+The Usage page provides a single place to track plan quotas, current 
+consumption, and any charges for the selected period. Use it to understand

+1. Access the [Vectara Console](https://console.vectara.com/console).
+2. Select the [**Usage**](https://console.vectara.com/console/usage/resource-usage) tab.
+
+At the top of the page you’ll see the reporting window, for example:
+
+**Period from 05‑Aug‑2025 to 31‑Aug‑2025**
+
+Usage numbers reflect activity within this window. Resource usage numbers 
+might be delayed by up to four hours.
+
+## Resource usage
+
+The table summarizes each tracked resource with its current usage, plan base 
+quota, and percentage consumed:
+
+### Data storage
+Shows used storage out of your plan base quota (like 119.2 of 100 MB).
+
+### GPT‑4 generative requests
+Counts generative API calls against the plan base quota (like 12,853 of 
+20,000 requests). The percentage used appears beneath the count.
+
+### Corpora
+Tracks how many corpora are provisioned with a percentage used.
+
+### Users
+Tracks the number of users provisioned in your tenant with a percentage used.
+
+:::tip
+When a metric approaches its limit, consider archiving unused data, reducing 
+request volume, or working with your admin to adjust plan capacity.
