Data model

Yandex Monitoring stores data as time series.

Metrics

Metrics are time series that shows a change of some value over time. For example, the resource status of a Yandex.Cloud service: the amount of used disk space, network data transfer rate, and so on.

Metrics are identified using text labels.

Labels

A label is a metric characteristic in key: "value" format. Each metric is identified by an unordered set of labels. Use a parameter that takes a limited set of values as a label. For example, the HTTP status code, the types of procedures being performed in a database, and so on.

The service has mandatory and optional labels. Mandatory labels:

  • project: The ID of the cloud that the resource belongs to.
  • cluster: The ID of the folder that the resource belongs to.
  • service: Indicates the Yandex.Cloud service that the resource belongs to. For example, compute or managed-postgresql.

Warning

When uploading custom metrics, you should write the custom value in the service label.

The Yandex Monitoring service offers the following metric types:

Type Description
DGAUGE Numeric value (decimal). It shows the metric value at a certain point in time. For example, the amount of used RAM
IGAUGE Numeric value (integer). It shows the metric value at a certain point in time.
