# Metrics

> What each number on the admin Metrics tab means, and how often it is counted.

The **Metrics** tab ([/admin#metrics](https://www.checkthatfield.com/admin#metrics)) shows how big the platform is and how it is growing.

## How the numbers are counted

The counts read large tables, so they are never worked out when you open the tab. Instead, a snapshot of every number is taken **once an hour** and the tab shows the latest. The line under the heading says when: "Counted every hour. Last counted 12 min ago."

* **Open fields** are the slowest count, so they are counted afresh **once a day** and carried between hourly snapshots.
* **Land parcels** is an estimate from the database's own statistics, not an exact count.
* If no snapshot exists yet, opening the tab takes the first one. That can take half a minute.

A few of these numbers are public, through the [public metrics endpoint](https://docs.checkthatfield.com/api/public-metrics.md): councils read, applications held, open fields, fields scored and reports.

## Councils

| Tile | Meaning |
| - | - |
| **Councils** | Every planning authority in England we hold a boundary for. |
| **With a pipeline** | Councils with at least one pipeline switched on. This is "councils read" in the public numbers. |
| **History complete** | Of those, councils whose pipeline has read all the way back through its history. |
| **Failing** | Councils with a pipeline switched on that is failing or blocked. Look at the Pipelines tab. |

## Applications

| Tile | Meaning |
| - | - |
| **Held** | Every planning application we hold, of any kind. |
| **For homes** | Of those, applications for new homes. These are the ones the scores and the API use. |
| **On the map** | Applications with a location. The line below splits it: from the council's own location, from the postcode, and from the address. |
| **New in 24 h**, **New in 7 days** | Applications first seen in that time. |

## Fields

| Tile | Meaning |
| - | - |
| **Land parcels (about)** | Every land parcel we hold, estimated. Most are gardens, buildings and roads, not fields. |
| **Open fields** | Parcels that are open land and at least 0.2 hectares: the fields we can score. Counted once a day. |
| **Scored** | Fields with a score under the current scoring model. Scores from an older model aren't counted. |
| **Share scored** | Scored as a share of open fields. |

Under the tiles, **Scored fields by band** splits the scored fields into Low, Moderate, High and Very High, with each band's count and share.

## Reports and searches

| Tile | Meaning |
| - | - |
| **Reports** | Every report made, free and deep. |
| **Reports in 7 days** | Reports made in the last 7 days. |
| **Failed in 7 days** | Reports in the last 7 days that failed. A rise is worth looking into. |
| **Deep reports bought** | Paid purchases, ever. |
| **Searches in 7 days** | Map searches by people in the last 7 days. Crawlers are left out. API and widget lookups aren't searches. |

## Partners

| Tile | Meaning |
| - | - |
| **Active keys** | Keys not revoked, API and widget together. |
| **API calls in 7 days** | Calls to the API counted against all keys' quotas, over the last 7 days including today. Widget loads are not included; see the widget lines below. |
| **Widget views in 7 days** | Widgets seen on partners' pages. See [Security and privacy](https://docs.checkthatfield.com/widget/security-and-privacy.md) for what counts as a view. |
| **Widget clicks in 7 days** | Clicks from a widget to a full report or the map. |

For one partner's numbers, see the [Keys](https://docs.checkthatfield.com/admin/keys.md#read-usage) tab.

## The trend lines

At the foot of the tab, three lines cover up to the last 90 days: new applications, fields scored and reports, each a day. A day's figure is how much its total grew since the day before, from the last snapshot of each day (UTC). Hover over a line to see a day's figure; the number beside each title is the sum over the days shown. The lines appear once there are snapshots from at least three days.
