Usage Statistics

The optional stats plugin adds a Statistics page where you can review model usage, tracked spend and cache use.

The plugin adds a page, not chat tools. Without it, the in-chat usage views still work: see Usage and cost figures.

Read model usage statistics

  1. Open Statistics in the navigation.
  2. Choose a period in Date range: Today, Last 7 days, Last 30 days, Last 90 days, All time or Custom.

The selected period sets Total tokens, Tracked cost and Cache tokens at the top of the page, and it is remembered in this browser for your next visit.

Below the totals you get a model search, a usage filter for All, With cost or Loaded from cache, charts for tokens and cost by model, a daily trend and Usage by model, one card per model with its tokens, cost and cache share. Use the pager to change how many cards a page shows; the default is 20.

Select a model card to open Model detail. It shows input tokens, output tokens, cache read, cache write and cache hit rate.

What counts in the numbers

Statistics include recorded chat, voice, sessionless inference and embedding requests, and they survive deleting the conversation. An embedding request counts when it is sent through a configured provider for an account.

Each date covers one complete UTC day. A model without price data is shown with a dash (“—”), while a known free price counts as zero, and totals sum the known prices. Generation speed and where a price came from are not part of these totals.

The daily trend covers at most the latest 90 days. Pick an older period and the trend says it is available only for the latest 90 days. A period without usage shows an empty state; if the page cannot reach Chetty, it shows an error with a retry option.

See usage by account or address

Administrators can switch between My statistics and Whole instance. The Consumption origin button opens a panel that ranks usage by Users, Addresses or User and address.

  1. Open Consumption origin and choose what to rank by.
  2. Sort with Tokens or Cost. They are separate rankings, because the account with the most tokens is not always the most expensive one.
  3. Select a user row to see that user's addresses.

The panel also separates Scheduled and internal runs, Local access and Channel entries. An address counts as verified only when the request passed through the configured reverse proxy and trust for that proxy is enabled. Otherwise it comes from the client and is shown as an unverified source with a warning.

Note: An address identifies a connection, not a person, and data retention can remove one; it is then labelled as removed.

Origin figures come from their own tally, so they can differ from the totals on the main page. The panel shows the date from which origin data exists, and usage from before that date is not included.

Reset the monthly limit

  1. Open Users and choose the account.
  2. In Limit and spend, select Reset monthly limit.
  3. Confirm in the Reset the monthly limit? dialog.

For the rest of the month, that account's monthly limit counts spend from zero. Recorded usage, statistics, provider account spend and conversations are unchanged. The Statistics page has no reset control of its own.

Install and enable

  1. Open Settings → Available plugins and install stats.

The plugin needs Chetty 0.29.112 or newer. It has no settings, chat tools or per-user grant. Each signed-in account sees its own usage; administrators can also open whole-instance statistics and the origin breakdown.

Note: Enabling, disabling, installing or changing a plugin restarts Chetty. The settings screen says, "Change saved. Chetty is restarting now to load it."
