Metrics

Cachet allows you to track arbitrary metrics on your status page. A metric can represent anything measurable, such as the number of users on your platform, the number of requests per second, or even random things like the amount of cups of tea brewed.

A metric consists of:

• Name: The name of the metric, e.g. Users Online.
• Suffix: The suffix of the metric, e.g. users.
• Description: A description of the metric, e.g. The number of users currently online.
• Default View: How to display the metric, e.g. Last hour, Today, Week, Month.
• Default Value: The default value of the metric when missing points, e.g. 0.
• Display Chart: Plot the metric in a chart on the status page, this can be enabled or disabled.
• Places: The number of decimal places to display.
• Metric Type: The type of calculation to perform on the metric, e.g. sum or average.
• Threshold: The threshold determines when a new point should be created or the last point updated.
• Visible: Whether the metric is visible to users, guests or always hidden.

​

Metric Points

A metric is made up of multiple points which are added over time. Each point consists of:

• Value: The value of the metric at this point in time.
• Timestamp: The time the metric was recorded.

For performance, if a metric point is created within the threshold of an existing point, the existing point will be updated with the new value.
