SUMMARY

Expose Prometheus metrics for indirect node counting at
/api/v2/metrics?subsystemonly=1, following the existing DispatcherMetrics
pattern. This is a prerequisite for perf/scale testing (AAP-57413) before
the feature flag can be removed for GA in 2.7.

Metrics added:

  • indirect_node_audit_records_created (counter)
  • indirect_node_query_execution_seconds (accumulated float)
  • indirect_node_jq_query_errors (counter)
  • indirect_node_fallback_cleanup_seconds (latest-value float)

Instrumentation points in host_indirect.py:

  • jq query execution timing and error counting in build_indirect_host_data
  • audit record count after bulk_create in save_indirect_host_entries_of_job
  • fallback cleanup job wall-clock timing

Also registers IndirectCountingMetrics in send_subsystem_metrics for
cross-node metric broadcasting.

Summary by CodeRabbit

  • New Features

    • Added monitoring for indirect host processing, including audit record creation, query execution time, query errors, and fallback cleanup duration.
    • Included these metrics in application metrics output and periodic reporting.
    • Added warnings when metrics cannot be flushed successfully.
  • Tests

    • Updated indirect host processing tests to support and verify metrics collection during processing.

📝 Walkthrough

Walkthrough

Changes

The change adds IndirectCountingMetrics with four indirect host metrics. Indirect host processing records query timing, query errors, audit records, and fallback cleanup duration. Scheduled dispatch and the metrics endpoint export these values.

Indirect host metric definitions and exposure

Layer / File(s) Summary
Metric definitions and exposure
awx/settings/defaults.py, awx/main/analytics/subsystem_metrics.py
The indirect_counting namespace defines four metrics and adds them to the metrics endpoint.
Indirect host instrumentation
awx/main/tasks/host_indirect.py
Indirect host processing records query duration, query errors, created audit records, and fallback cleanup duration. Metric flushing logs a warning when it fails.
Subsystem dispatch and validation
awx/main/analytics/analytics_tasks.py, awx/main/tests/functional/tasks/test_host_indirect.py, awx/main/tests/live/tests/test_indirect_host_counting.py
The subsystem metrics task sends indirect counting metrics. Affected test calls pass the new metrics argument.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to f758e

Audit-record metrics can overstate persisted records after a failed insertion transaction, reducing monitoring accuracy. Merge should wait until counting occurs only after a successful commit.

original MR was much smaller, code coverage + forced refactoring on old-out-of-scope-code (sonarqube..) grew the size of this by quite a bit
