct values and do not backfill from configuration; otherwise use
the configured pair. Preserve the partial-range guard so incomplete direct input
does not update rollup documents, and add a regression test covering one direct
boundary with the opposite configured boundary.
- Line 220: Update the backfill flow around __process_date_range so the
requested start_date–end_date range is divided into bounded month-sized chunks;
process and upsert each chunk before advancing to the next, rather than
submitting the complete range in one aggregation request. Preserve existing
behavior for each chunk and ensure the final partial month is included.

Comment thread cloud_governance/policy/common_policies/orion_cost_metrics_rollup.py Outdated
Prevent direct caller boundaries from being mixed with configured defaults.
When either direct boundary (start_date or end_date param) is provided,
both must come exclusively from the direct input—no mixing with config values.
Partial ranges now properly fall back to incremental mode regardless of source.

Added regression test for direct start_date with configured end_date to ensure
the partial-range guard works across boundary sources.

124-124: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Require complete calendar months for a backfill.

The source stores monthly rows keyed by start_date. A range such as 2024-01-01 through 2024-01-15 selects and writes January’s complete Actual total. A range such as 2024-01-15 through 2024-02-15 omits January and selects February’s complete total. These documents overwrite the deterministic month UUIDs with values outside the requested range.

Reject non-month-aligned boundaries, or normalize the range to fully contained completed months before building the query. Add boundary-range tests.
