# Consumption Rates - Metric Monitor Extended Scale - Version 2.1

This document details an extended Consumption Rate scale for Metric Monitors. Click [here](https://docs.getmontecarlo.com/docs/version-21) to see Consumption Rates for all Monitor types.

## Metric Monitors

Metric Monitors are used to detect anomalies in statistical or business metrics, or reconcile those metrics across different warehouses.

Included Monitor types: Metric, Comparison

The Consumption Rate is measured per Monitor, based on the count of metrics tracked by that Monitor. The count of metrics is calculated as the number of field-metric pairs, multiplied by the number of segments tracked by that Monitor. The count of segments is measured using the number of distinct segments collected in the second-most-recent run of the monitor. A value of "1" will be used for the count of segments in the event no segments were collected.

Some examples:

* a Metric Monitor tracking the `Null (%)` for 1 field counts as 1 metric
* a Metric Monitor tracking the `Null (%)` for 2 fields and 20 segments counts as 40 metrics (2 x 20)

**Most Metric Monitors that get created are simple.** Across the customer base, the median Metric Monitor tracks 1 metric (1 credit/day). Only 5% of Metric Monitors are tracking more than 100 metrics, and only 1% track more than 1,000 metrics.

However, when needed, a Metric Monitor can be scaled to track up to 1 million metrics, with Consumption Rates as defined below:
