# General information about the Metrics service

The Metrics service is designed for collecting, storing, and analyzing metrics of Selectel products.

You can collect metrics for:

* dedicated servers;
* cloud servers, attached volumes, and private networks.

Metrics allow you to evaluate resource utilization, identify bottlenecks in your applications and infrastructure, and distinguish between one-time anomalies and systemic degradation.

## How it works \{#principle-of-operation}

![](https://423.selcdn.ru/kb/metrics-about-metrics-principle-of-operation-LANG-THEME.png)

The Metrics service automatically collects metrics on the state of your resources. A metric (metric) is a quantitative indicator of performance in [Prometheus-format](https://prometheus.io/docs/concepts/data_model/).

A metric is a single entry consisting of three components:

* `metric_name` – the name of the metric;
* `label_name` – the name of the metric label;
* `label_value` – the label value.

Metrics that relate to specific products or services are grouped into a namespace (namespace). Namespaces are fixed and cannot be changed.

## How to use the Metrics service \{#working-with-metrics}

You can view and analyze metrics using metric collection agents:

* [Prometheus](/metrics/tools/prometheus.mdx);
* [VMAgent](/metrics/tools/vmagent.mdx);
* [Telegraf](/metrics/tools/telegraf.mdx).

You can also visualize metrics using [Grafana](/metrics/tools/grafana.mdx) or view [system dashboards](/metrics/manage/dashboards.mdx) in the Control Panel.

You can check the availability of the Metrics service across regions in the [Metrics](/infrastructure/product-availability-by-location.mdx#metrics) availability matrix.

## Pricing \{#price}

The service is currently provided free of charge. We will notify you in advance when the service becomes billable in the future.
