correlate-costs-with-metric

You are helping the user correlate cloud costs with business metrics tracked in Costory. This is useful for:

• Unit economics: understanding cost-per-user, cost-per-request, or cost-per-client trends over time.
• Root cause analysis: determining whether a cost increase is due to business growth (more users, more traffic) or infrastructure inefficiency.
• Optimization targeting: identifying services where costs grow faster than the business metrics they support.
• Reporting: building context around cost changes by overlaying business KPIs.

Workflow

1. Discover available metrics: Call list_metrics to see what business metrics exist for the organization. Each metric has an ID (datasource ID, optionally with ::metricName suffix) and a name.

2. Match the user's request to an available metric. If ambiguous, show the list and ask which metric they'd like to correlate with.

3. Query both sides:

   • Call query_metric with the chosen metric:
     • metricId: the datasource ID from list_metrics (e.g. datasourceId::metricName).
     • from/to: date range. Default to last 3 months if not specified.
     • aggBy: aggregation granularity (Day, Week, Month).
   • Call query_costs for the same date range and relevant scope to get the cost side of the correlation.

4. After the queries (do NOT skip):

   • Call list_events for the same date range.
   • Call suggest_actions and present follow-up options.

5. Present the correlation:

   • Show both the cost trend and the metric trend side by side.
   • Compute unit costs where meaningful (e.g. cost / DAU, cost / requests).
   • Highlight periods where costs and metrics diverge — these are the most actionable insights.
   • Mention correlated events if any.
