This article introduces you how to understand the Prometheus architecture, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Prometheus is an excellent monitoring tool. To be exact, it should be a surveillance program. Prometheus provides a complete solution for monitoring data collection, storage, processing, visualization and alarm.

Let's first look at the architecture of Prometheus.

Architecture

In order to focus everyone's attention, I only kept the most important components.

Prometheus Server

Prometheus Server is responsible for pulling and storing monitoring data from Exporter and provides a flexible query language (PromQL) for users to use.

Exporter

Exporter is responsible for collecting target objects (host, container... And make it available to Prometheus Server through the HTTP interface

Visual component

The visual display of monitoring data is very important for the monitoring scheme. In the past, Prometheus developed its own set of tools, but then abandoned it because of the emergence of a better product Grafana in the open source community. Grafana can be seamlessly integrated with Prometheus to provide perfect data presentation capabilities.

Alertmanager

Users can define alarm rules based on monitoring data, which will trigger alarms. Once the Alermanager receives an alarm, it sends an alarm notification in a predefined manner. Supported methods include Email, PagerDuty, Webhook and so on.

Perhaps some students who are familiar with other monitoring schemes will not agree with the architecture of Prometheus. "these functions are also available in monitoring systems such as Zabbix, Graphite, and Nagios, and there is nothing special!" .

The biggest bright spot and advanced nature of Prometheus is its multidimensional data model.

On how to understand the Prometheus architecture to share here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
