rvice - The Prometheus monitoring system and time series database.

Save it, start and enable the service with the command: sudo systemctl start prometheusĬheck the status of the service: $ systemctl status rvice Make sure that the file fits your initial settings for Prometheus. # The job name is added as a label `job=` to any timeseries scraped from this config. # scrape_timeout is set to the global default (10s). Default is every 1 minute.Įvaluation_interval: 15s # Evaluate rules every 15 seconds.

Scrape_interval: 15s # Set the scrape interval to every 15 seconds. The default configuration file is at /etc/prometheus/prometheus.yml sudo vim /etc/prometheus/prometheus.yml Once installed, Prometheus stores its data at /var/lib/prometheus and config files at /etc/prometheus/. Once the repository has been added, Prometheus can be installed with the command: sudo dnf install prometheus -y The repositories need to be added to the system to be able to install Prometheus.īegin by enabling the EPEL repository: sudo dnf -y install epel-release vimĬreate the repository: sudo vim /etc//prometheus.repoĪdd the below lines to the file: curl -s | sudo bash 2. Prometheus is not provided in the default Rocky Linux 9 / AlmaLinux 9 repositories. Node exporter is used to expose the hardware and kernel-related metrics on Linux systems. The diagram below can be used to illustrate the Prometheus Architectureįor Prometheus to collect the metrics, you need to install the ‘ exporter‘ application to expose the data and metrics. Special-purpose exporters – for services such as HAProxy, StatsD, Graphite e.t.c.Push gateway – to support short-lived jobs.

Client libraries – used to instrument application code.

Prometheus server – scrapes and stores time series data.

The Prometheus ecosystem encompasses several components. For example, on web servers, you might be interested in request times, for database servers, it might be the number of active queries/connections. They may be different from one application to the other. Metrics are usually numeric measurements that vary from time to time. This means that the metrics are stored with the timestamp at which they were collected. Prometheus works by collecting and storing metrics as time series data.

It supports multiple modes of graphing and dashboarding.

Targets are discovered via service discovery or static configuration.

It uses a multi-dimensional data model where time series data is identified by metric name and key/value pairs.

It doesn’t rely on distributed storage single server nodes are autonomous.

It uses PromQL, which is a flexible query language to leverage this dimensionality.

Time-series metrics collection which happens via a pull model over HTTP.

Prometheus is preferred due to the following features: In 2016, it was elevated to the Cloud Native Computing Foundation as the second hosted project after Kubernetes. Prometheus was then adopted by several companies and active developers around the world. It was originally developed by SoundCloud in 2012. Prometheus is a free and open-source toolkit used for time series event monitoring and alerting.
