Key Takeaways

Monitor 164192487 or related order rejection alerts fire.
Quantify drop by action:
Check if submissions are normal but confirmations are low.
Review workflowservice errors in alert window.
Check payment auth/capture path if orders stall at payment steps.

Trigger

Monitor 164192487 or related order rejection alerts fire.

Triage Steps

Quantify drop by action:

SELECT "@event.action", count(*) FROM logs
WHERE service = 'workflowservice'
GROUP BY "@event.action"
ORDER BY count(*) DESC

Check if submissions are normal but confirmations are low.
Review workflowservice errors in alert window.
Check payment auth/capture path if orders stall at payment steps.
Check 181521332 (RDS CPU) for persistence bottlenecks.
Segment by organization for brand-specific issues.

Escalation

Order-delivery on-call for workflow and order path failures.
Payments on-call if payment step is gating confirmations.
SRE on-call for Temporal or RDS saturation patterns.

Recovery Validation

Confirmed order trend returns to baseline.
No sustained backlog in workflow transitions.
Affected brands report normal order lifecycle progression.
