get-gcp-recommendation 

dci get-gcp-recommendation <billingAccountId> <gcp_service> [flags]

Returns the recommendation for one product line (gcp_service) and region scope on the GCP billing account, including analysis metrics and time-bucketed eligible spend. Use granularity to choose the eligible-spend bucket size (defaults to day).

region is an optional query param, defaulting to global. In v1 the only supported values are gcp_service=compute and region=global. When no stored recommendation matches the scope, recommendation is omitted and estimatedEquivalentRecommendedCommitment is 0.

  • billingAccountId — GCP Billing Account ID (format XXXXXX-XXXXXX-XXXXXX; the account that owns the CUDs) that scopes the request.
  • gcp_service — PS4C product line to fetch the recommendation for.

Flags​

FlagTypeDefaultExampleDescription
--regionstringFilter GCP planned purchases by region scope. Requires gcp_service; when omitted together with gcp_service, all available regions for all available product lines are returned. A request with region but no gcp_service returns 400 with code gcp_service_required. One of: "global".
--granularitystring"day"Time bucket size for eligible-spend data points on the recommendation response. If omitted, defaults to day. Coarser buckets return min/max/median usage; hour returns per-hour totals. One of: "hour", "day", "week", "month".

Every command also accepts the CLI-wide flags for output shaping — see Output formats and Table output options.

Output​

Recommendation detail with eligible-spend usage series.

By default dci renders the result as a table. Use --output json to get the full structure described below — see Output formats.

FieldTypeDescription
estimatedEquivalentRecommendedCommitmentnumber (double)Shelf-price hourly equivalent ($/h) of the recommended commitment, derived from the median hourly eligible usage over the trailing window multiplied by estimatedAverageCoverage. Use this to compare the recommendation line to eligible usage on charts.
recommendationobjectRecommended commitment metrics for the requested (service, region) scope.
recommendation.policystringCoverage target policy currently configured for this commitment type (display name). One of: "Conservative", "Balanced (Recommended)", "Max Savings".
recommendation.regionstringRegion scope for this recommendation. v1 supports global only. One of: "global".
recommendation.servicestringPS4C product line (gcp_service) this recommendation belongs to. One of: "compute".
recommendation.currentCommitmentnumber (double)Active hourly commitment ($/h) currently applied to this billing account and product line, including commitments already purchased.
recommendation.recommendedCommitmentnumber (double)Recommended total hourly commitment ($/h) based on usage patterns and your commitment policy. Designed to increase savings while managing underutilization risk.
recommendation.potentialAdditionalSavingsnumber (double)Estimated additional monthly savings ($/month) from applying the recommended commitment relative to currentCommitment.
recommendation.estimatedAverageCoveragenumber (double)Estimated average coverage (0–1) of eligible spend if the recommended commitment were in place.
eligibleUsagearray of objectEligible spend over time at the requested granularity. Empty when no eligible usage exists in the trailing window.
eligibleUsage[].usageTimestring (date-time)Start of the time bucket for this data point (UTC).
eligibleUsage[].totalUsagenumber (double)Total eligible usage in the bucket when granularity is hour. Prefer min/max/median for coarser granularities.
eligibleUsage[].minUsagenumber (double)Minimum eligible usage ($/h) observed in the bucket (day/week/month views).
eligibleUsage[].maxUsagenumber (double)Maximum eligible usage ($/h) observed in the bucket (day/week/month views).
eligibleUsage[].medianUsagenumber (double)Median eligible usage ($/h) observed in the bucket (day/week/month views).
