Total token use Gemini API

Total token use is not monitored in AI Studio, just input tokens. Spend has a massive lag.

This is obviously a Tier 1 observability failure, as it’s used for billing.

Metrics Explorer in Cloud Monitoring is an utter mess, and doesn’t seem to have the relevant options either (I tried several recommended methods, but without success).

Does anyone have tips on monitoring real-time total token use? Thanks!
