GCP cost monitoring

Catch GCP overspend across every project and folder

CostMon reads your GCP billing export straight from BigQuery and turns scattered project- and folder-level spend into one normalized daily view — so a forgotten BigQuery job or an expiring committed-use discount gets caught before the invoice lands.

GCP BigQuery billing export — live today

GCP's own billing console is built around one project or one billing account at a time — the moment spend is spread across a dozen projects and folders (which it always is), there's no single place that shows the total, let alone catches a runaway BigQuery scan or an egress spike while it's still cheap to fix. Committed-use discounts silently expire, orphaned Compute Engine disks stack up, and by the time it all reconciles onto the invoice, the spend is already sunk.

Why CostMon

Built for GCP spend, from day one

Every project and folder, one total

CostMon reads directly from your GCP FOCUS billing export in BigQuery, so a spend total that's split across a dozen projects and folders finally rolls up into a single normalized number.

Committed-use discounts, tracked not forgotten

See CUD coverage and expiration alongside daily spend, so a discount that's about to lapse — or usage that's drifted off it — shows up before it costs you full on-demand price.

BigQuery and egress spikes, caught early

A daily, service-level view surfaces a runaway BigQuery scan or an unexpected egress spike days after it starts, not a month later on the bill.

Read-only, cost-scoped credentials

CostMon connects with a service account scoped to bigquery.dataViewer and jobUser on your billing export only — read-only, and it never touches your workloads or production data.

FAQ

Common questions about the GCP connector

How does CostMon connect to GCP?

Through a read-only service account key scoped to bigquery.dataViewer and bigquery.jobUser on the dataset holding your FOCUS-formatted billing export — CostMon never requests access to your workloads or production data.

Does CostMon replace the GCP Billing console?

No — CostMon reads the same FOCUS billing export and normalizes it alongside AWS, Azure, and every other provider you connect, so GCP spend sits in one daily view instead of its own console.

Can CostMon see spend across multiple projects and folders?

Yes — the billing export already carries project and folder detail, and CostMon preserves it, so you can break spend down by project, folder, service, or SKU.

Does CostMon track committed-use discounts?

Spend syncs in with its underlying FOCUS detail intact, including discount and commitment fields where GCP's export provides them, so CUD coverage stays visible next to raw spend.

What does the GCP connector cost?

A flat monthly rate per plan — never a percentage of your GCP bill or the savings CostMon helps you find. Free includes 2 connectors; Professional and Enterprise include unlimited connectors.
