Refer to Prometheus's storage documentation for detailed usage.Īs this is the first time we have run the command this will download the contents from Dockers hub. This is a value you will definitely need to tune when running Prometheus on a machine with more RAM and when storing more time serie It instructs Prometheus to keep only 10000 sample chunks in memory (roughly 10 chunks per series), instead of the default of 1048576.

The option configures the metrics storage location within the container.įinally, the -chunks option adjusts Prometheus's memory usage to the host system's very small amount of RAM (only 512MB) and small number of stored time series in this tutorial (just under 1000) The -config.file option is instruct the Dockers accordingly to the location of the Prometheus configuration file within the container. The -v option mounts the prometheus.yml configuration file from the host filesystem from the location within the container where Prometheus expects it (/etc/prometheus/prometheus.yml) The -p 9090:9090 option allows the Prometheus's web port (9090) and makes it reachable via the external IP address of the host system. We will see each and every option used in the above command The -d option starts the Prometheus container to start in detached mode, meaning that the container will be started in the background and will not be terminated by pressing CTRL+C. This command is quite long and contains many commands in one line with many options. Start the Prometheus Docker container with this external configuration file using the below command $ docker run -d -p 9090:9090 -v ~/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus -config.file=/etc/prometheus/prometheus.yml =/prometheus -chunks=10000 # Scrape the Node Exporter every 5 seconds. # Scrape Prometheus itself every 5 seconds. # A scrape configuration scraping a Node Exporter and the Prometheus server Creating a Minimum Prometheus Configuration $ nano ~/prometheus.yml A custom configuration file may be used into the container from the host system as a Docker data volume or we can choose a build Docker container with our own configuration, her for demo purpose we will choose to pass in the config file from the host system.
We have multiple ways of overriding the default config files. We can start the Docker image without using any options using the demo configuration which is located at /etc/Prometheus/Prometheus.yml. Dockers container images for Prometheus components are located under the prom organization from the Dockers Hub. We are installing the Prometheus using the Dockers, so make sure that we already installed Docker on the CentOS 7 machine. To complete this article we needed these resources CentOS 7 installed, a user with sudo access and Dockers installed. It addresses many aspects for monitoring and generating a collection of metrics and graphs for resulting the data on the dashboards along with alerting. Prometheus is an open source monitoring tool with time series database.

In this article, we will learn how to install Prometheus server to collect the metrics and query them and also install Grafana – a web based graphical dashboard builder.
